00:00:00.000 --> 00:00:04.200
In this discussion video we're going to take a look at a case study on arm

2
00:00:04.200 --> 00:00:09.680
shallowing. So over on the left we have the B4, this gentleman, submitted this

3
00:00:09.680 --> 00:00:14.760
swing over a year ago and you can see not too bad but you will see that the

4
00:00:14.760 --> 00:00:20.120
arms in general work in a steepish fashion and that the body is extending

5
00:00:20.120 --> 00:00:27.040
installing in order to shallow at the club. This was taken just last week after

6
00:00:27.040 --> 00:00:33.560
about 48 hours of working on that arm shallowing piece and so what you'll see

7
00:00:33.560 --> 00:00:40.220
is there's a very different arm shallowing pattern in this new driver's

8
00:00:40.220 --> 00:00:43.920
swing. What I'm going to do is I'm going to show you the step-by-step little

9
00:00:43.920 --> 00:00:48.760
method that we use to get it and then discuss a little bit at the end why this

10
00:00:48.760 --> 00:00:55.870
movement is challenging and important for golfers to work on. So this member

11
00:00:55.870 --> 00:00:56.520
was

12
00:00:56.520 --> 00:01:00.440
asking for help as far as what he should be working on this winter we discussed

13
00:01:00.440 --> 00:01:03.440
that he's working on his arm shallowing piece and he's been using the

14
00:01:03.440 --> 00:01:08.920
orange whip. So over on the left you will see his swing that he has been

15
00:01:08.920 --> 00:01:13.960
rehearsing in the you know in and around the house and basically what you'll

16
00:01:13.960 --> 00:01:14.160
see

17
00:01:14.160 --> 00:01:20.960
is it's steep with the arm movement and then gets shallow late kind of shallows

18
00:01:20.960 --> 00:01:25.920
starting right about in here. So even though the orange whip is designed to be

19
00:01:25.920 --> 00:01:30.120
kind of a path trainer he was using his normal organization of his shallow

20
00:01:30.120 --> 00:01:30.360
moves.

21
00:01:30.360 --> 00:01:37.850
So then what I did was I asked him to make a backswing while standing vertical.

22
00:01:37.850 --> 00:01:37.920
So

23
00:01:37.920 --> 00:01:41.280
instead of in golf posture just so we could see how much arm shallowing he was

24
00:01:41.280 --> 00:01:45.920
really doing and this is what we'll frequently see which is you can see that

25
00:01:45.920 --> 00:01:50.680
there's a minimal amount of arm shallowing. Yes the club is shallowing but

26
00:01:50.680 --> 00:01:57.400
you'll see that the club is only dropping an inch or so. It's not dropping any

27
00:01:57.400 --> 00:02:02.320
exaggerated amount. So what I did was I looked at some of the 3D numbers just

28
00:02:02.320 --> 00:02:02.400
to

29
00:02:02.400 --> 00:02:09.640
see how much forearm supination amount we have and then based on how much that

30
00:02:09.640 --> 00:02:14.760
forearm is supinating what would the arc length change for this club. And so

31
00:02:14.760 --> 00:02:18.840
basically what I told him was instead of just trying to do it perfectly instead

32
00:02:18.840 --> 00:02:24.160
of just trying to drop it an inch I want you to try to drop it two feet. Okay

33
00:02:24.160 --> 00:02:24.360
so

34
00:02:24.360 --> 00:02:29.880
then after asking him to drop it two feet this was the first iteration and you

35
00:02:29.880 --> 00:02:34.200
can see that the club head didn't really well the club had dropped but it

36
00:02:34.200 --> 00:02:38.360
dropped only because the arms and the hands were dropping. So the whole system

37
00:02:38.360 --> 00:02:43.360
is kind of pulling down not just the club head. So then with a little bit of

38
00:02:43.360 --> 00:02:48.640
practice here's his next attempt and now we can start to see a little bit more

39
00:02:48.640 --> 00:02:55.080
of this two foot drop and so that's a very good looking arm shallow piece if

40
00:02:55.080 --> 00:02:58.480
you're just training the arm shallow then what he does is he gets down into his

41
00:02:58.480 --> 00:03:03.080
golf posture and it looks like it's very exaggerated coming from the inside.

42
00:03:03.080 --> 00:03:07.880
That's a good sign when you're working on this arm shallow piece because when

43
00:03:07.880 --> 00:03:11.200
you start adding body speed and rotation it's naturally going to bring the club

44
00:03:11.200 --> 00:03:18.120
more out towards the target line. So now over on the left is his first attempt

45
00:03:18.120 --> 00:03:22.400
at making a swing while working on that arm shallow piece and you can see that

46
00:03:22.400 --> 00:03:27.640
the club is shallowing out much better than it was in his kind of before video

47
00:03:27.640 --> 00:03:33.720
but you will see that the club face is pointed way up towards the sky. So we

48
00:03:33.720 --> 00:03:36.480
knew that when he went out and played the next day he was probably gonna hit a

49
00:03:36.480 --> 00:03:40.480
bunch of right shots which he did and now he's working around how can I get the

50
00:03:40.480 --> 00:03:46.280
club face to square without bailing on this arm shallow piece. So here was one

51
00:03:46.280 --> 00:03:52.640
of the drives from that next day a mere 24 hours after really kind of diving

52
00:03:52.640 --> 00:03:57.360
into this arm shallow piece and you'll see that the transition is looking like

53
00:03:57.360 --> 00:04:00.400
he's getting the path in a much better position and he actually did a fairly

54
00:04:00.400 --> 00:04:04.120
good job on this particular one of getting the club face relatively square.

55
00:04:04.120 --> 00:04:09.080
You'll see that there is less of that body stall. His body is able to continue

56
00:04:09.080 --> 00:04:13.040
rotating. All these things are good signs for what we want to continue to

57
00:04:13.040 --> 00:04:18.680
work on during the off-season and I want to thank Jason for letting me use this

58
00:04:18.680 --> 00:04:23.680
video to show you kind of the natural progression of working on the arm

59
00:04:23.680 --> 00:04:27.560
shallow piece. So first you want to chunk it and isolate that key movement of

60
00:04:27.560 --> 00:04:31.000
just that arm shallow piece and then you can start reintroducing it into the

61
00:04:31.000 --> 00:04:36.000
swing and adjusting as needed based on ball flight and contact.

62
00:04:36.000 --> 00:04:40.840
So now that you've visually seen the effects of training that shallow moved

63
00:04:40.840 --> 00:04:45.480
just from the forums let's take a look at where that came from. So this graph

64
00:04:45.480 --> 00:04:45.720
is

65
00:04:45.720 --> 00:04:50.480
looking at lead arm pronation and I've got two different golfers over here

66
00:04:50.480 --> 00:04:54.640
on the right we have the demo Steve Alkington so kind of a classic looking

67
00:04:54.640 --> 00:04:59.360
golf swing and then over here on the left we have a higher handicap golfer. So

68
00:04:59.360 --> 00:05:04.080
what you'll frequently see let's start with the Tour Pro is as he approaches

69
00:05:04.080 --> 00:05:09.240
the top of the swing or from the top of the swing into early downswing so I've

70
00:05:09.240 --> 00:05:15.200
it if frozen when he starts to then supinate so when that lead arm starts to

71
00:05:15.200 --> 00:05:19.200
kind of tumble and turn towards the golf ball. What you'll see is from the top

72
00:05:19.200 --> 00:05:24.320
of the swing until here he's going through about 20 degrees of forearm

73
00:05:24.320 --> 00:05:29.520
pronation so that forearm pronation is what is going to help shallow out the

74
00:05:29.520 --> 00:05:35.200
club largely during this transition move. Over on the left we can see a golfer

75
00:05:35.200 --> 00:05:39.320
doing the opposite movement so from the top of the swing there's almost no

76
00:05:39.320 --> 00:05:39.680
shallow

77
00:05:39.680 --> 00:05:44.560
move and then he is going to start supinating or tumbling that club towards

78
00:05:44.560 --> 00:05:49.320
the golf ball pretty much the entire downswing. This is a steep movement and so

79
00:05:49.320 --> 00:05:53.200
he's going to have to stall his body and stand up to shallow it back out where

80
00:05:53.200 --> 00:05:53.280
the

81
00:05:53.280 --> 00:05:57.760
Tour Pro is going to be able to reach that good-looking impact position where

82
00:05:57.760 --> 00:06:04.800
his upper body has continued rotating side bending and not stood up. By running

83
00:06:04.800 --> 00:06:09.960
some numbers what we can see is this 20 degrees of forearm pronation would

84
00:06:09.960 --> 00:06:15.800
cause the golf club if you're swinging a driver to drop about two feet so if

85
00:06:15.800 --> 00:06:18.560
you're swinging a seven iron it'll be a little bit less than that but whenever

86
00:06:18.560 --> 00:06:22.000
you're training it especially if you're coming from this pattern here I like to

87
00:06:22.000 --> 00:06:25.760
exaggerate it and try to air more on the just getting the club to drop about

88
00:06:25.760 --> 00:06:26.320
two

89
00:06:26.320 --> 00:06:30.380
feet while you're working on the shallow move then when you get into golf

90
00:06:30.380 --> 00:06:30.680
foster

91
00:06:30.680 --> 00:06:35.520
it will it will barely look like it's dropping but you'll still be making this

92
00:06:35.520 --> 00:06:39.920
forearm pronation move which is going to shallow out the club during transition

93
00:06:39.920 --> 00:06:39.920
.
