Trail Wrist

WEBVTT

1
00:00:00.000 --> 00:00:05.000
All right, coaches, here we go again for another installment of the 3D series.

2
00:00:05.000 --> 00:00:08.000
This time we're going to be looking at the trail wrist angles.

3
00:00:08.000 --> 00:00:12.000
So we're going to be studying the graph that you see here.

4
00:00:12.000 --> 00:00:17.000
There's a few really important things to look at with the trail wrist,

5
00:00:17.000 --> 00:00:22.000
and then there's a few things where the way that the sensors collect the data,

6
00:00:22.000 --> 00:00:26.000
it's going to be tricky to draw too many big conclusions.

7
00:00:26.000 --> 00:00:31.000
So let's start digging into what I mean by all that.

8
00:00:31.000 --> 00:00:34.000
So as always, we'll cover the anatomy,

9
00:00:34.000 --> 00:00:40.000
and then we will look at the tour examples as well as the TPI guidelines

10
00:00:40.000 --> 00:00:45.000
so you have an idea of what to look for when you're looking at the trail wrist.

11
00:00:45.000 --> 00:00:50.000
So the three movements we're looking at are flexion extension,

12
00:00:50.000 --> 00:00:53.000
radial and ulnar deviation, so this way.

13
00:00:53.000 --> 00:00:59.000
And then a forearm movement, pronation, supination, rotating just like that.

14
00:00:59.000 --> 00:01:05.000
Okay, on these graphs where all the three are on it together,

15
00:01:05.000 --> 00:01:08.000
if you look at the bottom, that'll tell you what color is what.

16
00:01:08.000 --> 00:01:13.000
So we've got red line is trail wrist, green line is...

17
00:01:13.000 --> 00:01:18.000
Sorry, red line is ulnar radial deviation, green line is flexion extension,

18
00:01:18.000 --> 00:01:22.000
and then blue line is pronation, supination.

19
00:01:22.000 --> 00:01:26.000
So this is kind of the classic pattern that we'll see here.

20
00:01:26.000 --> 00:01:28.000
We'll bring up another one.

21
00:01:28.000 --> 00:01:32.540
You know, there's some differences in terms of overlapping and scale and things

22
00:01:32.540 --> 00:01:33.000
like that.

23
00:01:33.000 --> 00:01:40.360
We'll discuss a little bit, but some similar patterns and timings of dips and

24
00:01:40.360 --> 00:01:41.000
peaks

25
00:01:41.000 --> 00:01:44.000
are going to be evident when we jump through them.

26
00:01:44.000 --> 00:01:48.000
Because when we look at all three of them together,

27
00:01:48.000 --> 00:01:52.000
you can see green line has some big similarities.

28
00:01:52.000 --> 00:01:59.000
Blue line has this kind of peak after the top, varying flat lines in transition

29
00:01:59.000 --> 00:01:59.000
,

30
00:01:59.000 --> 00:02:05.000
peaking up around impact, little plateau around impact.

31
00:02:05.000 --> 00:02:11.000
Red line has kind of a double peak or a single peak going into the downswing.

32
00:02:11.000 --> 00:02:15.000
We'll talk about what all those patterns mean.

33
00:02:15.000 --> 00:02:20.000
But as always, remember, especially with this trail wrist,

34
00:02:20.000 --> 00:02:24.000
don't just look at the graph for specific answers.

35
00:02:24.000 --> 00:02:27.000
It'll help you figure out what to investigate.

36
00:02:27.000 --> 00:02:30.000
Never look at only one graph.

37
00:02:30.000 --> 00:02:33.530
So look at the lead wrist, look at the trail wrist, look at the thorax

38
00:02:33.530 --> 00:02:34.000
positions.

39
00:02:34.000 --> 00:02:39.000
Those are all going to help you figure out how is this golfer transferring

40
00:02:39.000 --> 00:02:39.000
energy

41
00:02:39.000 --> 00:02:41.000
from the handle to the club head?

42
00:02:41.000 --> 00:02:42.000
How are they controlling the path?

43
00:02:42.000 --> 00:02:44.000
How are they controlling the face?

44
00:02:44.000 --> 00:02:46.000
How are they creating speed?

45
00:02:46.000 --> 00:02:48.000
All that good stuff.

46
00:02:48.000 --> 00:02:52.000
With this, it will be important to look at about what position,

47
00:02:52.000 --> 00:02:56.000
so what phase of the swing are these movements happening?

48
00:02:56.000 --> 00:02:59.000
And what would that be doing to the path and the face?

49
00:02:59.000 --> 00:03:00.000
So how would I have to balance it?

50
00:03:00.000 --> 00:03:03.000
What other movements need to overlap?

51
00:03:03.000 --> 00:03:07.000
One good thing that you can do with 3D that I don't think I've mentioned

52
00:03:07.000 --> 00:03:10.000
is when you have like four or five movements that are all looking

53
00:03:10.000 --> 00:03:13.000
like they're happening at the same time, you can scroll through

54
00:03:13.000 --> 00:03:16.000
and you can look at which one actually happened first.

55
00:03:16.000 --> 00:03:20.000
Oftentimes, if you fit that first move is the trigger

56
00:03:20.000 --> 00:03:23.000
and then the remaining moves are more of the compensations.

57
00:03:23.000 --> 00:03:27.000
So if you correct, you'll have to usually correct more than one,

58
00:03:27.000 --> 00:03:30.000
but if you correct that first trigger, sometimes it helps the other

59
00:03:30.000 --> 00:03:32.000
dominoes fall in place.

60
00:03:32.000 --> 00:03:36.000
So big pictures with the 3D is you can look at the movement as a whole

61
00:03:36.000 --> 00:03:40.000
and you can look at the whole body all at once, so you can look at

62
00:03:40.000 --> 00:03:44.000
kind of the relationships or what's moving.

63
00:03:44.000 --> 00:03:49.000
Is it the inner muscles, the outer muscles?

64
00:03:49.000 --> 00:03:52.000
Is it just one segment or is it the whole body working the other?

65
00:03:52.000 --> 00:03:57.000
3D gives you a lot of insights into answering those questions.

66
00:03:57.000 --> 00:04:01.000
Okay, the key anatomy for looking at the wrist graft is looking at

67
00:04:01.000 --> 00:04:04.000
what's going on in the hand and the wrist, what's going on in the form,

68
00:04:04.000 --> 00:04:08.000
and then thinking about the shoulder and what's happening there.

69
00:04:08.000 --> 00:04:13.000
So some of the big muscle chains, are they using their traps

70
00:04:13.000 --> 00:04:16.000
and their neck muscles, or are they using their chest,

71
00:04:16.000 --> 00:04:19.000
or are they using their lats, what are they doing at the shoulder?

72
00:04:19.000 --> 00:04:23.000
That might give us some insight into how they might be thinking

73
00:04:23.000 --> 00:04:25.000
about using their wrist.

74
00:04:25.000 --> 00:04:28.000
Okay, first the bony stuff going on.

75
00:04:28.000 --> 00:04:33.000
So your forearm has two bones, the ulna and the radius.

76
00:04:33.000 --> 00:04:37.000
The ulna is this bone here on the pinky side and then the radius

77
00:04:37.000 --> 00:04:42.000
is on the thumb side, they meet at the elbow right here,

78
00:04:42.000 --> 00:04:46.000
and the radius can rotate over the ulna.

79
00:04:46.000 --> 00:04:52.000
So you see this joint here, this can rotate over kind of like this.

80
00:04:52.000 --> 00:04:57.000
At the wrist segment, the radius is bigger at the elbow segment,

81
00:04:57.000 --> 00:04:59.000
the ulna is bigger.

82
00:04:59.000 --> 00:05:04.000
So they have kind of this tapering shape going from one end to the other.

83
00:05:04.000 --> 00:05:07.000
At the wrist segment, the radius is also tighter,

84
00:05:07.000 --> 00:05:12.000
that's where kind of the force is easiest transferred.

85
00:05:12.000 --> 00:05:16.000
There's more space here, so there's more range of motion.

86
00:05:16.000 --> 00:05:20.000
So oftentimes we transfer force through the radius,

87
00:05:20.000 --> 00:05:24.000
and then we need to transfer that force from the radius to the ulna

88
00:05:24.000 --> 00:05:27.000
in order to take it up through the humerus into the shoulder,

89
00:05:27.000 --> 00:05:32.000
or it's more economical, energy-wise, if you do that.

90
00:05:32.000 --> 00:05:39.000
That's one of the reasons why we go into supination with the lead wrist.

91
00:05:39.000 --> 00:05:43.000
But this presentation is about the trail wrist, so that was just a fun little

92
00:05:43.000 --> 00:05:44.000
side.

93
00:05:44.000 --> 00:05:47.000
Understand that because of this anatomy here,

94
00:05:47.000 --> 00:05:52.000
you're going to have less movement going when you're doing radial deviation

95
00:05:52.000 --> 00:05:56.000
than when you're doing ulnar deviation, largely because there's less space

96
00:05:56.000 --> 00:05:58.000
and the bones run into each other.

97
00:05:58.000 --> 00:06:03.000
This is just to help you remember that the hand is not a flat plane,

98
00:06:03.000 --> 00:06:05.000
so when you're looking at these pictures,

99
00:06:05.000 --> 00:06:10.000
understand that it's in kind of a curved bowl shape, kind of like this.

100
00:06:10.000 --> 00:06:13.000
It's not flat like that.

101
00:06:13.000 --> 00:06:18.000
So that can change how you would think about some muscle attachments

102
00:06:18.000 --> 00:06:22.000
or vectors, or maybe it might not change anything,

103
00:06:22.000 --> 00:06:24.000
but it's important for you to know.

104
00:06:24.000 --> 00:06:30.000
This slide was actually taken from a website that deals with carpal tunnel,

105
00:06:30.000 --> 00:06:36.000
so this wrist segment here, there's a ligament or piece of fascia

106
00:06:36.000 --> 00:06:40.000
that wraps over it just like this, so you've got your bowl

107
00:06:40.000 --> 00:06:43.000
and then you've got the ligament on top, and when that gets tight,

108
00:06:43.000 --> 00:06:47.950
that's when you typically get some of the pain and/or numbness associated with

109
00:06:47.950 --> 00:06:49.000
carpal tunnel.

110
00:06:49.000 --> 00:06:52.000
You can see that there's a lot of muscles there,

111
00:06:52.000 --> 00:06:55.000
and I'd say unless you're really into this stuff,

112
00:06:55.000 --> 00:06:58.000
you probably don't need to memorize all the different names and functions,

113
00:06:58.000 --> 00:07:01.000
but think about the direction the fibers are going.

114
00:07:01.000 --> 00:07:06.000
So you have a lot of big muscles here that are running more straight up and

115
00:07:06.000 --> 00:07:06.000
down,

116
00:07:06.000 --> 00:07:08.000
they do extension.

117
00:07:08.000 --> 00:07:13.000
Here you've got some muscles running diagonally,

118
00:07:13.000 --> 00:07:16.000
those are going to help induce a little bit of rotation.

119
00:07:16.000 --> 00:07:19.930
They're coming across this way, they're also going to help with radial

120
00:07:19.930 --> 00:07:21.000
deviation.

121
00:07:21.000 --> 00:07:25.000
In general, if you were to look at this,

122
00:07:25.000 --> 00:07:29.000
if you were to look at your arm and kind of divide it into segments,

123
00:07:29.000 --> 00:07:34.000
the extensors will be on the back side,

124
00:07:34.000 --> 00:07:38.000
the flexors will be on this front side,

125
00:07:38.000 --> 00:07:41.000
and then the ulnar deviators will be on the pinky side or the bottom,

126
00:07:41.000 --> 00:07:44.000
and the radial deviators or the ridge muscles will be on the top.

127
00:07:44.000 --> 00:07:49.000
The pronation supination muscles tend to be a little bit smaller,

128
00:07:49.000 --> 00:07:51.000
especially in pronation.

129
00:07:51.000 --> 00:07:54.000
Part of the reason why you have smaller pronation muscles

130
00:07:54.000 --> 00:07:59.000
is because you have a really big ability to pronate at the shoulder,

131
00:07:59.000 --> 00:08:02.000
and you have a lot of room to move the elbow out this way,

132
00:08:02.000 --> 00:08:06.000
which creates a strong lever arm for pronation.

133
00:08:06.000 --> 00:08:10.000
That's why we tend to not have as strong pronation muscles.

134
00:08:10.000 --> 00:08:14.600
The supination, I'm kind of locked, like I can't go too far this way at the

135
00:08:14.600 --> 00:08:15.000
shoulder,

136
00:08:15.000 --> 00:08:20.000
so I had to develop stronger supination muscles in the forearm.

137
00:08:20.000 --> 00:08:22.000
Here's just the artist rendition.

138
00:08:22.000 --> 00:08:26.000
It's not anatomically corrects all these attachments,

139
00:08:26.000 --> 00:08:30.000
but it's an artist rendition where you've got kind of the ridge muscles

140
00:08:30.000 --> 00:08:33.000
dividing your flexors from your extensors.

141
00:08:33.000 --> 00:08:38.000
So ridge muscles on top here, those right there,

142
00:08:38.000 --> 00:08:42.000
you've got your extensors more on this side and the flexors more on this side.

143
00:08:42.000 --> 00:08:46.000
Now you always hear that there are coupled movements at the wrist.

144
00:08:46.000 --> 00:08:50.000
There's a few things. You've got the joint shapes, you've got the ligaments,

145
00:08:50.000 --> 00:08:54.000
which we won't get into in this, and then you've got the muscles.

146
00:08:54.000 --> 00:09:01.000
But they do all tend to create more of this physiological diagonal axis,

147
00:09:01.000 --> 00:09:06.000
where I've got this x-ray and those two layers of wrist bones highlighted.

148
00:09:06.000 --> 00:09:11.000
Those wrist bones kind of work more almost like this,

149
00:09:11.000 --> 00:09:15.000
and so that creates more of this diagonal axis.

150
00:09:15.000 --> 00:09:18.000
So when I tend to go into radial deviation,

151
00:09:18.000 --> 00:09:22.000
I will also tend to go into extension and a little bit of pronation.

152
00:09:22.000 --> 00:09:25.000
That's kind of the natural physiological axis.

153
00:09:25.000 --> 00:09:29.360
When I tend to go into ulnar deviation, I will tend to go into flexion and sup

154
00:09:29.360 --> 00:09:30.000
ination.

155
00:09:30.000 --> 00:09:35.000
So the same muscles, the same joints, the same ligaments help those movements.

156
00:09:35.000 --> 00:09:40.000
In neutral, I can just flex or just hinge radial deviation.

157
00:09:40.000 --> 00:09:46.000
But in practice, if I'm trying to apply max force or use closer to end range,

158
00:09:46.000 --> 00:09:50.000
I'll start to have these movements bleed into one another.

159
00:09:50.000 --> 00:09:55.000
So just keep that in mind with why you might see some of the movements.

160
00:09:55.000 --> 00:09:59.000
Are they actually hinging or are they just trying to extend?

161
00:09:59.000 --> 00:10:03.400
And they've run out of room there, so they're stealing it more from the radial

162
00:10:03.400 --> 00:10:04.000
deviation or the hinge.

163
00:10:04.000 --> 00:10:08.000
These are good things to kind of think about when you're troubleshooting some

164
00:10:08.000 --> 00:10:08.000
of the

165
00:10:08.000 --> 00:10:12.000
more annoying or trickier wrist combinations.

166
00:10:12.000 --> 00:10:16.720
Now there's a lot of links in the arm, but here are two of the common arm sl

167
00:10:16.720 --> 00:10:18.000
ings that are relevant to golf.

168
00:10:18.000 --> 00:10:23.000
One, this one here, it's more relevant to the lead side,

169
00:10:23.000 --> 00:10:25.000
tending to go into extension.

170
00:10:25.000 --> 00:10:29.780
When you take your wrist into extension, you're going to tend to go into more

171
00:10:29.780 --> 00:10:31.000
of a trap shrug.

172
00:10:31.000 --> 00:10:35.000
So it's going to tend to have a pull this way.

173
00:10:35.000 --> 00:10:39.780
It wouldn't make sense to pull and kind of rotate that way if I wanted to pull

174
00:10:39.780 --> 00:10:40.000
this way,

175
00:10:40.000 --> 00:10:44.540
I would tend to use my bicep with my shoulder and my bicep is a supinator

176
00:10:44.540 --> 00:10:45.000
muscle.

177
00:10:45.000 --> 00:10:49.000
So it would tend to make more sense to go like that.

178
00:10:49.000 --> 00:10:55.600
This one over here is more of kind of this chop pattern through the inside of

179
00:10:55.600 --> 00:10:56.000
the shoulder.

180
00:10:56.000 --> 00:11:02.000
So I've got these back muscles here linking the tricep and ulnar deviation.

181
00:11:02.000 --> 00:11:08.000
Now you'll see that this is a fairly weak movement down here at the forearm.

182
00:11:08.000 --> 00:11:13.000
It's strong here in the upper arm, but it's also weaker here at the shoulder.

183
00:11:13.000 --> 00:11:17.810
So if I'm going to use this pattern, I really have to connect it and use more

184
00:11:17.810 --> 00:11:20.000
of those big trunk muscles.

185
00:11:20.000 --> 00:11:22.000
Well, there's an advantage to that.

186
00:11:22.000 --> 00:11:27.260
Not only do I create power more from the trunk, it also helps with creating the

187
00:11:27.260 --> 00:11:28.000
flat spot

188
00:11:28.000 --> 00:11:31.000
and delaying the club passing my body.

189
00:11:31.000 --> 00:11:36.000
So oftentimes when you see golfers kind of really pulling in,

190
00:11:36.000 --> 00:11:40.540
they're going to create more of this extension pattern at the wrist or stiff

191
00:11:40.540 --> 00:11:41.000
ening.

192
00:11:41.000 --> 00:11:46.000
So a lot of what looks like a really big wrist scoop down at the bottom,

193
00:11:46.000 --> 00:11:48.970
it's actually if you break it down and look at the wrist, the wrist isn't doing

194
00:11:48.970 --> 00:11:50.000
a ton of this movement.

195
00:11:50.000 --> 00:11:55.520
It's more happening at the shoulder kind of rotating in and they're just

196
00:11:55.520 --> 00:11:59.000
creating a ton of tension in the wrist and the forearm.

197
00:11:59.000 --> 00:12:04.350
But these are a couple of the slings to help visualize the connection of the

198
00:12:04.350 --> 00:12:06.000
shoulder to the wrist.

199
00:12:06.000 --> 00:12:11.030
But there are lots of links kind of on a smaller scale when looking at the

200
00:12:11.030 --> 00:12:13.000
relationship between those two.

201
00:12:15.000 --> 00:12:20.190
Arm goal is in the golf swing, there's probably more, but from a kinetic

202
00:12:20.190 --> 00:12:21.000
standpoint,

203
00:12:21.000 --> 00:12:25.050
I'm trying to transfer speed from the handle to the club, which means I'm

204
00:12:25.050 --> 00:12:30.000
trying to delay the speed getting into the handle until later, you know,

205
00:12:30.000 --> 00:12:31.000
delivery position.

206
00:12:31.000 --> 00:12:37.590
And then one of the big ones is getting the center mass of the club to shallow

207
00:12:37.590 --> 00:12:39.000
underneath the hand path.

208
00:12:39.000 --> 00:12:45.000
That doesn't necessarily mean that I have to have a shallow swing plane.

209
00:12:45.000 --> 00:12:49.210
That can happen from going from steep to less steep, but you do want to have,

210
00:12:49.210 --> 00:12:52.000
for your full swing, some level of shallowing.

211
00:12:52.000 --> 00:12:55.000
It's a common pattern among the toy level.

212
00:12:55.000 --> 00:13:00.540
Kinematics wise, the wrists are really crucial for squaring and controlling the

213
00:13:00.540 --> 00:13:03.000
club face to path relationship.

214
00:13:03.000 --> 00:13:09.000
And the wrists and forearms are really helpful for creating this shallowness.

215
00:13:09.000 --> 00:13:12.410
You can either do it from the trail shoulder, or you can do it from the lead

216
00:13:12.410 --> 00:13:15.000
forearm, or you can do it from your body.

217
00:13:15.000 --> 00:13:20.150
But you're going to probably want to include some shallowness into your swing

218
00:13:20.150 --> 00:13:21.000
pattern.

219
00:13:21.000 --> 00:13:24.660
We will be able to see a little bit of what's happening with the right shoulder

220
00:13:24.660 --> 00:13:26.000
in one of these graphs.

221
00:13:26.000 --> 00:13:31.000
Okay, that's enough of a little tease. Let's jump into the wrist graphs.

222
00:13:31.000 --> 00:13:36.000
Let's look at flexion and extension. So the trail wrist going this way.

223
00:13:36.000 --> 00:13:39.400
And I will say right off the bat, this is one of the more important trail wrist

224
00:13:39.400 --> 00:13:40.000
graphs.

225
00:13:40.000 --> 00:13:44.540
And so I'm happy that something like hack motion, this is a pretty simple one

226
00:13:44.540 --> 00:13:48.000
to look at, and it seems to be pretty powerful for golfers.

227
00:13:48.000 --> 00:13:54.110
So, we'll tend to have a slight extension at setup. I'll try to get this kind

228
00:13:54.110 --> 00:13:55.000
of inline area.

229
00:13:55.000 --> 00:13:59.240
So a slight extension at setup, more extended at the top of the swing, an

230
00:13:59.240 --> 00:14:05.000
increase of that extension until about shaft parallel in the downswing.

231
00:14:05.000 --> 00:14:10.920
And then it's starting to come out, but I'm more extended at impact than I was

232
00:14:10.920 --> 00:14:12.000
at setup.

233
00:14:12.000 --> 00:14:19.310
About 25 degrees is just kind of a rough number that I've seen fairly

234
00:14:19.310 --> 00:14:21.000
repeatedly.

235
00:14:21.000 --> 00:14:27.000
Okay, the key anatomical structures, looking at the thorax position.

236
00:14:27.000 --> 00:14:33.390
So if I have this extended position, then I typically have to also have this

237
00:14:33.390 --> 00:14:39.430
shoulder a little bit more wipey or I have to have that elbow a little bit more

238
00:14:39.430 --> 00:14:40.000
in front.

239
00:14:40.000 --> 00:14:43.780
So this shoulder is going to be a little bit more in, which means that body is

240
00:14:43.780 --> 00:14:46.000
going to have to be rotated inside bend.

241
00:14:46.000 --> 00:14:51.000
If the shoulder is more this way, it would be very hard to have that extension.

242
00:14:51.000 --> 00:14:53.890
I'm kind of fighting two different chains that way and just feels like I'm

243
00:14:53.890 --> 00:14:56.000
making a big stretch. It doesn't feel strong.

244
00:14:56.000 --> 00:15:02.320
This is helpful for looking at my power source of chop first turn, or how early

245
00:15:02.320 --> 00:15:05.000
, really cast first turn.

246
00:15:05.000 --> 00:15:09.730
How much I've done face open versus face close, this going this way is a closer

247
00:15:09.730 --> 00:15:12.000
, this going this way is an opener.

248
00:15:12.000 --> 00:15:16.010
And then obviously it helps balance the steeps and shallows and move the low

249
00:15:16.010 --> 00:15:17.000
point around.

250
00:15:17.000 --> 00:15:21.100
The more that I do this, it shallows things out and moves the low point

251
00:15:21.100 --> 00:15:23.000
actually earlier or backward.

252
00:15:23.000 --> 00:15:27.000
And the more I do this, it will tend to steepen things but move the low point,

253
00:15:27.000 --> 00:15:32.000
very old tend to close the face but move the low point further down the swing.

254
00:15:32.000 --> 00:15:36.000
So this is the classic flexion extension graph.

255
00:15:36.000 --> 00:15:41.000
In AMM, negative extension positive is flexion.

256
00:15:41.000 --> 00:15:46.190
So start with a little flex or start with a little extend, extend towards the

257
00:15:46.190 --> 00:15:51.430
backswing, increase that 10 to 15 degrees and then release it starting about

258
00:15:51.430 --> 00:15:52.000
shaft parallel.

259
00:15:52.000 --> 00:15:58.000
This pattern here is a big part of what creates the look of lag.

260
00:15:58.000 --> 00:16:04.360
So we'll see with Ron, who we looked at in the last class, who was increasing

261
00:16:04.360 --> 00:16:08.000
his radial deviation of the lead wrist but looked like he had a cast.

262
00:16:08.000 --> 00:16:11.000
What do you think this is going to look like?

263
00:16:11.000 --> 00:16:16.760
Okay, so now we've got Henry Sensen, very similar pattern, a little bit more of

264
00:16:16.760 --> 00:16:21.000
a float because it goes up and then down.

265
00:16:21.000 --> 00:16:25.000
And then even more of a float here with Elkington.

266
00:16:25.000 --> 00:16:30.140
So this movement here where it goes up and then down will tend to look really

267
00:16:30.140 --> 00:16:36.340
more float-loady compared to someone like Grant Waite where it's just kind of a

268
00:16:36.340 --> 00:16:38.000
plateau going into that.

269
00:16:38.000 --> 00:16:42.000
Great, so TPI says to watch out for chicken wing and scooping.

270
00:16:42.000 --> 00:16:46.000
This is a big one for scooping, but this is also a big one for casting.

271
00:16:46.000 --> 00:16:49.000
We're going to see this with our three amateurs.

272
00:16:49.000 --> 00:16:54.000
You rarely see this pattern with your higher handicap golfers.

273
00:16:54.000 --> 00:16:57.000
You'll see what they do instead.

274
00:16:57.000 --> 00:17:01.550
So this relates to clubface control as well as low point control, but it also

275
00:17:01.550 --> 00:17:07.000
relates to the wipe and power and kind of managing the width of the swing.

276
00:17:07.000 --> 00:17:11.000
This is a big component for low point control and managing width.

277
00:17:11.000 --> 00:17:13.000
So now we got Colin.

278
00:17:13.000 --> 00:17:19.000
He starts with that trail wrist like under because he's in a stronger position.

279
00:17:19.000 --> 00:17:22.000
That's okay, he's either here or there.

280
00:17:22.000 --> 00:17:27.000
But when he gets to the top of the swing, you'll see he never increases.

281
00:17:27.000 --> 00:17:31.000
He doesn't have that dip that we saw with the pros.

282
00:17:31.000 --> 00:17:36.080
Let's see what that looks like, and it's a little tricky to see it from just

283
00:17:36.080 --> 00:17:37.000
one view.

284
00:17:37.000 --> 00:17:41.000
So just in case we'll bring these both up here.

285
00:17:41.000 --> 00:17:46.060
Okay, so here we can see, you know, he's 10 degrees flexed under, something

286
00:17:46.060 --> 00:17:47.000
like that.

287
00:17:47.000 --> 00:17:51.000
Gets up towards the top of the swing.

288
00:17:51.000 --> 00:17:57.570
Right in there is where we should have been increasing the extension and he's

289
00:17:57.570 --> 00:18:00.000
already starting to release it.

290
00:18:00.000 --> 00:18:07.060
So you can see at this point here, this is kind of a good little checkpoint

291
00:18:07.060 --> 00:18:09.000
where you can see how much wrist extension.

292
00:18:09.000 --> 00:18:14.600
And then if you compare it, you can see right around here, if we can imagine he

293
00:18:14.600 --> 00:18:19.000
's got a little bit more extension of the wrist than he does there.

294
00:18:19.000 --> 00:18:27.000
He gets a little bit there, but then not a whole lot.

295
00:18:27.000 --> 00:18:33.090
So if we take a look at that now, so that's what we were seeing where it wasn't

296
00:18:33.090 --> 00:18:38.000
really extending maybe a little bit of blip there and then releasing it.

297
00:18:38.000 --> 00:18:44.000
Now he didn't have a major scoop, so it was like less extended.

298
00:18:44.000 --> 00:18:49.340
We're sorry, more extended than it was at setup. It was less flexed, but it

299
00:18:49.340 --> 00:18:54.000
didn't have kind of that downswing load pattern.

300
00:18:54.000 --> 00:18:59.510
We'll see others where it's where it's a true scoop, where it's more like the

301
00:18:59.510 --> 00:19:04.000
line is crossing impact higher than where it was at setup.

302
00:19:04.000 --> 00:19:06.000
For example, this one's pretty close.

303
00:19:06.000 --> 00:19:11.130
We can see this golfer Mike is getting set up with a slight extension goes to

304
00:19:11.130 --> 00:19:12.000
the top.

305
00:19:12.000 --> 00:19:17.000
And part of the reason he can't increase it is because if we look at the scale,

306
00:19:17.000 --> 00:19:23.000
they were around 50, 55 degrees at the top, so they had room to go into more

307
00:19:23.000 --> 00:19:24.000
extension.

308
00:19:24.000 --> 00:19:26.000
He's already at 70 degrees at the top.

309
00:19:26.000 --> 00:19:32.000
He would need incredibly flexible wrist, or probably missing a ligament or two

310
00:19:32.000 --> 00:19:33.000
in order to increase it there.

311
00:19:33.000 --> 00:19:37.920
Part of what we would want to work on would be loading less in the backswing

312
00:19:37.920 --> 00:19:40.000
and more in the downswing.

313
00:19:40.000 --> 00:19:46.000
And then we can see firing-wise, he's pretty close to where he was at setup.

314
00:19:46.000 --> 00:19:52.940
Let's see, as he starts right there, a very slight extension goes up towards

315
00:19:52.940 --> 00:19:54.000
the top.

316
00:19:54.000 --> 00:19:59.000
This will be easier to see the top position from the down line.

317
00:19:59.000 --> 00:20:02.000
Pretty good extension.

318
00:20:02.000 --> 00:20:05.990
And then this is a common place down here where I'm looking for it to be

319
00:20:05.990 --> 00:20:07.000
reaching its max.

320
00:20:07.000 --> 00:20:13.040
So I'm looking for some of that wrist increasing through there, and we're just

321
00:20:13.040 --> 00:20:18.000
not seeing a whole lot of change.

322
00:20:18.000 --> 00:20:23.010
So he's getting a lot more of that hand action working more vertically as we

323
00:20:23.010 --> 00:20:24.000
look here.

324
00:20:24.000 --> 00:20:32.000
And then as we go to impact, if we just compare, there's the wrist angle.

325
00:20:32.000 --> 00:20:35.000
If we go down to impact, we can see it's about the same.

326
00:20:35.000 --> 00:20:39.000
That's pretty much what we were seeing graphically.

327
00:20:39.000 --> 00:20:42.000
Not a huge flip-like.

328
00:20:42.000 --> 00:20:46.000
From here, you'd be able to see some golfers who flip on the way through.

329
00:20:46.000 --> 00:20:49.000
You'd be able to see the wrist more in that position.

330
00:20:49.000 --> 00:20:51.000
This is still pretty neutral.

331
00:20:51.000 --> 00:20:56.000
But definitely more in that cast scoop pattern.

332
00:20:56.000 --> 00:20:57.000
And then run.

333
00:20:57.000 --> 00:21:00.000
This is now where the cast starts to show up.

334
00:21:00.000 --> 00:21:06.290
You can see that when we were looking at radial, he had a big kind of downcock

335
00:21:06.290 --> 00:21:08.000
early in transition.

336
00:21:08.000 --> 00:21:12.000
When we look at trail wrist flexion extension, it doesn't match.

337
00:21:12.000 --> 00:21:16.000
This is what gives the look of more of a cast.

338
00:21:16.000 --> 00:21:19.000
So keep that in the back of your mind.

339
00:21:19.000 --> 00:21:21.000
So we go up to the top.

340
00:21:21.000 --> 00:21:24.000
He's got some amount of extension there.

341
00:21:24.000 --> 00:21:29.000
We're looking for it to increase.

342
00:21:29.000 --> 00:21:32.000
It doesn't really increase through there.

343
00:21:32.000 --> 00:21:40.000
Let's take a look from this view.

344
00:21:40.000 --> 00:21:46.000
So right there, it has a look of more of a cast, even though we saw from the

345
00:21:46.000 --> 00:21:47.000
lead wrist

346
00:21:47.000 --> 00:21:52.000
radial graph that he was increasing the amount of hinge.

347
00:21:52.000 --> 00:21:57.000
So we can see trail arm elbow is, or sorry, lead elbow is straightening.

348
00:21:57.000 --> 00:22:02.000
That'll override some of this hinge and trail wrist is going this way.

349
00:22:02.000 --> 00:22:06.690
So as the wrist is going that way and this is straightening, that's going to

350
00:22:06.690 --> 00:22:10.000
create this width look from this face on camera.

351
00:22:10.000 --> 00:22:12.000
And then let's just see.

352
00:22:12.000 --> 00:22:16.000
So through impact, he was definitely, he's a little more if I put that.

353
00:22:16.000 --> 00:22:18.000
He's a little more extended.

354
00:22:18.000 --> 00:22:22.000
So he won't look like he has quite as much of a scoop.

355
00:22:22.000 --> 00:22:26.000
He's got a little bit of extension there.

356
00:22:26.000 --> 00:22:30.000
A little bit more compared to where he was there at setup.

357
00:22:30.000 --> 00:22:36.090
So that helps him with his consistency, but without that downswing loading, he

358
00:22:36.090 --> 00:22:38.000
's going to complain of distance all day long.

359
00:22:38.000 --> 00:22:39.000
Okay.

360
00:22:39.000 --> 00:22:42.410
So the flexion extension of the trail wrist, I think, is the by far the most

361
00:22:42.410 --> 00:22:44.000
important trail wrist graph.

362
00:22:44.000 --> 00:22:48.240
You'll see that the rest of them do give some good information, but they're

363
00:22:48.240 --> 00:22:52.000
also a little trickier to interpret.

364
00:22:52.000 --> 00:22:56.000
Typically, because of what's going on at the shoulder bend at the elbow.

365
00:22:56.000 --> 00:22:59.000
So radial ulnar graph.

366
00:22:59.000 --> 00:23:03.000
This one, again, it's really easy with AMM.

367
00:23:03.000 --> 00:23:05.000
You're kind of picking these two points.

368
00:23:05.000 --> 00:23:09.160
And so getting those vertical, it's easy to be off by five or ten degrees on

369
00:23:09.160 --> 00:23:10.000
this one.

370
00:23:10.000 --> 00:23:13.000
So don't just fall in love with certain numbers.

371
00:23:13.000 --> 00:23:17.380
But we're going to have about 20 degrees of hinge in the backswing, which is

372
00:23:17.380 --> 00:23:21.000
interesting considering we had double that with the lead wrist.

373
00:23:21.000 --> 00:23:25.000
Now, remember, the grip is typically at slightly different angles.

374
00:23:25.000 --> 00:23:29.790
So we wouldn't expect them to mirror a hundred percent, but it's about half

375
00:23:29.790 --> 00:23:33.000
what we see with the lead wrist.

376
00:23:33.000 --> 00:23:35.000
Maybe in a little less.

377
00:23:35.000 --> 00:23:41.260
And I think a lot of that comes more from going into extension than it does

378
00:23:41.260 --> 00:23:43.000
from true hinge.

379
00:23:43.000 --> 00:23:47.000
So unhinging through impact and the follow through.

380
00:23:47.000 --> 00:23:51.660
It's rare that you would see someone come out of it, but you'll see kind of

381
00:23:51.660 --> 00:23:55.000
more of a quicker drop sometimes.

382
00:23:55.000 --> 00:24:00.600
It's rare that you'll see a true ulnar show up here, partly because a lot of

383
00:24:00.600 --> 00:24:05.500
what I call ulnar when I'm looking at video is some stuff going on at the

384
00:24:05.500 --> 00:24:06.000
shoulder.

385
00:24:06.000 --> 00:24:11.210
So if you keep this wrist angle and you kind of go into more internal rotation

386
00:24:11.210 --> 00:24:15.000
and bend of the shoulder, it will narrow and start pulling things up.

387
00:24:15.000 --> 00:24:20.400
And the idea of getting that ulnar is to get that tricep more involved instead

388
00:24:20.400 --> 00:24:25.870
of that bicep and get the shoulder external rotators holding on instead of the

389
00:24:25.870 --> 00:24:29.000
internal rotators kind of flipping it through.

390
00:24:29.000 --> 00:24:32.000
But here's kind of a classic pattern.

391
00:24:32.000 --> 00:24:36.230
The thing that I identified or I noticed the most when I first started studying

392
00:24:36.230 --> 00:24:40.440
this graph was this little double peak that a lot of golfers have. That's part

393
00:24:40.440 --> 00:24:41.000
of the wipe.

394
00:24:41.000 --> 00:24:45.800
So the wipe either comes from kind of like this movement across your body

395
00:24:45.800 --> 00:24:50.820
happening at the wrist or the movement of the lead shoulder, or oftentimes both

396
00:24:50.820 --> 00:24:51.000
.

397
00:24:51.000 --> 00:24:56.810
So again, we can look at what's going on in the thorax position as well as the

398
00:24:56.810 --> 00:25:01.200
shoulders, typically, especially with this double peak in order to have that

399
00:25:01.200 --> 00:25:04.000
white movement or that second hinge in the downswing.

400
00:25:04.000 --> 00:25:08.000
You can't lose your posture during the downswing too much.

401
00:25:08.000 --> 00:25:13.080
So the ulnar, the more you go ulnar that tends to create some shallowness, that

402
00:25:13.080 --> 00:25:17.990
tends to open the face, the more that you hinge it, that will tend to close the

403
00:25:17.990 --> 00:25:21.000
face and steepen things or narrow things.

404
00:25:21.000 --> 00:25:27.910
And oftentimes if I've got this kind of shoulder lag position where the elbow

405
00:25:27.910 --> 00:25:33.120
is leading in front, I'll tend to have a little bit more of lowering the club

406
00:25:33.120 --> 00:25:37.000
from the wrist position instead of from the shoulder position.

407
00:25:37.000 --> 00:25:54.400
Now, TBI says again, ulrus, it mostly just looks at the lead wrist looking for

408
00:25:54.400 --> 00:25:54.670
the flexion extension, but I think this one relates to the downswing loading

409
00:25:54.670 --> 00:25:58.290
and casting as not quite as much as the extension, but it's very useful for

410
00:25:58.290 --> 00:26:01.000
looking at transition and what's going on with this

411
00:26:01.000 --> 00:26:07.290
peak or double peak. So this is grant weight, the one that you've been seeing

412
00:26:07.290 --> 00:26:13.000
already. So here's extension, or sorry, radial and ulnar.

413
00:26:13.000 --> 00:26:20.310
So a little bit of radial loses a bunch of it as he gets towards the top. We'll

414
00:26:20.310 --> 00:26:23.000
pull it up and kind of see if we can identify that.

415
00:26:23.000 --> 00:26:29.420
And then goes into a little bit more of this ulnar early, radial late and then

416
00:26:29.420 --> 00:26:34.000
ulnar through the ball peeking well after impact.

417
00:26:34.000 --> 00:26:40.950
It's also a little hard because the swings from 2012 weren't as high quality,

418
00:26:40.950 --> 00:26:42.000
high def.

419
00:26:42.000 --> 00:26:49.790
So remember, we're looking at the right hand. So part of that shallowness is

420
00:26:49.790 --> 00:26:55.750
the ulnar deviation, and then right in through there is where you would see the

421
00:26:55.750 --> 00:26:58.000
radial deviation increasing.

422
00:26:58.000 --> 00:27:03.930
That's kind of that white move, and you can see it when you're looking on video

423
00:27:03.930 --> 00:27:07.000
more by the trajectory of the elbow.

424
00:27:07.000 --> 00:27:12.610
If the elbow stalls and rotates, that will tend to throw that wrist out where

425
00:27:12.610 --> 00:27:19.000
if that elbow keeps leading, it's easier to keep that radial deviation.

426
00:27:19.000 --> 00:27:25.220
And then right around there is where he's maxing out that ulnar deviation of

427
00:27:25.220 --> 00:27:27.000
that trail wrist.

428
00:27:27.000 --> 00:27:34.060
But you can see it's definitely tougher to see the pattern on video than it is

429
00:27:34.060 --> 00:27:36.000
on the 3D graph.

430
00:27:36.000 --> 00:27:42.150
Okay, Henrik doesn't appear to have that same kind of double peak pattern, and

431
00:27:42.150 --> 00:27:48.000
if you look at him, he doesn't have as much of the appearance of the wipe.

432
00:27:48.000 --> 00:27:56.720
But good ulnar past it and kind of normal backswing movement. So let's just

433
00:27:56.720 --> 00:28:00.000
investigate this transition down into this place here.

434
00:28:00.000 --> 00:28:06.000
Okay, so if we take him up towards the top, we're looking at that trail wrist.

435
00:28:06.000 --> 00:28:10.940
So right about now, so you can see he has a little extra kind of downcock

436
00:28:10.940 --> 00:28:12.000
through there.

437
00:28:12.000 --> 00:28:17.100
And then right around now is where if the elbow continued and the butt of the

438
00:28:17.100 --> 00:28:22.000
club had more of a trajectory like that, you would see that double peak.

439
00:28:22.000 --> 00:28:27.740
But you'll see that his is kind of kicking out just a little bit there, and you

440
00:28:27.740 --> 00:28:33.000
can see that trail, that right elbow going into more of a rotation.

441
00:28:33.000 --> 00:28:38.860
So that elbow kind of stays on his hip and rotates, that's usually when you won

442
00:28:38.860 --> 00:28:41.000
't see that double peak.

443
00:28:41.000 --> 00:28:46.430
So that's kind of a little bit of a lack of wipe. So elk, we've got pretty

444
00:28:46.430 --> 00:28:48.000
pronounced.

445
00:28:48.000 --> 00:28:53.060
So little hinge there in the backswing, little less, little more, little less,

446
00:28:53.060 --> 00:28:58.050
little more. That's that kind of classic wipe double peak, where there's like a

447
00:28:58.050 --> 00:29:03.030
little loss during the shallowing and then a little increase as the shoulder

448
00:29:03.030 --> 00:29:04.000
works more in front.

449
00:29:04.000 --> 00:29:09.970
And then there's the release down at the bottom. Okay, so little increase,

450
00:29:09.970 --> 00:29:17.000
little decrease, little increase, and then the release.

451
00:29:17.000 --> 00:29:27.000
Again, a little tricky to see it all as clearly on 2D as we could on 3D.

452
00:29:27.000 --> 00:29:33.360
This is where looking at the trail. So there's right there's a little decrease,

453
00:29:33.360 --> 00:29:35.000
and then right around.

454
00:29:35.000 --> 00:29:39.230
Sorry, it was lightning. Right there's a little decrease as it shallows, and

455
00:29:39.230 --> 00:29:43.890
then right there is a little increase as the butt of the club is still being

456
00:29:43.890 --> 00:29:46.000
accelerated around his body.

457
00:29:46.000 --> 00:29:51.000
And then there's kind of where it reaches maximum right around there.

458
00:29:51.000 --> 00:29:57.500
Okay, so this one for amateurs, I'll show you the common pattern that you'll

459
00:29:57.500 --> 00:29:58.000
see.

460
00:29:58.000 --> 00:30:04.000
It's usually either a little bit more increased in the backswing or more of

461
00:30:04.000 --> 00:30:08.200
closer what we saw with Henrik Stenson, because more amateurs tend to lack that

462
00:30:08.200 --> 00:30:10.000
wipe or that second peak.

463
00:30:10.000 --> 00:30:15.140
So it's related to the power source, but it's highly related to the club face

464
00:30:15.140 --> 00:30:18.000
control and low point or path control.

465
00:30:18.000 --> 00:30:23.770
So again, I use this one more for what's going on in transition, so I actually

466
00:30:23.770 --> 00:30:28.000
don't really think this is as relevant for the chicken wing scooping.

467
00:30:28.000 --> 00:30:33.760
It's more about the power source and the wipe and what's going on as they blend

468
00:30:33.760 --> 00:30:39.000
from the late transition into early downswing or early release.

469
00:30:39.000 --> 00:30:45.910
So here we got Colin, so hinges 30 degrees there and then an additional 20

470
00:30:45.910 --> 00:30:47.000
degrees.

471
00:30:47.000 --> 00:30:50.890
So this is common where you see the amateur really hinging that wrist up

472
00:30:50.890 --> 00:30:55.000
because they're trying to create more of this vertical chop pattern.

473
00:30:55.000 --> 00:31:02.840
So he increases during that whole downswing, but part of that is probably if I

474
00:31:02.840 --> 00:31:08.000
keep my wrist in this position and then I bring my elbow up,

475
00:31:08.000 --> 00:31:13.390
I can feel a little increased tension or if I bring my elbow out, like if I

476
00:31:13.390 --> 00:31:17.000
start to go into internal rotation like this,

477
00:31:17.000 --> 00:31:22.000
I can feel a little increased movement or tension in that wrist going up.

478
00:31:22.000 --> 00:31:27.300
So you'll tend to see this either with golfers where that elbow gets behind or

479
00:31:27.300 --> 00:31:32.000
if they're kind of rotating downward.

480
00:31:32.000 --> 00:31:37.000
But then he does get it to peak well after impact.

481
00:31:37.000 --> 00:31:42.000
Like I said, these tend to not be quite as clear.

482
00:31:42.000 --> 00:31:49.000
You will often see golfers with kind of a more of a steep pattern.

483
00:31:49.000 --> 00:31:51.000
We'll tend to have this lower at impact.

484
00:31:51.000 --> 00:31:58.060
I didn't really highlight that it's usually around the same location at impact

485
00:31:58.060 --> 00:32:00.000
as of where it was at setup or just a little bit less.

486
00:32:00.000 --> 00:32:06.400
Some amperatures will be way down there where they basically get kind of a

487
00:32:06.400 --> 00:32:13.230
steep kind of late over type pattern where that wrist is just never coming out

488
00:32:13.230 --> 00:32:15.000
of the radial deviation.

489
00:32:15.000 --> 00:32:21.370
So just to show, since I forgot to highlight that, here we've got more owner

490
00:32:21.370 --> 00:32:24.000
deviated at impact.

491
00:32:24.000 --> 00:32:29.000
And then here we've got about the same, slightly more owner deviated at impact.

492
00:32:29.000 --> 00:32:34.050
And then here we've got about the same, just a little less, but it's usually

493
00:32:34.050 --> 00:32:41.000
pretty close with the amateurs calling way down here, right?

494
00:32:41.000 --> 00:32:49.000
That's where we'll see that pretty clearly here from the down the line.

495
00:32:49.000 --> 00:32:53.000
So here he's got that big hinge at the top.

496
00:32:53.000 --> 00:32:58.000
And then it's just kind of gradually, or it's increasing through there.

497
00:32:58.000 --> 00:33:04.170
And then gradually releasing, but down at impact, you can see kind of that

498
00:33:04.170 --> 00:33:09.420
angle, that wrist is still kind of hinged up a little bit more, it hasn't gone

499
00:33:09.420 --> 00:33:10.000
fully this way.

500
00:33:10.000 --> 00:33:16.740
One of the telltale signs, you'll see the club kind of like swing up and around

501
00:33:16.740 --> 00:33:19.000
compared to the wrist.

502
00:33:19.000 --> 00:33:25.190
It can be like under over the top, but compared to the wrist, it's just not in

503
00:33:25.190 --> 00:33:26.000
line.

504
00:33:26.000 --> 00:33:34.060
So Mike Mullins, again, 20 degrees or so, increases it even more, doesn't

505
00:33:34.060 --> 00:33:37.000
really have that second peak.

506
00:33:37.000 --> 00:33:44.000
And then crosses impact lower, not as bad, but definitely lower.

507
00:33:44.000 --> 00:33:50.000
So downswing, here we've got the really big wrist set.

508
00:33:50.000 --> 00:33:58.040
And then as that shoulder starts to work, that elbow staying high, the wrist is

509
00:33:58.040 --> 00:34:02.650
increasing its radial deviation, and then right around there, it's starting to

510
00:34:02.650 --> 00:34:04.000
come out.

511
00:34:04.000 --> 00:34:09.910
Again, closer to in line with that right forearm, but still a little bit more

512
00:34:09.910 --> 00:34:15.990
kind of like rotating over like this instead of getting closer to full ulnar,

513
00:34:15.990 --> 00:34:18.000
like we saw closer what we saw with the pros.

514
00:34:18.000 --> 00:34:23.000
And then run, runs, trail wrist actually has some of the elements.

515
00:34:23.000 --> 00:34:28.360
Again, he's kind of weak because of that trail wrist flexion and the power

516
00:34:28.360 --> 00:34:33.000
source of the way he uses his body, but crosses a little bit lower.

517
00:34:33.000 --> 00:34:39.000
And doesn't have a massive hinge, that's a little more consistent pattern.

518
00:34:39.000 --> 00:34:43.730
Again, this one's a little trickier to see, but you can see when he goes

519
00:34:43.730 --> 00:34:51.210
through impact, closer to kind of in line with the right arm forearm down

520
00:34:51.210 --> 00:34:52.000
through there.

521
00:34:52.000 --> 00:35:06.460
That's a sign of more ulnar deviation. And right around there, if we look from

522
00:35:06.460 --> 00:35:08.000
the face on.

523
00:35:08.000 --> 00:35:12.540
So right here is where you would tend to see the lack of wipe, but he actually

524
00:35:12.540 --> 00:35:16.780
keeps that elbow moving a little bit, and then it's just kind of right down

525
00:35:16.780 --> 00:35:20.990
there that he tends to stall out that elbow movement and go more from the

526
00:35:20.990 --> 00:35:22.000
shoulder.

527
00:35:22.000 --> 00:35:23.000
Not bad.

528
00:35:23.000 --> 00:35:34.510
Okay, last and most confusing is the pronation supination graph on the trail

529
00:35:34.510 --> 00:35:37.350
wrist. And you'll see the trail wrist pronation or the trail forearm pronation

530
00:35:37.350 --> 00:35:39.000
supination, you battle a lot of trying to decode what's happening at the wrist

531
00:35:39.000 --> 00:35:41.000
actively and what's happening at the shoulder.

532
00:35:41.000 --> 00:35:46.620
But roughly the baseline pattern you'll see is somewhere around 40 degrees sup

533
00:35:46.620 --> 00:35:51.440
inated at set up. That's partly because of what's going on at the shoulder,

534
00:35:51.440 --> 00:35:59.000
right? So if I'm supinated like this, then in order to get that elbow on the

535
00:35:59.000 --> 00:36:03.000
club, it's going to be a little bit more in this position there.

536
00:36:03.000 --> 00:36:07.770
So some golfers, you'll see it at like 90 if their arm is like way out like

537
00:36:07.770 --> 00:36:14.410
this, or higher, like 90, but you know, 75, 80, pronate approximately 10

538
00:36:14.410 --> 00:36:16.000
degrees at the top.

539
00:36:16.000 --> 00:36:23.950
And then the big one is kind of seeing it continue pronating. So here's where

540
00:36:23.950 --> 00:36:27.000
this all gets tricky.

541
00:36:27.000 --> 00:36:32.280
That'll be pretty clear there. So the more, the more, if I bring my elbow out

542
00:36:32.280 --> 00:36:38.300
this way, my forearm is supinating. It's the same thing graphically as if I did

543
00:36:38.300 --> 00:36:39.000
this.

544
00:36:39.000 --> 00:36:44.620
If I bring my elbow in, and this doesn't move, this is pronating. It's the same

545
00:36:44.620 --> 00:36:49.460
thing as going like this. So oftentimes, because if I, if I went here and I

546
00:36:49.460 --> 00:36:52.000
just pronated, that's going to steepen the shaft.

547
00:36:52.000 --> 00:36:57.700
But what I've seen is if the elbow starts working in front, you'll see that

548
00:36:57.700 --> 00:36:59.000
line change.

549
00:36:59.000 --> 00:37:03.910
So this dip after the top of the swing is kind of a sign that they're getting

550
00:37:03.910 --> 00:37:09.440
some shoulder external rotation because I promise you they're not actually pron

551
00:37:09.440 --> 00:37:14.000
ating and steepening the shaft. They're in transition.

552
00:37:14.000 --> 00:37:28.380
And then the other one is supination. So with how, with most golfers on the

553
00:37:28.380 --> 00:37:29.200
grip like this, supination would have more of a look of shallowing like this.

554
00:37:29.200 --> 00:37:31.000
But if I start to go this way, it's also going to have a look of supination on

555
00:37:31.000 --> 00:37:31.000
the graph.

556
00:37:31.000 --> 00:37:37.360
So you, you can't tell just from the graph if they're getting like a good shaft

557
00:37:37.360 --> 00:37:43.000
lowering, or if they're getting a poor trail arm wipe movement.

558
00:37:43.000 --> 00:37:48.120
But typically with the pros, because they're doing that, that shallowing

559
00:37:48.120 --> 00:37:52.410
movement, you'll tend to see it supinate until very close to impact where oft

560
00:37:52.410 --> 00:37:56.000
entimes with the amateurs, it'll start protein pronating sooner.

561
00:37:56.000 --> 00:38:01.280
Because they kind of run out of shoulder room and then the forearm kicks in and

562
00:38:01.280 --> 00:38:03.000
turns over even more.

563
00:38:03.000 --> 00:38:07.350
So this one, looking at what's happening in the shoulder is critical for trying

564
00:38:07.350 --> 00:38:12.010
to understand this graph. And even then it's a little bit tricky. But you also

565
00:38:12.010 --> 00:38:18.030
want to look at the thorax position to see, you know, what's likely happening

566
00:38:18.030 --> 00:38:19.000
at the shoulder.

567
00:38:19.000 --> 00:38:22.400
What's the shoulder blade doing? What's the glenohumeral joint doing? That'll

568
00:38:22.400 --> 00:38:25.000
help you figure out what the forearm might be doing.

569
00:38:25.000 --> 00:38:31.000
So this one, the steep shallows and the open clothes, this is a huge component.

570
00:38:31.000 --> 00:38:35.710
And then a little bit of the power, because if I get that elbow working in,

571
00:38:35.710 --> 00:38:39.000
that allows me to be more rotational power wise.

572
00:38:39.000 --> 00:38:43.000
So it is related to that as well.

573
00:38:43.000 --> 00:38:48.360
I think, again, this is a big one to look at, transition, and then it's tricky

574
00:38:48.360 --> 00:38:54.780
to infer how it's relating the scoop chicken wing. In theory, I would say that

575
00:38:54.780 --> 00:39:00.000
more of the scoop chicken wing is happening from flexion extension or going

576
00:39:00.000 --> 00:39:06.180
into lack of older deviation, not so much what's happening at the forearm sup

577
00:39:06.180 --> 00:39:08.000
ination, or forearm pronation.

578
00:39:08.000 --> 00:39:13.140
But I do tend to teach more of this forearm pronation, even though the graph

579
00:39:13.140 --> 00:39:19.000
doesn't really show it adamantly, because of what's happening at the shoulder.

580
00:39:19.000 --> 00:39:23.610
So I tend to teach more of that kind of stop sign position, or like this

581
00:39:23.610 --> 00:39:28.790
shoulder is still an external rotation, forearm is older deviated, a little

582
00:39:28.790 --> 00:39:34.480
extended, kind of getting into that good position there. That's pretty much

583
00:39:34.480 --> 00:39:40.000
that position that I like to see in the follow through for a lot of golfers.

584
00:39:40.000 --> 00:39:48.330
Okay, so now we've got grant weight. Again, little bit of supination in the

585
00:39:48.330 --> 00:39:54.220
takeaway pronation to start the downswing, or to end the backswing, and then

586
00:39:54.220 --> 00:39:57.000
continue to start the downswing.

587
00:39:57.000 --> 00:40:00.670
So that should look like it's steepening, but we know that what's happening at

588
00:40:00.670 --> 00:40:04.290
the shoulder, that's going to be more of a shallowing movement, and then sup

589
00:40:04.290 --> 00:40:08.090
ination for the majority of the downswing, and then haven't totally figured out

590
00:40:08.090 --> 00:40:13.000
why we always see this little double peak, but that's pretty classic.

591
00:40:13.000 --> 00:40:20.880
Double peak right around impact before going into that pronation through to the

592
00:40:20.880 --> 00:40:27.580
finish. Okay, so let's just look at that one little piece. So right here, right

593
00:40:27.580 --> 00:40:36.560
there is where, if you're looking at kind of the two joints there, or the two

594
00:40:36.560 --> 00:40:39.000
bones there, compared to the elbow,

595
00:40:39.000 --> 00:40:46.950
you will see elbow points more down, and this bone is getting a little bit more

596
00:40:46.950 --> 00:40:54.060
on top. That's the pronation that we're seeing, and that's being driven from

597
00:40:54.060 --> 00:40:58.000
the elbow leading that movement.

598
00:40:58.000 --> 00:41:03.520
I should say, creating the external rotation at the shoulder, which creates the

599
00:41:03.520 --> 00:41:09.100
leading of the elbow to the wrist. So it's weird, but typically golfers who

600
00:41:09.100 --> 00:41:15.000
steepen the shaft will look like they are shallowing it from the pure wrist.

601
00:41:15.000 --> 00:41:19.580
It looks like they're supinating, and golfers who shallow it will look like

602
00:41:19.580 --> 00:41:24.500
they're steepening. So here's a similar pattern for Henrik going up to the top,

603
00:41:24.500 --> 00:41:29.680
and then good shallow movement there, even though it says steepening, and then

604
00:41:29.680 --> 00:41:32.000
good supination, double peak.

605
00:41:32.000 --> 00:41:37.360
Let's look at this last one. So Elkington, again, he's a little later, so he

606
00:41:37.360 --> 00:41:42.710
has kind of that steeper movement early, just a little bit of kind of shallow,

607
00:41:42.710 --> 00:41:46.000
late kind of steep pull down, just a touch.

608
00:41:46.000 --> 00:41:51.700
And so, again, it looks like it should be doing the opposite because of what's

609
00:41:51.700 --> 00:41:54.000
happening at the shoulder.

610
00:41:54.000 --> 00:41:58.790
Okay, again, the errors are largely related to the steep shallows and the club

611
00:41:58.790 --> 00:42:03.450
face control when we're looking at the hands, but I would say that this is just

612
00:42:03.450 --> 00:42:08.020
as much a transition discussion as it is an impact scooping and chicken wing

613
00:42:08.020 --> 00:42:09.000
pattern.

614
00:42:09.000 --> 00:42:14.190
So this is more classic, what you'll see, so Colin looks like he's just sup

615
00:42:14.190 --> 00:42:19.720
inating the entire downswing, which would be going this way, but that's also

616
00:42:19.720 --> 00:42:25.000
because he's going that way with the shoulder, the entire downswing.

617
00:42:25.000 --> 00:42:31.390
So you'll see Elbow going out, Elbow going out, you can see that the forearm is

618
00:42:31.390 --> 00:42:37.990
supinating, but you can also see that the shaft is kind of steepening through

619
00:42:37.990 --> 00:42:43.680
there, and then it is shallowing, which you can, if you look at the forearm,

620
00:42:43.680 --> 00:42:47.000
you can see that it is supinating

621
00:42:47.000 --> 00:42:53.740
that whole time, partly to account for the shoulder being in more of a steep

622
00:42:53.740 --> 00:43:00.730
position, because if that actually pronated in that position, club would be

623
00:43:00.730 --> 00:43:04.000
very vertical, Charles Barkley ish.

624
00:43:04.000 --> 00:43:08.000
Not that it isn't vertical, but he's at least working away from it.

625
00:43:08.000 --> 00:43:14.240
Mike Mullins, similar pattern, they kind of have similar issues, you'll see he

626
00:43:14.240 --> 00:43:20.420
's got a little bit more of that double peak, but so you'll see that Elbow stay

627
00:43:20.420 --> 00:43:26.120
out, so because there's not a lot of shoulder external rotation, and there's a

628
00:43:26.120 --> 00:43:30.000
lot more kind of shoulder dynamic firing.

629
00:43:30.000 --> 00:43:35.570
You can see the shoulder blade is kind of going into more protraction, that arm

630
00:43:35.570 --> 00:43:41.330
is starting to straighten pretty early, those would indicate that the shoulder

631
00:43:41.330 --> 00:43:46.870
is going to be going more this way, going into that rotation, and that's going

632
00:43:46.870 --> 00:43:53.000
to show up as supination, if the all things stayed equal at the hand.

633
00:43:53.000 --> 00:44:01.010
Last but not least, got run, again, he gets a little bit shallower, but not

634
00:44:01.010 --> 00:44:09.160
great, not as dynamic or not as big of a movement as what we saw with the pros,

635
00:44:09.160 --> 00:44:13.680
so a little bit of elbow leading, kind of through there, like you don't see the

636
00:44:13.680 --> 00:44:18.490
shoulder really getting thrown that way, but we know from what's happening at

637
00:44:18.490 --> 00:44:20.000
the wrist that it's still a cast pattern.

638
00:44:20.000 --> 00:44:25.180
Just not, he's got better shoulder mechanics, and that tends to show up here as

639
00:44:25.180 --> 00:44:30.530
a little bit better pronation supination pattern, but this is probably, I would

640
00:44:30.530 --> 00:44:35.900
say, the toughest of the graphs to interpret because they look similar, whether

641
00:44:35.900 --> 00:44:40.630
you do the classic amateur, or whether you do the classic pro, there's some

642
00:44:40.630 --> 00:44:42.000
little differences to work through.

643
00:44:42.000 --> 00:44:46.670
The biggest one for the trail wrist is looking at the flexion extension,

644
00:44:46.670 --> 00:44:51.190
because I've yet to see a really great ball striker who didn't have this

645
00:44:51.190 --> 00:44:56.000
pattern, and I've yet to see a really poor ball striker who had this pattern.

646
00:44:56.000 --> 00:45:00.690
So, working on that throwers catch or downswing loading can be really helpful

647
00:45:00.690 --> 00:45:04.780
if you're comfortable doing that. You can also look at what's going on at the

648
00:45:04.780 --> 00:45:08.280
wipe, and then a little bit of the shallowing movement from that pronation sup

649
00:45:08.280 --> 00:45:09.000
ination.

650
00:45:09.000 --> 00:45:14.360
So there is a lot of important information that you can glean from this graph,

651
00:45:14.360 --> 00:45:18.870
but you do have to look at what's going on at the shoulder in order to

652
00:45:18.870 --> 00:45:22.000
interpret some of these key movements.

653
00:45:22.000 --> 00:45:26.940
You can see a relatively similar pattern here for the stock toward model, and

654
00:45:26.940 --> 00:45:32.020
then we can see some of the big differences, especially with this green, green

655
00:45:32.020 --> 00:45:37.030
line, and the blue line in transition, a little bit of the timing of the red

656
00:45:37.030 --> 00:45:39.000
piece.

657
00:45:39.000 --> 00:45:42.830
So, hopefully this helps the series helps you feel a lot more comfortable

658
00:45:42.830 --> 00:45:46.970
looking at these graphs and thinking about these not just isolated movements,

659
00:45:46.970 --> 00:45:50.000
but how they relate to the movement system as a whole.

660
00:45:50.000 --> 00:45:54.790
If you have any questions, then please let us know, comment below, and we will

661
00:45:54.790 --> 00:45:57.000
get a clarification out for you.

662
00:45:57.000 --> 00:46:01.000
But hopefully this makes you a lot more confident when you're looking at video,

663
00:46:01.000 --> 00:46:05.190
or if you're looking at 3D graphs to understand what a segment is doing, what

664
00:46:05.190 --> 00:46:09.210
should it be doing, what phases it working in, and how does it relate to the

665
00:46:09.210 --> 00:46:11.000
overall movement system as a whole.

666
00:46:11.000 --> 00:46:14.970
So, until next time, let me know if you have any questions about these

667
00:46:14.970 --> 00:46:18.000
movements, otherwise happy golfing coaches.
