Driver Vs Iron Presentation

WEBVTT

1
00:00:00.000 --> 00:00:04.720
Hi, I'm Tyler Farrell with Golf Smart Academy.

2
00:00:04.720 --> 00:00:09.570
The topic is looking at the 3D differences between the driver and the iron

3
00:00:09.570 --> 00:00:10.280
swing.

4
00:00:10.280 --> 00:00:13.280
Basically addressing the question, is there one swing that you can use

5
00:00:13.280 --> 00:00:14.000
throughout the

6
00:00:14.000 --> 00:00:18.360
bag or do you need to make adjustments to your swing other than just set up

7
00:00:18.360 --> 00:00:19.000
when you're

8
00:00:19.000 --> 00:00:22.400
going from, say, a driver to a short iron?

9
00:00:22.400 --> 00:00:26.360
Now in this presentation, I'm going to break it down into two different parts.

10
00:00:26.360 --> 00:00:29.280
In the first part, we're going to look at a bunch of 3D graphs.

11
00:00:29.280 --> 00:00:33.970
So if you're a golf coach or just a 3D golf nerd and you want to see some of

12
00:00:33.970 --> 00:00:34.600
the data

13
00:00:34.600 --> 00:00:39.640
behind the concepts that I tend to teach, I'm going to present that for about

14
00:00:39.640 --> 00:00:40.760
15 minutes

15
00:00:40.760 --> 00:00:41.760
or so.

16
00:00:41.760 --> 00:00:45.220
If you want to just jump to the end, you know, if you're not really into the 3D

17
00:00:45.220 --> 00:00:45.760
space and

18
00:00:45.760 --> 00:00:48.600
you really just want to jump to the end and see some of the before and afters

19
00:00:48.600 --> 00:00:49.000
and look

20
00:00:49.000 --> 00:00:55.460
at more 2D video practical applications, I think that that's fine.

21
00:00:55.460 --> 00:00:59.950
I'll put a little link here where you can jump right to when we start looking

22
00:00:59.950 --> 00:01:00.460
at golf

23
00:01:00.460 --> 00:01:03.220
swings instead of looking at 3D graphs.

24
00:01:03.220 --> 00:01:07.610
So I'll show you how understanding some of the differences between driver and

25
00:01:07.610 --> 00:01:08.200
iron can

26
00:01:08.200 --> 00:01:10.220
help you make changes.

27
00:01:10.220 --> 00:01:16.060
So this was one individual lesson who basically by understanding a different

28
00:01:16.060 --> 00:01:17.140
pivot concept

29
00:01:17.140 --> 00:01:20.660
was able to completely change his release and ball flight.

30
00:01:20.660 --> 00:01:24.920
And then I have another example where we'll go through a golfer who was driving

31
00:01:24.920 --> 00:01:25.480
the ball

32
00:01:25.480 --> 00:01:29.380
really well but struggling with his iron play.

33
00:01:29.380 --> 00:01:33.520
Because what I've noticed with both my students as well as myself is it's rare

34
00:01:33.520 --> 00:01:34.300
that you have

35
00:01:34.300 --> 00:01:38.940
the best driver day and the best iron day on the same day.

36
00:01:38.940 --> 00:01:43.010
So in the rest of this presentation, we're going to take a look at why that

37
00:01:43.010 --> 00:01:43.580
might be

38
00:01:43.580 --> 00:01:45.220
the case.

39
00:01:45.220 --> 00:01:49.580
Before I get into the data, I interviewed a number of coaches trying to figure

40
00:01:49.580 --> 00:01:50.100
out what

41
00:01:50.100 --> 00:01:53.520
they thought might be the difference between the driver swing and the iron

42
00:01:53.520 --> 00:01:54.060
swing.

43
00:01:54.060 --> 00:01:58.550
Now some coaches continue to stress that there's no difference, it's just set

44
00:01:58.550 --> 00:01:59.020
up.

45
00:01:59.020 --> 00:02:04.870
But many golf instructors focus on the axis tilt or the position of the body

46
00:02:04.870 --> 00:02:05.580
and what

47
00:02:05.580 --> 00:02:09.860
changes during the swing with a driver and during an iron.

48
00:02:09.860 --> 00:02:13.580
Other coaches tend to focus more on what the goals are.

49
00:02:13.580 --> 00:02:17.650
So with a driver you're trying to hit for angles and you're trying to maximize

50
00:02:17.650 --> 00:02:18.260
distance

51
00:02:18.260 --> 00:02:23.630
where with an iron, you're trying to strike it solidly and control trajectory

52
00:02:23.630 --> 00:02:24.700
and proximity

53
00:02:24.700 --> 00:02:25.700
to the hole.

54
00:02:25.700 --> 00:02:30.510
Now a few biomechanists described the driver swing as more of a total body

55
00:02:30.510 --> 00:02:31.620
activity while

56
00:02:31.620 --> 00:02:35.620
the iron swing is more of an upper body activity.

57
00:02:35.620 --> 00:02:41.110
Let's look at the data and see which ones of these hypotheses the data supports

58
00:02:41.110 --> 00:02:41.460
.

59
00:02:41.460 --> 00:02:44.970
So before we jump into the data, I want to give a big thank you to Johnson-Cl

60
00:02:44.970 --> 00:02:45.500
aire for

61
00:02:45.500 --> 00:02:48.380
providing some of these tour pro folders.

62
00:02:48.380 --> 00:02:53.500
I have a lot of driver swings but he was able to share 31 different tour pro

63
00:02:53.500 --> 00:02:54.340
folders which

64
00:02:54.340 --> 00:02:59.060
had driver, five iron, a short iron whether it was eight iron through wedge as

65
00:02:59.060 --> 00:02:59.580
well as

66
00:02:59.580 --> 00:03:01.420
a 30 yard pitch shot.

67
00:03:01.420 --> 00:03:05.260
So I was able to analyze some of these patterns and see if it was more of a

68
00:03:05.260 --> 00:03:06.220
spectrum or see

69
00:03:06.220 --> 00:03:10.380
if they were the same or where it changed and come up with some theories as to

70
00:03:10.380 --> 00:03:10.900
why.

71
00:03:10.900 --> 00:03:14.050
So the first section we're going to go over the kinematic sequence, some

72
00:03:14.050 --> 00:03:15.100
positional changes

73
00:03:15.100 --> 00:03:18.880
between the upper and lower body and then some movements during the release

74
00:03:18.880 --> 00:03:19.620
specifically

75
00:03:19.620 --> 00:03:22.020
looking at supination.

76
00:03:22.020 --> 00:03:26.540
Again in the second half of this presentation you can just jump ahead and see

77
00:03:26.540 --> 00:03:27.540
some case studies

78
00:03:27.540 --> 00:03:31.990
of how we apply this 3D data because I don't necessarily think every golfer out

79
00:03:31.990 --> 00:03:32.620
there needs

80
00:03:32.620 --> 00:03:36.060
to understand the 3D data but if you're a coach it can be really helpful for

81
00:03:36.060 --> 00:03:36.580
helping

82
00:03:36.580 --> 00:03:43.700
you think about the movement patterns in a more specific way.

83
00:03:43.700 --> 00:03:47.570
So my goal is to present you with the data and visuals and let you come up with

84
00:03:47.570 --> 00:03:47.940
ways

85
00:03:47.940 --> 00:03:48.940
that you can teach it.

86
00:03:48.940 --> 00:03:52.880
I'm not here to say that there's one perfect way to adjust the swing just

87
00:03:52.880 --> 00:03:54.060
because the graphs

88
00:03:54.060 --> 00:03:59.740
are a little bit different but I want to get your brain thinking about the

89
00:03:59.740 --> 00:04:01.460
actual differences

90
00:04:01.460 --> 00:04:05.000
between the two and hopefully you can come up with some creative ways to get

91
00:04:05.000 --> 00:04:05.780
your students

92
00:04:05.780 --> 00:04:11.780
to make these changes and make it feel as seamless or athletic as possible.

93
00:04:11.780 --> 00:04:16.140
Now we know that the angle of attack tends to change throughout the bag.

94
00:04:16.140 --> 00:04:19.220
We know that with the short iron it's going to be somewhat down and with the

95
00:04:19.220 --> 00:04:19.860
driver it's

96
00:04:19.860 --> 00:04:24.620
going to be flat or even up, hopefully up if you're trying to maximize distance

97
00:04:24.620 --> 00:04:24.940
.

98
00:04:24.940 --> 00:04:30.490
One of the questions is that we've kind of struggled with is this purely a

99
00:04:30.490 --> 00:04:31.940
setup change,

100
00:04:31.940 --> 00:04:36.090
purely a equipment change or is there an intentional change to how the golfer

101
00:04:36.090 --> 00:04:37.020
is trying to swing

102
00:04:37.020 --> 00:04:38.020
the club.

103
00:04:38.020 --> 00:04:43.420
Hopefully the 3D data will shed a little light on which of these is the case.

104
00:04:43.420 --> 00:04:49.720
Now with the 3D data I took a look at a number of different parameters but in

105
00:04:49.720 --> 00:04:51.400
this presentation

106
00:04:51.400 --> 00:04:56.610
because I was limited to 45 minutes I focused on the kinematic sequence changes

107
00:04:56.610 --> 00:04:57.340
, the axis

108
00:04:57.340 --> 00:05:02.440
tilt changes which would be we'll look at the differences in the sway graphs

109
00:05:02.440 --> 00:05:03.100
and then

110
00:05:03.100 --> 00:05:06.220
the lead risk looking at supination.

111
00:05:06.220 --> 00:05:10.310
But as you can see if you want to pause this slide you can see that there were

112
00:05:10.310 --> 00:05:10.940
changes

113
00:05:10.940 --> 00:05:16.020
in what the body did in how the club worked as well as in the arms and the legs

114
00:05:16.020 --> 00:05:16.540
and if

115
00:05:16.540 --> 00:05:20.460
you have a good data set you can take a look at some of these patterns as well

116
00:05:20.460 --> 00:05:20.900
and see

117
00:05:20.900 --> 00:05:25.580
if your data matches the data that I was looking at.

118
00:05:25.580 --> 00:05:31.510
So the general change in the kinematic sequence, if you've looked at 3D and you

119
00:05:31.510 --> 00:05:32.660
've seen some

120
00:05:32.660 --> 00:05:35.980
of these 3D graphs you may be familiar with the two on screen.

121
00:05:35.980 --> 00:05:41.020
We have kind of the standard or classic full swing kinematic sequence and then

122
00:05:41.020 --> 00:05:41.600
we have

123
00:05:41.600 --> 00:05:44.580
the standard or classic 30 yard wedge shot.

124
00:05:44.580 --> 00:05:49.370
The 30 yard wedge shot has more of a fanning pattern, more of a cast pattern

125
00:05:49.370 --> 00:05:50.060
where the

126
00:05:50.060 --> 00:05:53.600
club is moving faster than the arm, arm moving faster than the torso, the torso

127
00:05:53.600 --> 00:05:54.380
moving faster

128
00:05:54.380 --> 00:05:59.360
than the pelvis even though the transition sequence is the same.

129
00:05:59.360 --> 00:06:05.210
With the full swing we see more of a downswing loading pattern so we see more

130
00:06:05.210 --> 00:06:06.720
of a lower body

131
00:06:06.720 --> 00:06:09.720
moving faster than the upper body, upper body moving faster than the arm, arm

132
00:06:09.720 --> 00:06:10.360
moving faster

133
00:06:10.360 --> 00:06:15.720
than the club to help maximize the speed gains and to potentially help with a

134
00:06:15.720 --> 00:06:16.380
little bit

135
00:06:16.380 --> 00:06:19.080
of the path requirements for the driver.

136
00:06:19.080 --> 00:06:24.190
The question is is this more of a switch where you go from driver and all your

137
00:06:24.190 --> 00:06:24.840
full swing

138
00:06:24.840 --> 00:06:28.280
should look like the top graph and then once you get to these half shots it

139
00:06:28.280 --> 00:06:28.960
switches or

140
00:06:28.960 --> 00:06:30.780
is it more of a spectrum.

141
00:06:30.780 --> 00:06:36.140
Let's take a look at some different full swing graphs to help possibly explain

142
00:06:36.140 --> 00:06:37.080
that pattern.

143
00:06:37.080 --> 00:06:41.120
Is it more of a switch or is it more of a spectrum?

144
00:06:41.120 --> 00:06:45.270
The general trend with the kinematic sequence was that the driver swing was

145
00:06:45.270 --> 00:06:46.260
more of a loading

146
00:06:46.260 --> 00:06:50.160
pattern and then the wedge swing was more of a cast pattern.

147
00:06:50.160 --> 00:06:53.980
So we'll look at a number of different examples so you can visualize what I'm

148
00:06:53.980 --> 00:06:54.760
talking about

149
00:06:54.760 --> 00:06:59.070
but while each individual golfer kept a little bit of their own signature and

150
00:06:59.070 --> 00:07:00.580
their own pattern

151
00:07:00.580 --> 00:07:04.250
you'll see from looking at these graphs that Torpros do make some subtle shifts

152
00:07:04.250 --> 00:07:05.120
to how they're

153
00:07:05.120 --> 00:07:10.270
applying energy and how they are swinging the golf club within full swings

154
00:07:10.270 --> 00:07:11.200
whether it's

155
00:07:11.200 --> 00:07:15.360
a short iron like an eight iron iron wedge or a full swing with the driver.

156
00:07:15.360 --> 00:07:18.160
It is not exactly the same pattern.

157
00:07:18.160 --> 00:07:22.520
What was interesting was Torpros pretty consistently made these changes to

158
00:07:22.520 --> 00:07:24.640
their swings where amateurs

159
00:07:24.640 --> 00:07:29.350
usually made the same swing with every club in their bag and tended to struggle

160
00:07:29.350 --> 00:07:30.020
with one

161
00:07:30.020 --> 00:07:35.560
end or the other depending on which end their pattern better matched.

162
00:07:35.560 --> 00:07:38.160
So here's how we're going to look at these graphs.

163
00:07:38.160 --> 00:07:43.540
I'm going to put up the driver and the iron version and then we're going to

164
00:07:43.540 --> 00:07:44.560
just eyeball

165
00:07:44.560 --> 00:07:45.560
some of these differences.

166
00:07:45.560 --> 00:07:48.340
I'm not going to throw a ton of numbers at you, we're just going to look at the

167
00:07:48.340 --> 00:07:48.720
general

168
00:07:48.720 --> 00:07:49.720
movement patterns.

169
00:07:49.720 --> 00:07:53.000
Now if you've never seen a kinematic sequence graph basically we have a

170
00:07:53.000 --> 00:07:53.840
timeline of the

171
00:07:53.840 --> 00:07:54.840
golf swing.

172
00:07:54.840 --> 00:07:58.960
So we have a dress, top of the swing, impact finish.

173
00:07:58.960 --> 00:08:03.170
So this is all backswing, right here is downswing and then between these two

174
00:08:03.170 --> 00:08:04.120
lines is the follow

175
00:08:04.120 --> 00:08:05.440
through.

176
00:08:05.440 --> 00:08:09.120
When a line is negative it's rotating away from the target when it's positive

177
00:08:09.120 --> 00:08:10.000
it's rotating

178
00:08:10.000 --> 00:08:11.800
towards the target.

179
00:08:11.800 --> 00:08:15.500
And what we can see is the red line is the pelvis, the green line is the thorax

180
00:08:15.500 --> 00:08:15.880
, the

181
00:08:15.880 --> 00:08:22.400
blue line is the left arm or lead arm and then the brown line is the club.

182
00:08:22.400 --> 00:08:26.730
So this particular golfer you can see is the lower body change direction when

183
00:08:26.730 --> 00:08:27.080
it went

184
00:08:27.080 --> 00:08:31.840
from negative to positive change direction here, clearly before the upper body

185
00:08:31.840 --> 00:08:32.240
then the

186
00:08:32.240 --> 00:08:35.680
upper body before the arm before the club.

187
00:08:35.680 --> 00:08:38.640
And you can see that the red line is above for part of the downswing, the blue

188
00:08:38.640 --> 00:08:39.040
line is

189
00:08:39.040 --> 00:08:40.960
above for part of the downswing.

190
00:08:40.960 --> 00:08:44.120
That's more of a loading pattern.

191
00:08:44.120 --> 00:08:49.000
What we see here is the when we now look at the wedge swing we can see that the

192
00:08:49.000 --> 00:08:49.520
red and

193
00:08:49.520 --> 00:08:52.850
green kind of change direction together and the red is underneath the other

194
00:08:52.850 --> 00:08:53.400
graphs for

195
00:08:53.400 --> 00:08:54.560
the entire downswing.

196
00:08:54.560 --> 00:08:59.320
We can see that the blue and the brown are pretty much mirrored on top of each

197
00:08:59.320 --> 00:08:59.840
other.

198
00:08:59.840 --> 00:09:04.850
If I kind of toggle back and forth you can see the general shift of being less

199
00:09:04.850 --> 00:09:05.440
of a load

200
00:09:05.440 --> 00:09:08.640
and more of a cast when we get to the wedge.

201
00:09:08.640 --> 00:09:13.330
So here's another golfer and in this one we'll see primarily a lower body or a

202
00:09:13.330 --> 00:09:13.960
hip change

203
00:09:13.960 --> 00:09:18.970
so we can see the red line being well above the green line and kind of going

204
00:09:18.970 --> 00:09:19.640
first and

205
00:09:19.640 --> 00:09:25.720
faster and then if we shift we can see that the red line is now kind of in with

206
00:09:25.720 --> 00:09:25.920
going

207
00:09:25.920 --> 00:09:32.940
at about the same speed as the other parts of the body kind of like so.

208
00:09:32.940 --> 00:09:37.000
Here's another example of a golfer who makes adjustments to both the hips and

209
00:09:37.000 --> 00:09:37.560
trunks.

210
00:09:37.560 --> 00:09:42.920
You can look at that transition starting sequence and we can see pretty clearly

211
00:09:42.920 --> 00:09:43.720
that that red

212
00:09:43.720 --> 00:09:48.820
line goes from leading the early part of the downswing to now just kind of

213
00:09:48.820 --> 00:09:49.760
supporting

214
00:09:49.760 --> 00:09:55.840
and we can see that the torso kind of follows in that same casting pattern as

215
00:09:55.840 --> 00:09:56.600
well.

216
00:09:56.600 --> 00:10:02.750
Okay so we see that the tour pros tend to use a similar pattern throughout the

217
00:10:02.750 --> 00:10:03.640
bag but

218
00:10:03.640 --> 00:10:05.000
it's more of a cast.

219
00:10:05.000 --> 00:10:07.520
What about amateurs?

220
00:10:07.520 --> 00:10:12.210
Now amateurs are typically going to struggle with one end or the other and more

221
00:10:12.210 --> 00:10:12.720
often than

222
00:10:12.720 --> 00:10:14.480
not they struggle with the driver.

223
00:10:14.480 --> 00:10:20.590
So here's a mid handicap golfer with their driver and we can see that it's

224
00:10:20.590 --> 00:10:21.440
already a

225
00:10:21.440 --> 00:10:22.440
cast pattern.

226
00:10:22.440 --> 00:10:27.720
We can see that it's going to be difficult to be or even if it becomes more of

227
00:10:27.720 --> 00:10:28.280
a cast

228
00:10:28.280 --> 00:10:32.800
pattern it's never a loading pattern which is part of what's required to have

229
00:10:32.800 --> 00:10:33.520
the proper

230
00:10:33.520 --> 00:10:36.000
angle of attack and hit a driver well.

231
00:10:36.000 --> 00:10:40.290
So we can see that yes the lower body does get a little bit slower but you can

232
00:10:40.290 --> 00:10:40.840
see for

233
00:10:40.840 --> 00:10:47.080
all intended purposes most of the swing doesn't really change.

234
00:10:47.080 --> 00:10:51.780
In fact if we compare this as his driver this is his wedge we can see that the

235
00:10:51.780 --> 00:10:52.620
lower body

236
00:10:52.620 --> 00:10:57.310
actually has better sequencing and starts earlier with the wedge than it did

237
00:10:57.310 --> 00:10:57.880
with the

238
00:10:57.880 --> 00:10:59.600
driver.

239
00:10:59.600 --> 00:11:05.650
So again this is an example of a golfer failing to make the changes between a

240
00:11:05.650 --> 00:11:06.320
driver

241
00:11:06.320 --> 00:11:09.610
and a wedge swing so this golfer is much better with hitting the short irons

242
00:11:09.610 --> 00:11:10.320
than he is with

243
00:11:10.320 --> 00:11:12.600
hitting the driver.

244
00:11:12.600 --> 00:11:17.960
Here's another golfer who has a pretty clear cast pattern and we can see the

245
00:11:17.960 --> 00:11:19.040
shift between

246
00:11:19.040 --> 00:11:23.040
these two you can see that the overall pattern looks about the same.

247
00:11:23.040 --> 00:11:26.550
The scale is just a little different so the graph is kind of jumping around but

248
00:11:26.550 --> 00:11:27.000
you can

249
00:11:27.000 --> 00:11:32.800
see that the pattern between the two is pretty close to the same.

250
00:11:32.800 --> 00:11:40.050
One last example we've got driver here and wedge here you can see that if

251
00:11:40.050 --> 00:11:41.240
anything this

252
00:11:41.240 --> 00:11:49.430
golfer actually struggles with having more of a load pattern with the wrist

253
00:11:49.430 --> 00:11:50.880
with the wedge

254
00:11:50.880 --> 00:11:52.560
here than he does with the driver.

255
00:11:52.560 --> 00:11:57.920
So he has more of a cast pattern with the driver than he does with the wedge.

256
00:11:57.920 --> 00:12:00.960
The wedge he actually demonstrates more of the downswing loading pattern.

257
00:12:00.960 --> 00:12:05.650
So this 10 handicap tends to struggle a little bit more with wedge consistency

258
00:12:05.650 --> 00:12:06.560
contact.

259
00:12:06.560 --> 00:12:11.250
Okay so we saw that pros made these adjustments to their patterns where am

260
00:12:11.250 --> 00:12:12.120
ateurs typically

261
00:12:12.120 --> 00:12:17.810
kept the same pattern or in one case actually reversed the pattern in the wrong

262
00:12:17.810 --> 00:12:18.800
direction.

263
00:12:18.800 --> 00:12:24.010
So looking back at our hypotheses we can rule out that the swings are identical

264
00:12:24.010 --> 00:12:24.640
or at least

265
00:12:24.640 --> 00:12:28.260
I'm willing to rule out that the swings are identical and that it's a just ball

266
00:12:28.260 --> 00:12:28.840
position.

267
00:12:28.840 --> 00:12:33.530
I think we've built some support for the case that it's a total body versus an

268
00:12:33.530 --> 00:12:34.200
upper body

269
00:12:34.200 --> 00:12:38.960
move and I think we've built some case for the speed versus precision argument

270
00:12:38.960 --> 00:12:39.400
but we

271
00:12:39.400 --> 00:12:44.890
haven't done much to address some of the other goals like the angle of attack

272
00:12:44.890 --> 00:12:45.400
or the

273
00:12:45.400 --> 00:12:47.560
axis tilt or sweep versus strike.

274
00:12:47.560 --> 00:12:52.720
So that's what we'll look at next when we talk more about these positions.

275
00:12:52.720 --> 00:12:57.240
Now this image up here is the same golfer hitting a full swing with a sand

276
00:12:57.240 --> 00:12:57.840
wedge on

277
00:12:57.840 --> 00:13:00.320
the right and a driver on the left.

278
00:13:00.320 --> 00:13:03.680
Now we can see that there are some different looks to these movements.

279
00:13:03.680 --> 00:13:07.640
We can see that the upper body is a little bit more on top of the lower body

280
00:13:07.640 --> 00:13:08.280
there's

281
00:13:08.280 --> 00:13:13.640
differences in the extension or the width between the upper body and the hands

282
00:13:13.640 --> 00:13:14.040
and we

283
00:13:14.040 --> 00:13:17.200
can see that there's differences in the arm straightening.

284
00:13:17.200 --> 00:13:20.540
Now again I'm not here to tell you that these need to be intentional

285
00:13:20.540 --> 00:13:21.720
differences but I am

286
00:13:21.720 --> 00:13:25.880
going to show you the data that shows that you do need to make some adjustments

287
00:13:25.880 --> 00:13:26.280
if you're

288
00:13:26.280 --> 00:13:31.080
going to have success with both clubs.

289
00:13:31.080 --> 00:13:34.680
What I found looking at the general trends is that there is a big difference in

290
00:13:34.680 --> 00:13:35.560
the sway

291
00:13:35.560 --> 00:13:36.560
pattern.

292
00:13:36.560 --> 00:13:39.470
So the sway is the movement of the upper body or the lower body either towards

293
00:13:39.470 --> 00:13:39.960
the target

294
00:13:39.960 --> 00:13:41.560
or away from the target.

295
00:13:41.560 --> 00:13:45.550
So it's not just a bad thing like a sway in the backswing it's just the term we

296
00:13:45.550 --> 00:13:45.840
use

297
00:13:45.840 --> 00:13:51.040
for the linear movement of the body in that plane.

298
00:13:51.040 --> 00:13:56.290
The general pattern was that the irons were more stacked and the driver had

299
00:13:56.290 --> 00:13:57.320
more of a tilt

300
00:13:57.320 --> 00:13:59.400
away from the target.

301
00:13:59.400 --> 00:14:05.240
Most golfers adjusted the thorax while keeping the lower body the same but

302
00:14:05.240 --> 00:14:06.440
about or a small

303
00:14:06.440 --> 00:14:11.130
percentage adjusted the pelvis while keeping the upper body the same and a

304
00:14:11.130 --> 00:14:12.320
handful of them

305
00:14:12.320 --> 00:14:13.880
changed both.

306
00:14:13.880 --> 00:14:17.570
But it was about two thirds of the golfers who kept the lower body or the pel

307
00:14:17.570 --> 00:14:18.240
vis pretty

308
00:14:18.240 --> 00:14:22.160
consistent and made mostly adjustment with the thorax.

309
00:14:22.160 --> 00:14:27.280
There was a difference in both the lift and the thrust pattern but they aren't

310
00:14:27.280 --> 00:14:28.080
as significant

311
00:14:28.080 --> 00:14:31.480
so we're not going to look at them in this video.

312
00:14:31.480 --> 00:14:35.840
So this golfer is that typical pattern that adjusts the thorax.

313
00:14:35.840 --> 00:14:40.960
This graph is now looking at the pelvis, sway is thrust and lifts.

314
00:14:40.960 --> 00:14:45.000
The pelvis sway is the main graph we're going to look at which is the red line.

315
00:14:45.000 --> 00:14:50.840
So the red line is looking at the linear movement of the pelvis towards or away

316
00:14:50.840 --> 00:14:51.280
from

317
00:14:51.280 --> 00:14:52.640
the target.

318
00:14:52.640 --> 00:14:55.560
When it goes negative it's swaying off the ball or it's moving away from the

319
00:14:55.560 --> 00:14:56.000
target

320
00:14:56.000 --> 00:15:00.720
when it goes positive it is swaying towards the target.

321
00:15:00.720 --> 00:15:04.760
So this golfer had a little bit of a weight shift during takeaway and then more

322
00:15:04.760 --> 00:15:05.600
of a centered

323
00:15:05.600 --> 00:15:11.270
pivot and then shifted towards the target and the downswing and slid on the way

324
00:15:11.270 --> 00:15:12.240
through.

325
00:15:12.240 --> 00:15:15.550
If you look down at the bottom of the screen, bottom left you can see the

326
00:15:15.550 --> 00:15:16.320
amount of sway

327
00:15:16.320 --> 00:15:17.320
at impact.

328
00:15:17.320 --> 00:15:21.500
So I have all these graphs kind of frozen at that point in time.

329
00:15:21.500 --> 00:15:27.420
So between setup and impact the golfer shifted 5.4 inches closer to the target

330
00:15:27.420 --> 00:15:30.080
for the driver.

331
00:15:30.080 --> 00:15:35.120
Now with an eight iron the golfer shifted 5.1 inches so it was a little bit

332
00:15:35.120 --> 00:15:35.720
less but

333
00:15:35.720 --> 00:15:40.770
pretty close and if I toggle back and forth you can see the overall pattern for

334
00:15:40.770 --> 00:15:41.320
the red

335
00:15:41.320 --> 00:15:45.480
is pretty consistent, pretty similar between these two.

336
00:15:45.480 --> 00:15:49.790
Now if we look at the upper body it's the same graph so we're looking at the

337
00:15:49.790 --> 00:15:50.400
red line

338
00:15:50.400 --> 00:15:55.410
which is the thorax sway and we'll see a little bit of a shift off the ball

339
00:15:55.410 --> 00:15:57.080
during the takeaway

340
00:15:57.080 --> 00:16:02.220
and then a little bit of a shift towards the target during the early part of

341
00:16:02.220 --> 00:16:03.320
the downswing

342
00:16:03.320 --> 00:16:05.970
and then once they've done that little shift towards the target you'll see with

343
00:16:05.970 --> 00:16:06.440
the driver

344
00:16:06.440 --> 00:16:10.680
there's a pretty significant movement away from the target.

345
00:16:10.680 --> 00:16:14.640
I refer to that movement as part of the bracing strategy or how they use their

346
00:16:14.640 --> 00:16:15.400
body to help

347
00:16:15.400 --> 00:16:20.680
stabilize and get in the position to deliver the arms in the right way.

348
00:16:20.680 --> 00:16:25.540
So this golfer shifted about two and a half inches towards the target and then

349
00:16:25.540 --> 00:16:26.000
by the

350
00:16:26.000 --> 00:16:29.930
end of their release so roughly when the club's about parallel they're about 1.

351
00:16:29.930 --> 00:16:30.760
5 inches away

352
00:16:30.760 --> 00:16:34.840
from wherever they started but you can see that between those two there's a

353
00:16:34.840 --> 00:16:35.960
pretty consistent

354
00:16:35.960 --> 00:16:39.840
movement away from the target.

355
00:16:39.840 --> 00:16:44.110
Now here we have that same golfer with an iron and we saw that the pelvis was

356
00:16:44.110 --> 00:16:44.640
about the

357
00:16:44.640 --> 00:16:49.490
same we can see that the pattern, the shape of the red line between these two

358
00:16:49.490 --> 00:16:50.440
looks pretty

359
00:16:50.440 --> 00:16:54.790
similar but we can see that some of the magnitudes are different so this golfer

360
00:16:54.790 --> 00:16:55.640
had about the

361
00:16:55.640 --> 00:17:02.050
same shift towards the target during transition that movement helps create the

362
00:17:02.050 --> 00:17:03.080
pressure in

363
00:17:03.080 --> 00:17:07.770
the lead foot and then during the release we can see that this golfer didn't

364
00:17:07.770 --> 00:17:08.680
shift nearly

365
00:17:08.680 --> 00:17:13.900
as much off the ball in fact or sorry away from the target not off the ball so

366
00:17:13.900 --> 00:17:14.840
this golfer

367
00:17:14.840 --> 00:17:20.250
shifted towards the target and then when they made contact they're about 1.6

368
00:17:20.250 --> 00:17:21.840
inches closer

369
00:17:21.840 --> 00:17:27.250
to the target than where they started so because we're comparing where they

370
00:17:27.250 --> 00:17:28.320
started if a golfer

371
00:17:28.320 --> 00:17:32.630
sets up with more tilt and gets more behind the ball with a driver and then

372
00:17:32.630 --> 00:17:33.400
sets up more

373
00:17:33.400 --> 00:17:37.280
stacked with an iron we're going to tend to see even with that the upper body

374
00:17:37.280 --> 00:17:37.840
is going

375
00:17:37.840 --> 00:17:42.670
to get more in front of where they started with the iron where with the driver

376
00:17:42.670 --> 00:17:43.280
they're

377
00:17:43.280 --> 00:17:47.610
going to work their way more behind where they started so even though they're

378
00:17:47.610 --> 00:17:48.240
starting

379
00:17:48.240 --> 00:17:52.370
further away they still work more behind with the driver but this golfer if we

380
00:17:52.370 --> 00:17:52.960
toggle back

381
00:17:52.960 --> 00:17:57.650
and forth we can see the differences even though the pattern looks similar we

382
00:17:57.650 --> 00:17:58.040
can see

383
00:17:58.040 --> 00:18:03.400
that this golfer is not shifting their upper body nearly as far off or away

384
00:18:03.400 --> 00:18:04.600
from the target

385
00:18:04.600 --> 00:18:08.810
during the release and that creates the difference in the axis tilt so this gol

386
00:18:08.810 --> 00:18:09.680
fer had the pelvis

387
00:18:09.680 --> 00:18:14.690
move about the same amount but the there was a little over a 1 inch difference

388
00:18:14.690 --> 00:18:15.240
in where

389
00:18:15.240 --> 00:18:20.240
the position of the upper body was and that helped create the axis tilt

390
00:18:20.240 --> 00:18:21.360
different for

391
00:18:21.360 --> 00:18:29.330
the driver compared to the short iron now here's a second golfer looking at

392
00:18:29.330 --> 00:18:30.760
another one of

393
00:18:30.760 --> 00:18:34.960
the classic patterns of more of the thorax adjusters so this golfer actually

394
00:18:34.960 --> 00:18:35.500
shifted

395
00:18:35.500 --> 00:18:40.630
their lower body 3.7 inches with both the driver and the iron driver and nine

396
00:18:40.630 --> 00:18:41.120
iron you

397
00:18:41.120 --> 00:18:45.450
can see very little difference in the pattern of the red line there's a little

398
00:18:45.450 --> 00:18:46.280
difference

399
00:18:46.280 --> 00:18:50.970
in the pattern of the blue line and green line but we're primarily looking at

400
00:18:50.970 --> 00:18:51.480
the red

401
00:18:51.480 --> 00:18:58.330
line for this section so now we can go back and forth between the driver and

402
00:18:58.330 --> 00:18:59.200
the iron and

403
00:18:59.200 --> 00:19:05.450
we can see again that similar shift so while they shifted about the same amount

404
00:19:05.450 --> 00:19:05.660
towards

405
00:19:05.660 --> 00:19:12.320
the target to help apply the pressure into the lead foot we can see during the

406
00:19:12.320 --> 00:19:13.120
release

407
00:19:13.120 --> 00:19:17.340
with the driver this golfer works about two and a half inches or a total of

408
00:19:17.340 --> 00:19:18.080
about four

409
00:19:18.080 --> 00:19:23.220
or five inches away from the target from the maximum point there to the maximum

410
00:19:23.220 --> 00:19:24.640
point there

411
00:19:24.640 --> 00:19:30.120
and at impact is about half an inch further away than where he started with the

412
00:19:30.120 --> 00:19:30.720
driver

413
00:19:30.720 --> 00:19:35.410
and then with an iron we can see that he goes from about a little less than two

414
00:19:35.410 --> 00:19:35.600
and

415
00:19:35.600 --> 00:19:40.700
a half to right around zero so he has about half the amount of shift away from

416
00:19:40.700 --> 00:19:41.560
the target

417
00:19:41.560 --> 00:19:45.480
even though the pelvis was in exactly the same position so you can see the

418
00:19:45.480 --> 00:19:46.120
general slope

419
00:19:46.120 --> 00:19:53.030
change as well as the magnitude change here's one more thorax adjuster because

420
00:19:53.030 --> 00:19:53.640
it's the

421
00:19:53.640 --> 00:19:58.350
more dominant pattern I wanted to show a few examples so this golfer shifted

422
00:19:58.350 --> 00:19:59.240
seven point

423
00:19:59.240 --> 00:20:06.440
one inches towards the target with the driver seven inches with the eight iron

424
00:20:06.440 --> 00:20:07.400
and again

425
00:20:07.400 --> 00:20:12.090
you can see a pretty consistent pattern or similar looking graphs between these

426
00:20:12.090 --> 00:20:12.480
two that's

427
00:20:12.480 --> 00:20:18.730
clearly the same golfer now if we look at the adjustment of the upper body we

428
00:20:18.730 --> 00:20:19.440
can see

429
00:20:19.440 --> 00:20:23.640
that there's a pretty big difference between the upper body now this golfer

430
00:20:23.640 --> 00:20:24.400
doesn't get

431
00:20:24.400 --> 00:20:28.810
quite as far away from the golf ball so this golfer is probably gonna or sorry

432
00:20:28.810 --> 00:20:29.440
away from

433
00:20:29.440 --> 00:20:34.130
the target this golfer is probably going to have more of a downward angle of

434
00:20:34.130 --> 00:20:34.960
attack because

435
00:20:34.960 --> 00:20:39.650
his upper body is still two point one inches closer than where it started he

436
00:20:39.650 --> 00:20:40.280
doesn't really

437
00:20:40.280 --> 00:20:48.130
have a a big shift away from the target but with the iron you can see that it's

438
00:20:48.130 --> 00:20:48.480
less so

439
00:20:48.480 --> 00:20:53.610
you can see that this is a more of a gradual slope it's not quite as sharp and

440
00:20:53.610 --> 00:20:54.200
you can

441
00:20:54.200 --> 00:20:59.580
see that he finishes two and a half inches closer you know his lowest peak is

442
00:20:59.580 --> 00:21:00.160
two and

443
00:21:00.160 --> 00:21:04.070
a half inches closer than where he started so that upper body is definitely

444
00:21:04.070 --> 00:21:04.680
shifting

445
00:21:04.680 --> 00:21:10.630
more towards the target with the iron than he was with the driver while the

446
00:21:10.630 --> 00:21:11.440
blue and

447
00:21:11.440 --> 00:21:18.960
the green stay somewhat consistent now there was a small subset of golfers who

448
00:21:18.960 --> 00:21:19.400
tended to

449
00:21:19.400 --> 00:21:24.630
adjust the pelvis instead of the upper body so that looks more like this with

450
00:21:24.630 --> 00:21:25.480
the driver

451
00:21:25.480 --> 00:21:30.840
this golfer if I just showed you these two without us looking at the scale you

452
00:21:30.840 --> 00:21:31.320
would

453
00:21:31.320 --> 00:21:36.330
say that that's pretty close to the same pattern but if we look at the values

454
00:21:36.330 --> 00:21:36.760
we can

455
00:21:36.760 --> 00:21:41.560
see that in the bottom left hand corner with the driver he's shifted nine

456
00:21:41.560 --> 00:21:42.680
inches towards

457
00:21:42.680 --> 00:21:47.540
the target with the pitching wedge he's only shifted 6.3 inches towards the

458
00:21:47.540 --> 00:21:48.320
target so about

459
00:21:48.320 --> 00:21:54.920
a three inch difference between where his lower body was compared to the start

460
00:21:54.920 --> 00:21:55.800
position

461
00:21:55.800 --> 00:22:00.490
so now what we'll see by looking at his upper body is we can see that the upper

462
00:22:00.490 --> 00:22:01.240
body graphs

463
00:22:01.240 --> 00:22:06.480
tend to have a more consistent pattern so he only had a shift of a difference

464
00:22:06.480 --> 00:22:07.120
of about

465
00:22:07.120 --> 00:22:11.360
point eight inches so the difference between his lower body and his upper body

466
00:22:11.360 --> 00:22:12.880
still increased

467
00:22:12.880 --> 00:22:19.390
about two inches based on the difference between the driver and the iron but he

468
00:22:19.390 --> 00:22:20.080
did it more

469
00:22:20.080 --> 00:22:24.770
by increasing the lower body not by moving the upper body back and that two

470
00:22:24.770 --> 00:22:25.480
inch the the

471
00:22:25.480 --> 00:22:33.380
average in the database was about 2.1 inches of additional shift so now here's

472
00:22:33.380 --> 00:22:35.380
the smallest

473
00:22:35.380 --> 00:22:41.990
subset was more of the adjuster of both so neither of them is going to stay the

474
00:22:41.990 --> 00:22:42.520
same

475
00:22:42.520 --> 00:22:47.040
they're going to change kind of different amounts in order to create that two

476
00:22:47.040 --> 00:22:47.760
inch difference

477
00:22:47.760 --> 00:22:51.270
between the upper body or the two inch greater difference between the upper

478
00:22:51.270 --> 00:22:51.920
body and the

479
00:22:51.920 --> 00:22:58.400
lower body for their own pattern so here we've got golfer going six point four

480
00:22:58.400 --> 00:22:59.000
inches with

481
00:22:59.000 --> 00:23:04.240
the driver and then five point eight inches with the iron and then with the

482
00:23:04.240 --> 00:23:05.080
upper body

483
00:23:05.080 --> 00:23:11.580
we can see a similar looking pattern but his upper body moves about point six

484
00:23:11.580 --> 00:23:12.720
inches closer

485
00:23:12.720 --> 00:23:16.780
to the target with the iron than it did with the driver so he had a little bit

486
00:23:16.780 --> 00:23:17.360
of shift

487
00:23:17.360 --> 00:23:20.710
from lower body and a little bit of shift from the upper body and that combo

488
00:23:20.710 --> 00:23:21.320
gives him the

489
00:23:21.320 --> 00:23:29.420
axis tilt that he's looking for in general there's a pretty big difference in

490
00:23:29.420 --> 00:23:30.120
the pattern

491
00:23:30.120 --> 00:23:34.830
when we compare the two ends of the spectrum when we looking at this axis still

492
00:23:34.830 --> 00:23:35.440
or we're

493
00:23:35.440 --> 00:23:40.900
looking at this way those irons there tend to be more stacked so you know just

494
00:23:40.900 --> 00:23:41.760
a couple

495
00:23:41.760 --> 00:23:45.140
inch difference whether it's two to four or something like that difference

496
00:23:45.140 --> 00:23:45.800
between the

497
00:23:45.800 --> 00:23:49.640
upper body and the lower body but with the driver you'll see a much greater

498
00:23:49.640 --> 00:23:50.360
difference

499
00:23:50.360 --> 00:23:55.050
especially if you look at the maximum difference such as at the end of their

500
00:23:55.050 --> 00:23:55.920
release it can

501
00:23:55.920 --> 00:24:00.440
be somewhere in the you know five six even up to eight inch difference between

502
00:24:00.440 --> 00:24:01.080
the upper

503
00:24:01.080 --> 00:24:05.260
body and the lower body so if your upper body is directly on top of your lower

504
00:24:05.260 --> 00:24:05.680
body you're

505
00:24:05.680 --> 00:24:13.350
probably going to struggle with the driver so what about amateurs if we look at

506
00:24:13.350 --> 00:24:13.880
them we're

507
00:24:13.880 --> 00:24:17.200
going to tend to see a little bit of change right similar to what we saw with

508
00:24:17.200 --> 00:24:18.000
the kinematics

509
00:24:18.000 --> 00:24:25.310
sequence so here's a amateur golfer who's wedge swing so the the driver swing

510
00:24:25.310 --> 00:24:25.960
he had

511
00:24:25.960 --> 00:24:32.450
an extra inch of shift towards the target so it went 4.8 to 3.8 but we can see

512
00:24:32.450 --> 00:24:33.160
overall

513
00:24:33.160 --> 00:24:38.570
the patterns kind of about the same so that'd be fine it we're expecting to see

514
00:24:38.570 --> 00:24:39.240
a little

515
00:24:39.240 --> 00:24:45.070
bit more shift away from the target with the um with the iron then we do with

516
00:24:45.070 --> 00:24:45.920
the driver

517
00:24:45.920 --> 00:24:51.410
and we can see that there's a little bit of a shift but again these two are

518
00:24:51.410 --> 00:24:52.240
also very

519
00:24:52.240 --> 00:24:56.120
close four inch shift um with the driver so we were expecting to see that

520
00:24:56.120 --> 00:24:57.480
actually be

521
00:24:57.480 --> 00:25:01.820
less than the wedge he shifted more than the wedge so the actual difference

522
00:25:01.820 --> 00:25:02.440
between the

523
00:25:02.440 --> 00:25:06.040
axis tilt stayed about the same because he he gained some with the pelvis but

524
00:25:06.040 --> 00:25:06.400
then he

525
00:25:06.400 --> 00:25:12.220
lost some based on the pelvis and thorax so both shifted but the difference was

526
00:25:12.220 --> 00:25:12.560
pretty

527
00:25:12.560 --> 00:25:19.690
much the same on that case now we've got uh another golfer who we can see has a

528
00:25:19.690 --> 00:25:20.560
about

529
00:25:20.560 --> 00:25:26.050
a one inch difference between where the pelvis is and then if we jump to the

530
00:25:26.050 --> 00:25:27.040
lower body this

531
00:25:27.040 --> 00:25:32.400
is the driver and then this is the wedge we can see a 1.5 inch difference but

532
00:25:32.400 --> 00:25:33.200
the driver

533
00:25:33.200 --> 00:25:39.640
is actually more ahead or closer to the target than the wedge so he negates um

534
00:25:39.640 --> 00:25:40.880
what he gains

535
00:25:40.880 --> 00:25:44.720
with the pelvis again it ends up being about the same relationship and that's a

536
00:25:44.720 --> 00:25:45.600
very consistent

537
00:25:45.600 --> 00:25:49.420
pattern that you'll see with kind of the mid handicap level where whatever that

538
00:25:49.420 --> 00:25:49.920
axis tilt

539
00:25:49.920 --> 00:25:55.520
relationship is with one swing they'll typically have that with all of their

540
00:25:55.520 --> 00:25:58.000
full swings so amateurs

541
00:25:58.000 --> 00:26:02.060
frequently retain those similar axis tilt relationships and that typically

542
00:26:02.060 --> 00:26:03.120
causes a problem

543
00:26:03.120 --> 00:26:09.200
at one end of the spectrum or the other back to our hypotheses we know that

544
00:26:09.200 --> 00:26:10.120
there's some

545
00:26:10.120 --> 00:26:13.960
differences but we're starting to confirm what a lot of the coaches thought the

546
00:26:13.960 --> 00:26:14.600
one piece that

547
00:26:14.600 --> 00:26:17.560
I couldn't really confirm was standing further away from the golf ball and that

548
00:26:17.560 --> 00:26:18.040
's just not

549
00:26:18.040 --> 00:26:23.050
measured on the 3d system but the good news is pros were or coaches were kind

550
00:26:23.050 --> 00:26:24.120
of looking in the

551
00:26:24.120 --> 00:26:31.680
right areas and the the data is supporting the difference in the patterns of

552
00:26:31.680 --> 00:26:33.080
the load versus the

553
00:26:33.080 --> 00:26:37.770
cast and the more axis tilt versus less axis tilt so amateurs really just need

554
00:26:37.770 --> 00:26:39.400
to learn to adjust

555
00:26:39.400 --> 00:26:42.520
a few key parameters in order to have success throughout the bag

556
00:26:42.520 --> 00:26:48.600
now let's look at one thing that was not mentioned by the coaches but that I

557
00:26:48.600 --> 00:26:49.480
think is

558
00:26:49.480 --> 00:26:54.690
incredibly useful which is looking at the amount of supination because the what

559
00:26:54.690 --> 00:26:55.640
the body does

560
00:26:55.640 --> 00:27:00.850
and what happens in the load pattern is typically going to affect what happens

561
00:27:00.850 --> 00:27:01.720
in the release and

562
00:27:01.720 --> 00:27:07.100
vice versa so what we're going to look at is just one simple parameter we're

563
00:27:07.100 --> 00:27:08.120
going to look at the

564
00:27:08.120 --> 00:27:13.930
blue line the blue line is looking at pronation supination when it is negative

565
00:27:13.930 --> 00:27:14.840
it's pronating

566
00:27:14.840 --> 00:27:20.360
and when it's positive it is supinating so what we'll see here is the golfer

567
00:27:20.360 --> 00:27:21.480
with the left wrist

568
00:27:21.480 --> 00:27:26.970
is going to have some pronation and reach a maximum value somewhere in mid down

569
00:27:26.970 --> 00:27:27.960
swing and then

570
00:27:27.960 --> 00:27:34.280
supinate during the entire release now what's interesting is you'll see a

571
00:27:34.280 --> 00:27:36.200
similar pattern

572
00:27:36.200 --> 00:27:43.720
but the supination value will tend to be increased on the driver swing so he's

573
00:27:43.720 --> 00:27:45.080
going to get into a

574
00:27:45.080 --> 00:27:49.770
more of a supinated position by the end of the release when he gets up here

575
00:27:49.770 --> 00:27:51.480
compared to what he

576
00:27:51.480 --> 00:27:57.840
does with the wedge so here's another example and we can look at the actual

577
00:27:57.840 --> 00:27:59.960
numbers so somewhere down

578
00:27:59.960 --> 00:28:06.720
here you know whether that's 60 just below 56 we can see he gets close to 70

579
00:28:06.720 --> 00:28:08.200
degrees of supination

580
00:28:08.200 --> 00:28:14.960
by the end of the release now if we look at the wedge swing we'll see a little

581
00:28:14.960 --> 00:28:16.440
bit less we're

582
00:28:16.440 --> 00:28:20.760
pretty close to the same amount of pronation during the downswing but we'll see

583
00:28:20.760 --> 00:28:22.520
significantly

584
00:28:22.520 --> 00:28:28.600
less supination on the way through one of the interesting ones that i saw

585
00:28:28.600 --> 00:28:30.680
looking at the amateurs

586
00:28:30.680 --> 00:28:35.370
was this golfer who actually had more supination with his wedge swing than he

587
00:28:35.370 --> 00:28:36.920
does with the driver

588
00:28:36.920 --> 00:28:41.610
swing this is also the golfer who tended to have more of a cast pattern with

589
00:28:41.610 --> 00:28:42.920
the driver than he had

590
00:28:42.920 --> 00:28:49.090
with the with the wedge so what you'll see is the more that you load those

591
00:28:49.090 --> 00:28:50.680
wrists by using good

592
00:28:50.680 --> 00:28:57.320
sequencing good proximal to distal loading patterns you'll tend to see more of

593
00:28:57.320 --> 00:28:58.840
this supination value

594
00:28:58.840 --> 00:29:05.660
increase with the release so this golfer gets close to 80 degrees supination on

595
00:29:05.660 --> 00:29:06.760
the way through

596
00:29:06.760 --> 00:29:13.640
with a driver close to 60 degrees and what you'll this relates to a lot of the

597
00:29:13.640 --> 00:29:15.400
arm tension that amateurs

598
00:29:15.400 --> 00:29:20.200
describe when they feel like they're bracing or they're squeezing their forms

599
00:29:20.200 --> 00:29:20.680
to help

600
00:29:20.680 --> 00:29:24.050
control the clubface on the way through or to start bending their arms like

601
00:29:24.050 --> 00:29:24.760
they're getting

602
00:29:24.760 --> 00:29:29.450
into a chicken wing pattern those will tend to diminish the amount of sup

603
00:29:29.450 --> 00:29:30.920
ination on the way through

604
00:29:30.920 --> 00:29:39.800
so that was just a quick little point that i think gets overlooked when talking

605
00:29:39.800 --> 00:29:40.120
about the

606
00:29:40.120 --> 00:29:43.250
differences between the iron and the driver but there are definitely some

607
00:29:43.250 --> 00:29:44.840
differences between

608
00:29:44.840 --> 00:29:50.620
the amount of supination in the driver and the iron swing if it's going to look

609
00:29:50.620 --> 00:29:51.960
the same on video

610
00:29:51.960 --> 00:29:58.080
i'll show you what i mean so we're going to get into some case studies we're

611
00:29:58.080 --> 00:29:59.480
going to look at some

612
00:29:59.480 --> 00:30:05.160
2d examples so that you'll be able to relate what you're seeing on these graphs

613
00:30:05.160 --> 00:30:06.360
to what actually

614
00:30:06.360 --> 00:30:13.960
happens with 2d video which the way most of us are used to looking at it so the

615
00:30:13.960 --> 00:30:15.000
coaching keys

616
00:30:15.000 --> 00:30:19.080
would be looking at the access tilt the power source the release style and

617
00:30:19.080 --> 00:30:20.600
something that i

618
00:30:20.600 --> 00:30:24.060
don't have data for but has worked very well for me which is looking at club

619
00:30:24.060 --> 00:30:24.920
height to ground

620
00:30:24.920 --> 00:30:30.390
now in this presentation we're going to look at a couple of different key

621
00:30:30.390 --> 00:30:31.080
concepts so

622
00:30:31.720 --> 00:30:36.540
the follow away from the target or the access tilt movement when we look at the

623
00:30:36.540 --> 00:30:37.000
driver's

624
00:30:37.000 --> 00:30:40.950
case study and with the iron we're going to look at a little bit of low point

625
00:30:40.950 --> 00:30:41.560
training

626
00:30:41.560 --> 00:30:50.040
so here is a single lesson a before and after this is looking at a case study

627
00:30:50.040 --> 00:30:50.760
looking at

628
00:30:50.760 --> 00:30:57.520
the amount of tilt so this golfer we had been working together for a few

629
00:30:57.520 --> 00:30:58.120
lessons already

630
00:30:58.120 --> 00:31:03.900
mostly working on the release and i'll show you what we did during this lesson

631
00:31:03.900 --> 00:31:04.680
to get the changes

632
00:31:04.680 --> 00:31:09.200
to go from this over here on the left this amount of extension to this over

633
00:31:09.200 --> 00:31:10.360
here on the right

634
00:31:10.360 --> 00:31:19.800
so here's the initial swing this was one of his swings during warm-up and you

635
00:31:19.800 --> 00:31:20.600
can see those arms

636
00:31:20.600 --> 00:31:27.560
bending on the way through now here he is during warm-up with an iron and he he

637
00:31:27.560 --> 00:31:28.760
described having

638
00:31:28.760 --> 00:31:32.830
some good success with his iron consistency and most of the pros who i showed

639
00:31:32.830 --> 00:31:33.800
this to at the

640
00:31:33.800 --> 00:31:38.070
world ball fitness summit agreed that this looks better he's got more arm

641
00:31:38.070 --> 00:31:39.240
extension you know there's

642
00:31:39.240 --> 00:31:43.340
still a little bit of maybe a scoopish pattern but he's got much better arm

643
00:31:43.340 --> 00:31:44.520
extension on the way

644
00:31:44.520 --> 00:31:48.220
through it looks like he's doing something different with the driver than the

645
00:31:48.220 --> 00:31:50.040
iron but now from looking

646
00:31:50.040 --> 00:31:54.260
at the data perhaps you'll understand that he's actually doing closer to the

647
00:31:54.260 --> 00:31:54.840
same thing

648
00:31:54.840 --> 00:32:00.670
with the driver and the iron and that's why it looks different so i wanted him

649
00:32:00.670 --> 00:32:01.480
to understand

650
00:32:01.480 --> 00:32:06.840
the difference in the relationship of the axis tilt so i gave him a drill that

651
00:32:06.840 --> 00:32:07.320
we have on the

652
00:32:07.320 --> 00:32:13.140
site to help him feel pushing into that front leg while those arms extend past

653
00:32:13.140 --> 00:32:15.240
his body and making

654
00:32:15.240 --> 00:32:20.040
sure that his upper body fell away from the target a little bit helping to

655
00:32:20.040 --> 00:32:20.840
create that

656
00:32:20.840 --> 00:32:25.590
improved axis tilt so we discussed it and he did this drill took about three

657
00:32:25.590 --> 00:32:26.680
minutes in between

658
00:32:26.680 --> 00:32:32.040
that first swing and what you're going to see right here so this was the very

659
00:32:32.040 --> 00:32:32.920
next swing after

660
00:32:32.920 --> 00:32:37.720
doing his drill and understanding the concept better and he was able to

661
00:32:37.720 --> 00:32:39.720
increase his launch angle

662
00:32:39.720 --> 00:32:44.440
and pick up about 30 yards but the big thing was he was able to control his

663
00:32:44.440 --> 00:32:46.840
trajectory in the

664
00:32:46.840 --> 00:32:52.780
amount of curve he was no longer afraid of the smother hook after practicing it

665
00:32:52.780 --> 00:32:53.640
for the rest of

666
00:32:53.640 --> 00:33:02.070
the session okay so he had been working on the supination and we added the axis

667
00:33:02.070 --> 00:33:03.000
tilt and the

668
00:33:03.000 --> 00:33:08.680
difference between the two now his iron swing and his driver swing the release

669
00:33:08.680 --> 00:33:10.040
looks very similar

670
00:33:10.040 --> 00:33:15.050
but the important thing is it looks similar because he's now doing different

671
00:33:15.050 --> 00:33:16.200
things if you were to

672
00:33:16.200 --> 00:33:21.080
now use some of this information that you've been presented with take a look at

673
00:33:21.080 --> 00:33:22.120
the location of his

674
00:33:22.120 --> 00:33:25.460
upper body compared to either the golf ball or compared to the pelvis and you

675
00:33:25.460 --> 00:33:26.200
can see that they're

676
00:33:26.200 --> 00:33:31.680
pretty much on top of each other just a slight tilt away now over here with the

677
00:33:31.680 --> 00:33:32.760
driver we can

678
00:33:32.760 --> 00:33:37.150
or with the afterversion we can see that that right shoulder is well behind the

679
00:33:37.150 --> 00:33:37.800
golf ball the

680
00:33:37.800 --> 00:33:41.840
chest is behind kind of his right hip he's got a lot more access tilt which

681
00:33:41.840 --> 00:33:43.080
helps produce more of

682
00:33:43.080 --> 00:33:47.830
this flat bottom to the swing now we have a golfer demonstrating some low point

683
00:33:47.830 --> 00:33:49.880
control so this golfer

684
00:33:49.880 --> 00:33:54.570
was uh struggling more with iron consistency was dragging the ball great so

685
00:33:54.570 --> 00:33:57.960
what you'll see here

686
00:33:57.960 --> 00:34:03.440
i'll let this play a couple times is you'll see the club working up quickly

687
00:34:03.440 --> 00:34:05.080
after impact

688
00:34:05.080 --> 00:34:11.840
now i had him in slow motion show me the release that he was training and you

689
00:34:11.840 --> 00:34:12.440
can see that

690
00:34:12.440 --> 00:34:17.810
the low points pretty much in the middle of his stance and then starting to

691
00:34:17.810 --> 00:34:20.520
work up very quickly

692
00:34:21.080 --> 00:34:26.660
right through impact and you can also see that the clubface is uh tending to

693
00:34:26.660 --> 00:34:28.040
stay open we we've

694
00:34:28.040 --> 00:34:33.980
addressed all those issues um with a cluster of drills and i'll show you here

695
00:34:33.980 --> 00:34:35.240
in a second now if

696
00:34:35.240 --> 00:34:38.780
you're not used to seeing that drill of just like a slow motion release here's

697
00:34:38.780 --> 00:34:40.120
a student who has more

698
00:34:40.120 --> 00:34:47.310
of a iron base wing demonstrating kind of the same thing and what you'll we're

699
00:34:47.310 --> 00:34:48.200
doing the same

700
00:34:48.200 --> 00:34:53.430
drill i should say and what you'll see is that his tendency is to have the club

701
00:34:53.430 --> 00:34:54.040
working

702
00:34:54.040 --> 00:34:58.750
much more high to low where the golfer previously was having much more low to

703
00:34:58.750 --> 00:34:59.160
high

704
00:34:59.160 --> 00:35:05.800
so now after doing a nine a drill called nine to low point that we use on the

705
00:35:05.800 --> 00:35:07.400
site um he was working

706
00:35:07.400 --> 00:35:10.940
on getting without letting his upper body lunge that's why he had the stick

707
00:35:10.940 --> 00:35:11.960
here he was working on

708
00:35:11.960 --> 00:35:16.650
getting the the club to bottom out more in front of the golf ball so now what

709
00:35:16.650 --> 00:35:17.800
you'll tend to see

710
00:35:17.800 --> 00:35:22.490
is a little bit more neutral pattern where the club is coming down through

711
00:35:22.490 --> 00:35:23.000
contact and then

712
00:35:23.000 --> 00:35:27.730
working up on the way through but you'll see that after impact the club is

713
00:35:27.730 --> 00:35:28.920
lower to the ground with

714
00:35:28.920 --> 00:35:35.990
that arm extension it's less of a club working up pattern so here we've got

715
00:35:35.990 --> 00:35:37.480
both versions

716
00:35:39.320 --> 00:35:45.150
we'll try to get them about even after impact you can see this is a little bit

717
00:35:45.150 --> 00:35:45.960
more of that

718
00:35:45.960 --> 00:35:49.800
driver base movement where the club is coming up pretty quickly this is more of

719
00:35:49.800 --> 00:35:50.520
the iron base

720
00:35:50.520 --> 00:35:54.290
movement where he's got a little bit better access tilt and that club working

721
00:35:54.290 --> 00:35:56.280
more down so it doesn't

722
00:35:56.280 --> 00:36:01.960
have to look perfectly but if you make some smart adjustments to your pattern

723
00:36:01.960 --> 00:36:03.640
you can make progress

724
00:36:03.640 --> 00:36:09.770
with either the iron or the driver the next goal is then to uh train going back

725
00:36:09.770 --> 00:36:11.480
and forth between

726
00:36:11.480 --> 00:36:15.280
those two shots so that you have a better success rate of being able to pull it

727
00:36:15.280 --> 00:36:16.120
off on the course

728
00:36:16.120 --> 00:36:21.590
if you struggle with one area of the other i would tend to suggest with the

729
00:36:21.590 --> 00:36:22.280
driver you would

730
00:36:22.280 --> 00:36:26.100
want to focus on access tilt the club path as well as the face-to-path

731
00:36:26.100 --> 00:36:27.000
relationship

732
00:36:27.000 --> 00:36:31.710
i use a number of of drills on the website uh frequently to help people with

733
00:36:31.710 --> 00:36:32.920
these concepts

734
00:36:32.920 --> 00:36:36.670
mostly revolving around how the lower body works since it's more of a total

735
00:36:36.670 --> 00:36:37.960
body activity and how

736
00:36:37.960 --> 00:36:42.130
to create the proper access tilt as well as how to release the club with a

737
00:36:42.130 --> 00:36:43.720
little bit more supination

738
00:36:43.720 --> 00:36:48.410
to support more of that loading pattern with iron consistency i'm typically

739
00:36:48.410 --> 00:36:49.240
working on more

740
00:36:49.240 --> 00:36:54.290
low point control or face-to-target relationship so things such as the open

741
00:36:54.290 --> 00:36:55.720
right hand or or

742
00:36:55.720 --> 00:36:58.660
getting a little bit more access tilt and learning where the upper body should

743
00:36:58.660 --> 00:36:59.560
be in space

744
00:36:59.560 --> 00:37:03.240
and potentially tempo drills work really well for this particular problem

745
00:37:03.240 --> 00:37:07.490
but one of the goal standards i go for with low point control is the arm

746
00:37:07.490 --> 00:37:08.280
extension

747
00:37:08.280 --> 00:37:11.420
timing and direction which i i have a number of different videos to help

748
00:37:11.420 --> 00:37:11.880
support
