Grip Strength to Sternum

WEBVTT

1
00:00:00.000 --> 00:00:04.480
In this video, we're going to discuss grip to sternum location.

2
00:00:04.480 --> 00:00:09.120
So I had a question about how guys like John Rom will have a more of a boat

3
00:00:09.120 --> 00:00:10.280
wrist or Jordan

4
00:00:10.280 --> 00:00:11.280
speed.

5
00:00:11.280 --> 00:00:14.830
They'll have a really boat wrist with a weak grip and then how someone like a

6
00:00:14.830 --> 00:00:15.680
Dustin Johnson

7
00:00:15.680 --> 00:00:17.760
will have a boat wrist with a strong grip.

8
00:00:17.760 --> 00:00:23.160
And so how grip orientation relates to the top of the swing position.

9
00:00:23.160 --> 00:00:29.500
Unfortunately, there's not a really clear correlation between starting grip and

10
00:00:29.500 --> 00:00:29.880
top of

11
00:00:29.880 --> 00:00:31.040
the swing position.

12
00:00:31.040 --> 00:00:34.920
But there's a really, really strong, almost intimate relationship between where

13
00:00:34.920 --> 00:00:35.600
the sternum

14
00:00:35.600 --> 00:00:39.400
is at impact and where the hands are at impact.

15
00:00:39.400 --> 00:00:44.620
And part of that is because there's a very small margin of where the club is

16
00:00:44.620 --> 00:00:45.320
going to

17
00:00:45.320 --> 00:00:50.360
be at impact in order to have a solid, you know, torque quality shot.

18
00:00:50.360 --> 00:00:54.430
And therefore, there are only so many different body and wrist orientations I

19
00:00:54.430 --> 00:00:55.160
could use to

20
00:00:55.160 --> 00:00:56.600
get in that position.

21
00:00:56.600 --> 00:01:00.560
For example, let's say the club is going to be just slightly leaning forward,

22
00:01:00.560 --> 00:01:00.960
kind of

23
00:01:00.960 --> 00:01:02.240
roughly like this.

24
00:01:02.240 --> 00:01:06.540
If I was to get my body in a good tour impact position and then put my hands on

25
00:01:06.540 --> 00:01:07.640
the club,

26
00:01:07.640 --> 00:01:11.560
there are only so many different ways you'll see in order to get some of these

27
00:01:11.560 --> 00:01:12.400
orientations

28
00:01:12.400 --> 00:01:15.440
I end up having to move my sternum.

29
00:01:15.440 --> 00:01:20.840
So in order to keep it there, there's a smaller window than you would expect.

30
00:01:20.840 --> 00:01:28.080
So if I take a normal kind of neutral grip, about 25 degrees of extension of

31
00:01:28.080 --> 00:01:28.880
the lead

32
00:01:28.880 --> 00:01:32.370
wrist and then fairly neutral with that trail wrist, and I get into that tour

33
00:01:32.370 --> 00:01:33.800
impact position,

34
00:01:33.800 --> 00:01:37.190
you'll see that the hands and the lead wrist is naturally going to lose some of

35
00:01:37.190 --> 00:01:37.920
its bow.

36
00:01:37.920 --> 00:01:39.920
It's going to move slightly forward.

37
00:01:39.920 --> 00:01:45.130
The trail wrist is going to increase the amount of extension and the handle

38
00:01:45.130 --> 00:01:46.600
raised just slightly

39
00:01:46.600 --> 00:01:48.640
as it matches where my sternum is.

40
00:01:48.640 --> 00:01:53.680
Now if I kept my hips in that same good impact position, but then I closed off

41
00:01:53.680 --> 00:01:54.480
my sternum,

42
00:01:54.480 --> 00:02:03.800
it would be very hard for me to get my hands into that same orientation.

43
00:02:03.800 --> 00:02:07.550
Because if I did, I can feel that it would be very hard for that not to be

44
00:02:07.550 --> 00:02:08.360
coming steep

45
00:02:08.360 --> 00:02:09.440
into the ground.

46
00:02:09.440 --> 00:02:13.240
So what will tend to happen is you'll see a predictable pattern of where the

47
00:02:13.240 --> 00:02:13.960
upper body

48
00:02:13.960 --> 00:02:19.200
is in space and what the hands are doing depending on what they were at setup.

49
00:02:19.200 --> 00:02:24.210
So if you tend to drift your upper body in front, you will tend to have a

50
00:02:24.210 --> 00:02:25.520
little bit more

51
00:02:25.520 --> 00:02:30.960
of extension in that lead wrist, a little bit more neutral trail wrist.

52
00:02:30.960 --> 00:02:33.850
So you're not going to come in with that tour impact position if your upper

53
00:02:33.850 --> 00:02:34.240
body is

54
00:02:34.240 --> 00:02:38.240
lunged because the club would just slam into the ground.

55
00:02:38.240 --> 00:02:44.310
So in order to shallow it out, what you'll tend to see is that that lead wrist

56
00:02:44.310 --> 00:02:45.080
is going

57
00:02:45.080 --> 00:02:48.840
to extend and that trail wrist is going to flex to give me a little bit more

58
00:02:48.840 --> 00:02:49.320
kind of

59
00:02:49.320 --> 00:02:52.200
flat spot at the bottom of the swing.

60
00:02:52.200 --> 00:02:55.720
This is what my work with though, so it affects consistency.

61
00:02:55.720 --> 00:02:59.660
Conversely if I'm a little bit more let's say upper body way behind kind of

62
00:02:59.660 --> 00:03:00.480
like this,

63
00:03:00.480 --> 00:03:05.760
if I was to extend, if I was on a good path and I was to extend that lead wrist

64
00:03:05.760 --> 00:03:06.120
, I would

65
00:03:06.120 --> 00:03:08.000
bottom out unless I stood up.

66
00:03:08.000 --> 00:03:14.420
So oftentimes you'll see this back and up can accompany that extension of the

67
00:03:14.420 --> 00:03:15.560
lead wrist.

68
00:03:15.560 --> 00:03:21.680
But if I was to just be back and not stand up, you'll tend to see a fair amount

69
00:03:21.680 --> 00:03:23.160
of exaggeration

70
00:03:23.160 --> 00:03:27.290
of flexing that lead wrist and extending that trail wrist in order to avoid

71
00:03:27.290 --> 00:03:29.680
hitting it fat.

72
00:03:29.680 --> 00:03:32.040
Kind of a little bit more of the white movement.

73
00:03:32.040 --> 00:03:35.960
So what we'll do for the rest of this video is we're going to go through and

74
00:03:35.960 --> 00:03:36.560
look at some

75
00:03:36.560 --> 00:03:41.720
examples of different sternum locations and grip combinations.

76
00:03:41.720 --> 00:03:47.910
Because what you'll see is at the tour level, the golfers who have a weaker

77
00:03:47.910 --> 00:03:49.160
lead hand tend

78
00:03:49.160 --> 00:03:52.080
to have a lot of bowing at impact.

79
00:03:52.080 --> 00:03:57.290
So if a weak wrist is going to be pretty close to neutral, so kind of like this

80
00:03:57.290 --> 00:03:57.840
, you will

81
00:03:57.840 --> 00:04:06.160
tend to see somewhere in that 35, 40 degrees of bowing of that lead wrist.

82
00:04:06.160 --> 00:04:13.240
So really, motorcycling like crazy, like a John Rahm, that's harder to do.

83
00:04:13.240 --> 00:04:17.800
Like a John Rahm, like a Jordan speed, really like a Will McKenzie.

84
00:04:17.800 --> 00:04:24.830
So weaker grip and then really bowing, really bowing, that was better, really b

85
00:04:24.830 --> 00:04:25.840
owing in order

86
00:04:25.840 --> 00:04:31.440
to help control that strike and match up a little bit better body position.

87
00:04:31.440 --> 00:04:36.250
If what you'll tend to see with the stronger lead hand is there's a couple

88
00:04:36.250 --> 00:04:37.760
different options.

89
00:04:37.760 --> 00:04:41.960
So it allows you to not have quite as much of that bow.

90
00:04:41.960 --> 00:04:47.540
You can kind of keep it a little bit more in a, or closer to keeping it in that

91
00:04:47.540 --> 00:04:48.320
starting

92
00:04:48.320 --> 00:04:49.880
position as you rotate through.

93
00:04:49.880 --> 00:04:54.210
They'll tend to still bow it, even the ones who are slightly extended, but just

94
00:04:54.210 --> 00:04:54.600
not as

95
00:04:54.600 --> 00:04:55.760
much.

96
00:04:55.760 --> 00:05:00.430
But the other option is there are some guys who start strong and then bow it

97
00:05:00.430 --> 00:05:01.440
like crazy,

98
00:05:01.440 --> 00:05:06.950
but that allows them to really power it with the body, really kind of side bend

99
00:05:06.950 --> 00:05:07.720
, rotate

100
00:05:07.720 --> 00:05:12.230
and get underneath it and have a really late flat spot, tend to work really

101
00:05:12.230 --> 00:05:13.040
well, become

102
00:05:13.040 --> 00:05:15.160
very good drivers of the golf ball.

103
00:05:15.160 --> 00:05:20.090
So we'll take a look at some different examples, hopefully that'll help clarify

104
00:05:20.090 --> 00:05:20.840
where your

105
00:05:20.840 --> 00:05:24.500
grip is at impact and what your body's doing, because it may help you

106
00:05:24.500 --> 00:05:25.720
understand if you're

107
00:05:25.720 --> 00:05:28.710
trying to get your body in a slightly different position by powering the swing

108
00:05:28.710 --> 00:05:30.240
slightly differently,

109
00:05:30.240 --> 00:05:33.540
what your wrist and what your arms are going to have to do in order to

110
00:05:33.540 --> 00:05:34.400
accommodate.

111
00:05:34.400 --> 00:05:36.880
So I thought it would be helpful to look at some examples.

112
00:05:36.880 --> 00:05:38.720
We're going to use two major references.

113
00:05:38.720 --> 00:05:42.160
We're going to look at where is the upper body in space.

114
00:05:42.160 --> 00:05:45.830
For that we're going to use the reference of the sternum, but we'll see more of

115
00:05:45.830 --> 00:05:46.160
that

116
00:05:46.160 --> 00:05:47.680
from the down the line.

117
00:05:47.680 --> 00:05:51.200
And from the face on view, we'll be able to see the strength of the grip at

118
00:05:51.200 --> 00:05:51.760
setup.

119
00:05:51.760 --> 00:05:57.200
So where is, how much extension do we have in that lead wrist or in the weak

120
00:05:57.200 --> 00:05:57.880
grips, how

121
00:05:57.880 --> 00:06:02.670
much flexion and how much has that changed to impact, or looking at where the

122
00:06:02.670 --> 00:06:03.160
Vs are

123
00:06:03.160 --> 00:06:07.440
pointing at setup that can be helpful as well.

124
00:06:07.440 --> 00:06:13.300
So both of these golfers have stronger left hand grips, Dustin definitely has a

125
00:06:13.300 --> 00:06:14.120
stronger

126
00:06:14.120 --> 00:06:19.340
right hand grip, but Matt Coocher has more of a neutral right hand grip to

127
00:06:19.340 --> 00:06:20.240
accompany

128
00:06:20.240 --> 00:06:23.160
that strong left hand.

129
00:06:23.160 --> 00:06:29.640
So what we'll do is we'll take them from setup to impact, and we can see that

130
00:06:29.640 --> 00:06:30.360
Dustin

131
00:06:30.360 --> 00:06:35.580
had a lot of extension in his lead wrist at setup, and then at impact it's

132
00:06:35.580 --> 00:06:36.960
pretty much

133
00:06:36.960 --> 00:06:37.960
flat.

134
00:06:37.960 --> 00:06:42.740
So he's flexed his lead wrist a good amount, and he's accompanied that with a

135
00:06:42.740 --> 00:06:43.560
fair amount

136
00:06:43.560 --> 00:06:44.560
of body rotation.

137
00:06:44.560 --> 00:06:48.720
We can see that his chest or sternum is pointing well out in front of the golf

138
00:06:48.720 --> 00:06:49.320
ball.

139
00:06:49.320 --> 00:06:52.800
That'll be easier to see when we look at it from down the line.

140
00:06:52.800 --> 00:06:56.220
So now if we see Matt Coocher, we can just take a snapshot of how much

141
00:06:56.220 --> 00:06:58.360
extension he has

142
00:06:58.360 --> 00:07:06.300
at setup, and then when we get him to impact, we can see that he's got less

143
00:07:06.300 --> 00:07:08.000
extension.

144
00:07:08.000 --> 00:07:13.830
So you can see that he has flexed his lead wrist a little bit, but you can see

145
00:07:13.830 --> 00:07:14.440
that there's

146
00:07:14.440 --> 00:07:15.960
still some angle there.

147
00:07:15.960 --> 00:07:23.520
So he's closer to where he was at setup than say Dustin Johnson, who has bode

148
00:07:23.520 --> 00:07:24.600
it a lot more.

149
00:07:24.600 --> 00:07:28.670
We'll be able to see and understand why a lot easier when we take a look at it

150
00:07:28.670 --> 00:07:29.080
from

151
00:07:29.080 --> 00:07:31.240
down the line.

152
00:07:31.240 --> 00:07:34.980
So now if we take a look from down the line, the amount of rotation of where

153
00:07:34.980 --> 00:07:35.680
the sternum

154
00:07:35.680 --> 00:07:38.640
is is going to be a lot easier to see.

155
00:07:38.640 --> 00:07:44.270
So from the face on view, we'll have a better view of how strong or how weak

156
00:07:44.270 --> 00:07:45.480
the grip actually

157
00:07:45.480 --> 00:07:50.200
is, but from looking at impact position, if we kind of imagine almost

158
00:07:50.200 --> 00:07:51.400
perpendicular to

159
00:07:51.400 --> 00:07:56.610
the spine, you can see that Matt Coocher's sternum would be pointing kind of

160
00:07:56.610 --> 00:07:57.120
just out

161
00:07:57.120 --> 00:08:00.500
in front of the golf ball, where Dustin Johnson, when hitting this drive, has

162
00:08:00.500 --> 00:08:01.400
his sternum pointing

163
00:08:01.400 --> 00:08:03.520
way out in front of the golf ball.

164
00:08:03.520 --> 00:08:07.560
And now makes sense seeing how open he got his sternum that he could have such

165
00:08:07.560 --> 00:08:08.080
a strong

166
00:08:08.080 --> 00:08:16.010
grip, but have it bode at the top of the swing and still fairly flat or much

167
00:08:16.010 --> 00:08:17.160
more bode than

168
00:08:17.160 --> 00:08:18.680
it was at setup.

169
00:08:18.680 --> 00:08:23.010
Because the bowing of the lead wrist closes the club face, having a stronger

170
00:08:23.010 --> 00:08:23.640
lead hand

171
00:08:23.640 --> 00:08:28.680
closes the club face, but then that is balanced out by the amount of rotation.

172
00:08:28.680 --> 00:08:34.430
So Matt Coocher doesn't bow as much, but had it closed because of the strong

173
00:08:34.430 --> 00:08:36.240
grip at setup.

174
00:08:36.240 --> 00:08:40.500
And so given the amount of body rotation that he has, he's able to match up the

175
00:08:40.500 --> 00:08:41.840
club face

176
00:08:41.840 --> 00:08:47.390
without having to bow that lead hand quite as much as someone like Dustin

177
00:08:47.390 --> 00:08:48.400
Johnson.

178
00:08:48.400 --> 00:08:52.660
So we'll take a look at someone who gets into a body position closer to Dustin

179
00:08:52.660 --> 00:08:53.360
Johnson,

180
00:08:53.360 --> 00:08:58.850
that does so with a weaker grip so that you can see what kind of wrist and arm

181
00:08:58.850 --> 00:08:59.760
movements

182
00:08:59.760 --> 00:09:02.600
they'll have to do to compensate.

183
00:09:02.600 --> 00:09:07.280
So here we, on the right we can see a John Rahm setup position.

184
00:09:07.280 --> 00:09:11.880
You can see that that left wrist is in a fairly neutral position or the V on

185
00:09:11.880 --> 00:09:12.680
that thumb is

186
00:09:12.680 --> 00:09:14.320
pointing well out here.

187
00:09:14.320 --> 00:09:18.470
And you won't see too many guys with a really weak trail hand, but you'll see

188
00:09:18.470 --> 00:09:19.340
that his trail

189
00:09:19.340 --> 00:09:23.880
hand is in a weaker position than someone like Dustin Johnson that we saw

190
00:09:23.880 --> 00:09:24.720
earlier.

191
00:09:24.720 --> 00:09:30.000
And so what we'll see is as he gets towards impact, what we'll see from the

192
00:09:30.000 --> 00:09:30.960
down the line

193
00:09:30.960 --> 00:09:34.380
is that he has a fair amount of rotation and side bend.

194
00:09:34.380 --> 00:09:38.640
And so to accommodate that he's going to have a significant amount of bend of

195
00:09:38.640 --> 00:09:39.260
that lead

196
00:09:39.260 --> 00:09:45.420
wrist and extension of his trail wrist, even as he gets really close to impact.

197
00:09:45.420 --> 00:09:50.740
So if you're going to have a weak grip, what you'll see is that you pretty much

198
00:09:50.740 --> 00:09:51.340
have to

199
00:09:51.340 --> 00:09:56.550
have a significant amount of bow in order to get anywhere near a toward impact

200
00:09:56.550 --> 00:09:57.540
position.

201
00:09:57.540 --> 00:10:02.970
But if you have a strong grip, you can either bow like Dustin Johnson or keep

202
00:10:02.970 --> 00:10:03.980
the wrist in

203
00:10:03.980 --> 00:10:08.460
a little bit closer to the same position as setup, similar to what we saw with

204
00:10:08.460 --> 00:10:10.740
Matt Coocher.

205
00:10:10.740 --> 00:10:15.330
So now if we take John Rahm and get him close to impact, we're actually, we can

206
00:10:15.330 --> 00:10:15.980
probably

207
00:10:15.980 --> 00:10:21.900
get him right at impact, you'll see that we've got a similar looking sternum

208
00:10:21.900 --> 00:10:23.020
position.

209
00:10:23.020 --> 00:10:27.280
You'll see that Dustin's a little bit more open, but you'll see that for all

210
00:10:27.280 --> 00:10:27.780
intent and

211
00:10:27.780 --> 00:10:31.260
purposes, you can see about the same amount of the rib cage.

212
00:10:31.260 --> 00:10:33.660
You can see it's kind of on about the same tilt.

213
00:10:33.660 --> 00:10:37.830
Their legs and pelvis have done a little different, but we can see that the rib

214
00:10:37.830 --> 00:10:38.940
cage or the sternum,

215
00:10:38.940 --> 00:10:43.300
which is our reference point, is in a closest position.

216
00:10:43.300 --> 00:10:49.050
So they've used their grips to get the club back to kind of a similar position,

217
00:10:49.050 --> 00:10:49.620
and the

218
00:10:49.620 --> 00:10:55.130
way they did it is Dustin Johnson had a stronger grip and then bow to fair

219
00:10:55.130 --> 00:10:56.420
amount, John Rahm

220
00:10:56.420 --> 00:11:01.740
had a weak grip and bowed a ton.

221
00:11:01.740 --> 00:11:04.940
So looking at the top of the swing, we can see how two different grip

222
00:11:04.940 --> 00:11:05.940
attachments were

223
00:11:05.940 --> 00:11:10.240
able to get to about the same top of the backswing position for the wrist as

224
00:11:10.240 --> 00:11:12.060
far as that amount

225
00:11:12.060 --> 00:11:14.560
of flex of that lead wrist.

226
00:11:14.560 --> 00:11:19.770
Now Dustin has a much bigger shoulder turn, much more vertical arm movement

227
00:11:19.770 --> 00:11:20.380
than John

228
00:11:20.380 --> 00:11:25.400
Rahm, but you'll see that they both get into this flex position with that lead

229
00:11:25.400 --> 00:11:26.180
wrist.

230
00:11:26.180 --> 00:11:31.140
That flex position of the lead wrist is going to be somewhat of an indicator

231
00:11:31.140 --> 00:11:32.060
that they're

232
00:11:32.060 --> 00:11:37.270
going to use their body for rotation, because you're not going to be able, that

233
00:11:37.270 --> 00:11:37.900
's going

234
00:11:37.900 --> 00:11:43.110
to, with the wrist in a flex position like that, it's going to feel very weak

235
00:11:43.110 --> 00:11:43.660
to pull

236
00:11:43.660 --> 00:11:50.370
down with the arms, but it's going to feel very strong if I'm rotating my arms

237
00:11:50.370 --> 00:11:51.100
around

238
00:11:51.100 --> 00:11:52.100
my body.

239
00:11:52.100 --> 00:11:55.250
So if I'm using my body as more of the power source, you'll tend to gravitate

240
00:11:55.250 --> 00:11:57.300
towards that

241
00:11:57.300 --> 00:12:02.730
bowed position, regardless of whether it's in a weak or a strong set up

242
00:12:02.730 --> 00:12:04.220
position, where

243
00:12:04.220 --> 00:12:08.220
if I'm more of an arm puller, I will tend to gravitate more towards a little

244
00:12:08.220 --> 00:12:08.620
bit of

245
00:12:08.620 --> 00:12:11.380
that extension.

246
00:12:11.380 --> 00:12:14.680
There's obvious exceptions to that rule, but that's a general tendency that I

247
00:12:14.680 --> 00:12:14.940
tend

248
00:12:14.940 --> 00:12:19.540
to see when looking at my students or analyzing swings on YouTube.

249
00:12:19.540 --> 00:12:27.770
But again, with the strong grip, Dustin has to bow his wrist a fair amount, but

250
00:12:27.770 --> 00:12:28.380
with

251
00:12:28.380 --> 00:12:32.150
a weak grip in order to get the club face to continue closing, you'll see Jon

252
00:12:32.150 --> 00:12:32.580
Rahm has

253
00:12:32.580 --> 00:12:37.900
to bow it even more and keep it bowing or bow it much later.

254
00:12:37.900 --> 00:12:44.070
So using that sternum position, we can get a good idea as far as where the club

255
00:12:44.070 --> 00:12:44.860
's going

256
00:12:44.860 --> 00:12:52.380
to be, and knowing what kind of set up position grip orientation they had will

257
00:12:52.380 --> 00:12:53.300
give you a

258
00:12:53.300 --> 00:12:57.260
good idea as far as what kind of wrist movements or what orientations you're

259
00:12:57.260 --> 00:12:57.980
going to have

260
00:12:57.980 --> 00:12:59.500
to have an impact.

261
00:12:59.500 --> 00:13:03.790
Where this is really helpful for you is if you're trying to get your body to

262
00:13:03.790 --> 00:13:04.300
rotate

263
00:13:04.300 --> 00:13:09.080
more open, you might want to look at how your grip is affecting your impact

264
00:13:09.080 --> 00:13:09.980
position, or

265
00:13:09.980 --> 00:13:12.620
if you're trying to get more side bend or if you're trying to stay behind the

266
00:13:12.620 --> 00:13:14.100
golf ball,

267
00:13:14.100 --> 00:13:18.460
understanding how the grip relates to that body position may help you eliminate

268
00:13:18.460 --> 00:13:19.060
a barrier

269
00:13:19.060 --> 00:13:21.580
from what you're trying to train.

270
00:13:21.580 --> 00:13:27.920
So now over on the left we have Rod Pampling, and we can see a very weak left

271
00:13:27.920 --> 00:13:28.940
hand grip,

272
00:13:28.940 --> 00:13:34.100
but he's not going to get in nearly as open a position as Jon Rahm.

273
00:13:34.100 --> 00:13:40.680
What we'll see instead is he's going to have a slight amount of flex compared

274
00:13:40.680 --> 00:13:41.340
to someone

275
00:13:41.340 --> 00:13:47.680
like Jon Rahm, which we saw impact had a pretty significant amount of lead

276
00:13:47.680 --> 00:13:49.260
wrist flexion.

277
00:13:49.260 --> 00:13:54.220
So again, you can use this to help you figure out what combination is going to

278
00:13:54.220 --> 00:13:54.980
work best

279
00:13:54.980 --> 00:13:55.980
for you.

280
00:13:55.980 --> 00:13:59.860
If you don't feel very powerful with a lot of lead wrist flex, then you might

281
00:13:59.860 --> 00:14:00.260
want to

282
00:14:00.260 --> 00:14:04.960
have a stronger grip, or you're not going to get as open as someone like a Jon

283
00:14:04.960 --> 00:14:05.340
Rahm

284
00:14:05.340 --> 00:14:07.100
or Dustin Johnson.

285
00:14:07.100 --> 00:14:10.780
We'll see that when we take a look at Rod when we look at his down the line.

286
00:14:10.780 --> 00:14:17.120
So here he is now, and we'll see as he gets towards the top of the swing, he

287
00:14:17.120 --> 00:14:17.580
goes into

288
00:14:17.580 --> 00:14:19.260
that flexion pattern.

289
00:14:19.260 --> 00:14:22.810
So he's not really doing it to set the top of the swing, but he's going to

290
00:14:22.810 --> 00:14:23.460
start that

291
00:14:23.460 --> 00:14:27.420
flexion pattern pretty early in the downswing because he's a little bit more of

292
00:14:27.420 --> 00:14:28.620
a body puller.

293
00:14:28.620 --> 00:14:33.640
So you'll see he gets a fair amount of bow, not a ton, not nearly as much as

294
00:14:33.640 --> 00:14:34.340
Jon Rahm

295
00:14:34.340 --> 00:14:37.620
or Dustin Johnson, but more than say Matt Coocher.

296
00:14:37.620 --> 00:14:42.850
And so we'll see that we saw from the face on view, he had a little bit of lead

297
00:14:42.850 --> 00:14:43.420
wrist

298
00:14:43.420 --> 00:14:45.820
flexion compared to his setup grip.

299
00:14:45.820 --> 00:14:51.030
We can see that at impact, he doesn't have his body nearly as open, rotated or

300
00:14:51.030 --> 00:14:52.100
side bend

301
00:14:52.100 --> 00:14:53.620
as someone like Jon Rahm.

302
00:14:53.620 --> 00:14:58.210
So you'll start to see this pattern of the more you can see of their ribcage,

303
00:14:58.210 --> 00:14:58.820
the more

304
00:14:58.820 --> 00:15:02.860
that sternum is behind the golf ball and pointing out in front of it.

305
00:15:02.860 --> 00:15:07.300
So rotated and side bend, the more that you're going to have to have either a

306
00:15:07.300 --> 00:15:08.780
stronger grip

307
00:15:08.780 --> 00:15:12.820
or a flex lead wrist or often both.

308
00:15:12.820 --> 00:15:16.020
So now we have another example looking at Zach Johnson.

309
00:15:16.020 --> 00:15:20.840
So you can look at his setup grip here from the face on video and then we can

310
00:15:20.840 --> 00:15:21.460
look at

311
00:15:21.460 --> 00:15:25.340
his impact position from down the line and it'll start to make sense.

312
00:15:25.340 --> 00:15:31.530
So we can see that his upper body isn't dramatically open, it's relatively shut

313
00:15:31.530 --> 00:15:32.300
compared to a

314
00:15:32.300 --> 00:15:34.780
lot of strong grip players.

315
00:15:34.780 --> 00:15:38.410
So we're going to expect, based on that fact alone, that he's not going to be

316
00:15:38.410 --> 00:15:39.620
one of those

317
00:15:39.620 --> 00:15:42.980
golfers that have a whole lot of bow in his wrist.

318
00:15:42.980 --> 00:15:48.190
We can also see that when we get up towards the top of the swing, you'll see

319
00:15:48.190 --> 00:15:48.860
that if I

320
00:15:48.860 --> 00:15:53.390
scrub back and forth, you'll see his shoulders and his arms kind of creating

321
00:15:53.390 --> 00:15:54.140
more of the

322
00:15:54.140 --> 00:15:57.420
speed through the early part of the downswing.

323
00:15:57.420 --> 00:16:03.130
So it would make sense that we wouldn't see a massive bowing at the top of the

324
00:16:03.130 --> 00:16:03.860
swing the

325
00:16:03.860 --> 00:16:09.180
way we would see with a more body driven swing or someone who gets more open at

326
00:16:09.180 --> 00:16:10.020
impact.

327
00:16:10.020 --> 00:16:11.020
So let's confirm.

328
00:16:11.020 --> 00:16:16.390
We take a look at the face on camera here, we saw he has a stronger grip and as

329
00:16:16.390 --> 00:16:17.060
he gets

330
00:16:17.060 --> 00:16:23.140
back towards impact, you'll see that the wrist has slightly more flex to it but

331
00:16:23.140 --> 00:16:23.460
not

332
00:16:23.460 --> 00:16:28.160
a drastic amount compared to some of the other guys that we've seen in this

333
00:16:28.160 --> 00:16:28.860
video.

334
00:16:28.860 --> 00:16:34.490
So now we can take a look at a few amateur submissions to kind of see how this

335
00:16:34.490 --> 00:16:34.940
fits in

336
00:16:34.940 --> 00:16:36.980
non-classic toward models.

337
00:16:36.980 --> 00:16:41.530
So here we have a golfer at impact, we can see that his chest is higher than we

338
00:16:41.530 --> 00:16:41.940
were

339
00:16:41.940 --> 00:16:46.300
seeing with some of the other golfers and facing the golf ball.

340
00:16:46.300 --> 00:16:51.230
So we know that that should either be accompanied by a weak grip with a little

341
00:16:51.230 --> 00:16:52.100
bit of bow or

342
00:16:52.100 --> 00:16:58.340
a strong grip with pretty much no noticeable change.

343
00:16:58.340 --> 00:17:04.010
So here we have more of a neutral grip possibly getting into that stronger

344
00:17:04.010 --> 00:17:05.140
category.

345
00:17:05.140 --> 00:17:10.100
So we'll expect to see not a lot of bow as he gets towards impact and you'll

346
00:17:10.100 --> 00:17:10.740
see that

347
00:17:10.740 --> 00:17:16.340
that wrist is fairly flat or slightly extended as he gets towards impact.

348
00:17:16.340 --> 00:17:23.700
We'll also see that his upper body has a little bit of lunge so that lunge of

349
00:17:23.700 --> 00:17:24.900
the upper body

350
00:17:24.900 --> 00:17:32.660
moving forward will also decrease the need to have flexion in the lead wrist.

351
00:17:32.660 --> 00:17:38.240
So we'll see that this golfer right here, his swing pattern is kind of matching

352
00:17:38.240 --> 00:17:38.660
up.

353
00:17:38.660 --> 00:17:43.870
So what that means is if we were to get his upper body to work on a better

354
00:17:43.870 --> 00:17:45.280
impact position,

355
00:17:45.280 --> 00:17:49.200
he'd be staying a little bit more behind it, get a little bit more rotation, he

356
00:17:49.200 --> 00:17:49.280
would

357
00:17:49.280 --> 00:17:53.280
have to add a little bit of flexion to that lead wrist in order to balance it

358
00:17:53.280 --> 00:17:53.760
out and

359
00:17:53.760 --> 00:17:54.760
accommodate.

360
00:17:54.760 --> 00:17:59.020
All right, so one more example, we've got that, you can take a snapshot of the

361
00:17:59.020 --> 00:17:59.520
amount

362
00:17:59.520 --> 00:18:00.920
of extension.

363
00:18:00.920 --> 00:18:07.630
So on the weaker side of neutral, as we go to impact, we can see not a lot of

364
00:18:07.630 --> 00:18:08.800
the sternum

365
00:18:08.800 --> 00:18:11.550
is pointing closer to the golf ball, so not a lot of rotation, we can't see

366
00:18:11.550 --> 00:18:11.960
much of the

367
00:18:11.960 --> 00:18:15.550
rib cage, so we would expect that it's going to come back pretty close to

368
00:18:15.550 --> 00:18:16.360
wherever that

369
00:18:16.360 --> 00:18:18.120
was at setup.

370
00:18:18.120 --> 00:18:22.900
Now, as he goes into a swing, we can see some lateral movement, he does get his

371
00:18:22.900 --> 00:18:23.680
upper body

372
00:18:23.680 --> 00:18:28.040
a little bit more behind it, so that should make it bow just slightly, if this

373
00:18:28.040 --> 00:18:28.560
is a good

374
00:18:28.560 --> 00:18:32.500
shot, and we can see that there's a slight amount of bow, but if he was going

375
00:18:32.500 --> 00:18:32.960
to add

376
00:18:32.960 --> 00:18:37.890
any more body rotation side bend, given that grip strength, we would want to

377
00:18:37.890 --> 00:18:39.200
get more flexion

378
00:18:39.200 --> 00:18:48.520
kind of into that rod pampling zone of amount of flexion.

379
00:18:48.520 --> 00:18:51.520
And one trend you'll see from looking at a lot of the torque rows is that if

380
00:18:51.520 --> 00:18:51.920
you have

381
00:18:51.920 --> 00:18:55.990
a weak grip, there's no way around it, you pretty much have to bow that lead

382
00:18:55.990 --> 00:18:56.480
wrist in

383
00:18:56.480 --> 00:18:59.800
order to get good torque impact conditions.

384
00:18:59.800 --> 00:19:04.300
But if you have a strong grip, you can either bow and use a lot of body

385
00:19:04.300 --> 00:19:05.640
rotation, or not

386
00:19:05.640 --> 00:19:10.270
bow that lead wrist, keep that wrist relatively neutral, and not have as much

387
00:19:10.270 --> 00:19:11.400
body rotation.

388
00:19:11.400 --> 00:19:14.420
But hopefully this video helped you to see kind of the relationship between

389
00:19:14.420 --> 00:19:14.920
where the

390
00:19:14.920 --> 00:19:18.240
body is and impact and how it relates to the grip.

391
00:19:18.240 --> 00:19:22.550
If you stay behind the golf ball and you rotate, you'll need to close the club

392
00:19:22.550 --> 00:19:22.920
face

393
00:19:22.920 --> 00:19:27.720
to accommodate, either with a stronger grip, or bowing the wrist or both.

394
00:19:27.720 --> 00:19:31.550
And if you lunge and if you don't rotate, then you're not going to want to have

395
00:19:31.550 --> 00:19:32.120
a really

396
00:19:32.120 --> 00:19:35.560
flat left wrist or you're going to want to gravitate towards a weaker grip.
