Insight - Keeping The Left Arm Straight?

00:00:00.000 --> 00:00:05.040
In this golf smart insight we're going to look at the optical illusion of the

2
00:00:05.040 --> 00:00:06.860
left arm.

3
00:00:06.860 --> 00:00:12.170
So people have enjoyed some of these optical illusions and essentially all they

4
00:00:12.170 --> 00:00:12.840
are, when

5
00:00:12.840 --> 00:00:16.680
I'm looking at the golf swing I'm typically standing in either the face on or c

6
00:00:16.680 --> 00:00:17.240
addy view

7
00:00:17.240 --> 00:00:19.200
or the down the line view.

8
00:00:19.200 --> 00:00:23.420
And that's not always the best vantage point to see certain movements, one of

9
00:00:23.420 --> 00:00:24.120
which would

10
00:00:24.120 --> 00:00:31.140
be what's happening with the left arm. Basically when I bend a joint or hinge a

11
00:00:31.140 --> 00:00:32.140
joint or whatever

12
00:00:32.140 --> 00:00:37.020
you want to call it, the easiest way to see where or how much I've actually

13
00:00:37.020 --> 00:00:37.720
bent this

14
00:00:37.720 --> 00:00:44.040
joint would be looking perpendicular to the axis that it's moving around.

15
00:00:44.040 --> 00:00:49.060
So essentially when I go up to the top of the swing a lot of people have been

16
00:00:49.060 --> 00:00:49.560
told to

17
00:00:49.560 --> 00:00:54.050
try to keep that left arm straight. Well on 3D I see tour pros who have that

18
00:00:54.050 --> 00:00:54.680
left arm

19
00:00:54.680 --> 00:01:00.610
bending as much as 40 degrees, somewhere 15, 20 degrees is probably normal as

20
00:01:00.610 --> 00:01:01.280
in trying

21
00:01:01.280 --> 00:01:02.840
to keep it straight.

22
00:01:02.840 --> 00:01:07.830
So what ends up happening in the reason that people look different is going to

23
00:01:07.830 --> 00:01:08.480
be based

24
00:01:08.480 --> 00:01:14.180
on the amount of rotation in the shoulder. So if you see, if I can bend my arm

25
00:01:14.180 --> 00:01:14.760
right

26
00:01:14.760 --> 00:01:18.820
about there, so this is going to be my humerus, so that's probably somewhere

27
00:01:18.820 --> 00:01:20.040
around 30 degrees

28
00:01:20.040 --> 00:01:25.030
or so. If I was to take this angle and I'll stiffen my arm so it stays the same

29
00:01:25.030 --> 00:01:25.400
and I

30
00:01:25.400 --> 00:01:29.890
was to rotate it so that now you're looking pretty much straight at it, it's

31
00:01:29.890 --> 00:01:30.600
not going

32
00:01:30.600 --> 00:01:35.220
to look nearly as bent when you're looking straight at it as it would if it

33
00:01:35.220 --> 00:01:37.040
looks perpendicular.

34
00:01:37.040 --> 00:01:41.430
So part of the reason why when you're watching a tour pro swing you don't

35
00:01:41.430 --> 00:01:42.520
really see this

36
00:01:42.520 --> 00:01:48.290
is they tend to have a fair amount of this rotation. So there I'm bending my

37
00:01:48.290 --> 00:01:49.320
arm pretty

38
00:01:49.320 --> 00:01:54.850
good a bit, but I'm also flattening and rotating the shoulder. The reason why a

39
00:01:54.850 --> 00:01:55.760
lot of amateurs

40
00:01:55.760 --> 00:01:58.980
look like they have a fair amount of arm bend is because if you're standing

41
00:01:58.980 --> 00:01:59.800
where the camera

42
00:01:59.800 --> 00:02:06.180
is in this face on view and I move my arms very vertically, you can see I'm now

43
00:02:06.180 --> 00:02:06.680
looking

44
00:02:06.680 --> 00:02:11.050
pretty much straight at this angle compared to if I was a tour pro and I had it

45
00:02:11.050 --> 00:02:11.640
a little

46
00:02:11.640 --> 00:02:18.010
bit more rotated. So keeping your arm straight can help create some width and

47
00:02:18.010 --> 00:02:18.800
there's probably

48
00:02:18.800 --> 00:02:22.310
some good things that could happen, but I've seen tour pros bend it as much as

49
00:02:22.310 --> 00:02:23.280
40 degrees.

50
00:02:23.280 --> 00:02:28.250
So if you're trying to keep your arm straight at least the left one, there's

51
00:02:28.250 --> 00:02:29.140
probably better

52
00:02:29.140 --> 00:02:33.480
ways to accomplish whatever it is that you're trying to do with your golf swing

53
00:02:33.480 --> 00:02:33.880
