00:00:00.000 --> 00:00:04.980
This video is explaining axial velocity so you'll see that I'm a big
2
00:00:04.980 --> 00:00:09.060
proponent of the motorcycle move and kind of getting the face to close. So in
3
00:00:09.060 --> 00:00:13.680
this video we're going to take a look at the 3D graphs that demonstrate axial
4
00:00:13.680 --> 00:00:19.840
velocity. So axial velocity is looking at how fast the club is rotating kind of
5
00:00:19.840 --> 00:00:25.200
like so. When it opens you'll see the line go negative and when it closes you
6
00:00:25.200 --> 00:00:25.320
'll
7
00:00:25.320 --> 00:00:29.400
see the line go positive. So the club will be like this and then naturally in
8
00:00:29.400 --> 00:00:32.120
the backswing I'll have a little bit of opening you'll see it go negative and
9
00:00:32.120 --> 00:00:36.280
then you'll see very different patterns for how the club closes during the
10
00:00:36.280 --> 00:00:41.280
downswing. One of the trends that you will see with tour pros is that they tend
11
00:00:41.280 --> 00:00:47.080
to close it faster earlier which is why I'm a big fan of this motorcycle
12
00:00:47.080 --> 00:00:51.080
movement or getting the club face to start closing either as I'm ending the
13
00:00:51.080 --> 00:00:56.640
backswing or as I'm starting the downswing. A common amateur issue is you'll
14
00:00:56.640 --> 00:01:01.680
see almost virtually no club face closing until it gets down to about here and
15
00:01:01.680 --> 00:01:06.480
then you'll have to close it very quickly. My background from other sports has
16
00:01:06.480 --> 00:01:13.200
taught me that having smooth movements tends to work better than having complex
17
00:01:13.200 --> 00:01:17.800
or rapid movements. So just like when I was learning tennis or when I was
18
00:01:17.800 --> 00:01:18.360
playing
19
00:01:18.360 --> 00:01:22.350
competitive tennis you would want kind of this feeling of a smooth release
20
00:01:22.350 --> 00:01:22.560
where
21
00:01:22.560 --> 00:01:26.600
the ball got hit in the middle. For the same reason I like to have this kind of
22
00:01:26.600 --> 00:01:31.320
smooth gradual closing of the club face the entire downswing instead of having
23
00:01:31.320 --> 00:01:37.040
it stay open for most of it and then close down to the bottom. So as you're
24
00:01:37.040 --> 00:01:40.680
looking through the graphs try to imagine how the swing would look but the
25
00:01:40.680 --> 00:01:40.920
graphs
26
00:01:40.920 --> 00:01:44.520
are going to show the actual rate of how fast that club face is closing during
27
00:01:44.520 --> 00:01:50.600
the golf swing. Okay so now we have an example of an axial velocity graph so
28
00:01:50.600 --> 00:01:55.980
the position I have right here is where they are in space at this green line.
29
00:01:55.980 --> 00:01:56.160
So
30
00:01:56.160 --> 00:02:00.560
roughly around when they start really pouring on the motorcycle movement. This
31
00:02:00.560 --> 00:02:05.320
graph is a timeline of a golf swing so the first line represents a dress this
32
00:02:05.320 --> 00:02:10.480
is top of the swing this is impact and then finish. The further away from this
33
00:02:10.480 --> 00:02:14.200
horizontal black line the faster it's moving so if it's negative it down way
34
00:02:14.200 --> 00:02:17.720
down here it will be rotating open quickly and the higher up it is the
35
00:02:17.720 --> 00:02:22.800
faster it's closing. So basically what you see is not a lot of rotation during
36
00:02:22.800 --> 00:02:26.640
the takeaway pretty much one piece little openings in closing during the
37
00:02:26.640 --> 00:02:31.960
backswing but mostly opening and then you'll see right around here before the
38
00:02:31.960 --> 00:02:35.720
top of the swing before the club changes the direction he's going to start
39
00:02:35.720 --> 00:02:36.520
closing
40
00:02:36.520 --> 00:02:39.840
the club face closes it more rapidly and then right about here it really takes
41
00:02:39.840 --> 00:02:44.000
off and he starts closing the face so that's right around this point in time
42
00:02:44.000 --> 00:02:48.840
in space is when that point in time on the graph happens to occur. It'll make
43
00:02:48.840 --> 00:02:52.160
more sense or it'll be easier to visualize when we take a look at a few
44
00:02:52.160 --> 00:02:57.600
others both pros and amateurs. Okay so here's another pro you'll see he has a
45
00:02:57.600 --> 00:03:02.240
little bit more of the opening during the backswing and during early
46
00:03:02.240 --> 00:03:06.600
transition but you'll see right around here he starts closing it and then right
47
00:03:06.600 --> 00:03:12.160
about where I have it in time and space so well well up here soon after he
48
00:03:12.160 --> 00:03:16.800
started the the downswing sequence he's now gonna start ramping up you'll see a
49
00:03:16.800 --> 00:03:22.720
bigger difference when we get to comparing the three amateurs. Okay here's one
50
00:03:22.720 --> 00:03:22.920
more
51
00:03:22.920 --> 00:03:27.680
pro you can see fairly flat during takeaway opening during the backswing
52
00:03:27.680 --> 00:03:34.900
starts closing there's in order to kind of hinge the wrists in transition you
53
00:03:34.900 --> 00:03:34.960
'll
54
00:03:34.960 --> 00:03:39.560
see typically a little bit of this dip and then right around this point in time
55
00:03:39.560 --> 00:03:43.560
somewhere here you can see that's well above where most of you may be thinking
56
00:03:43.560 --> 00:03:47.200
about closing the club face this is when he's actually starting to rotate the
57
00:03:47.200 --> 00:03:51.640
club face closed now remember if you start closing the club face early and it
58
00:03:51.640 --> 00:03:55.640
causes the ball to hook it means that there's other things going on and you
59
00:03:55.640 --> 00:04:01.280
holding the club face open is kind of a contribution to your overall pattern so
60
00:04:01.280 --> 00:04:05.200
now we've got all three pros on screen you can kind of take a look you can
61
00:04:05.200 --> 00:04:09.190
pause the video and look for some of the details but you can see in general
62
00:04:09.190 --> 00:04:09.640
that
63
00:04:09.640 --> 00:04:14.120
they are starting to close the club face while the club is still well up in in
64
00:04:14.120 --> 00:04:21.520
the air or just after they've started to transition. Now this is the first of
65
00:04:21.520 --> 00:04:26.440
the three amateurs so you'll see a slightly different pattern not too
66
00:04:26.440 --> 00:04:28.880
dissimilar in the backswing maybe a little bit more opening during the
67
00:04:28.880 --> 00:04:32.960
takeaway but then you'll see this flat line through transition where
68
00:04:32.960 --> 00:04:36.880
basically there's no rotation of the club and then you'll actually see it open
69
00:04:36.880 --> 00:04:41.960
well into the downswing you'll see he's now down to about belly button height
70
00:04:41.960 --> 00:04:45.440
where the others were up at kind of eye height or shoulder height or however
71
00:04:45.440 --> 00:04:45.560
you
72
00:04:45.560 --> 00:04:50.600
want to look at it and he still has not started to close yet this is right
73
00:04:50.600 --> 00:04:53.800
about when he's going to start closing the club face so you'll see that he
74
00:04:53.800 --> 00:04:58.040
doesn't have nearly as much time to rotate the club face closed so he's gonna
75
00:04:58.040 --> 00:05:02.840
have to do it very quickly in order to get it in the same orientation. Here's
76
00:05:02.840 --> 00:05:07.600
another amateur so we can see opening and then that same little flat line
77
00:05:07.600 --> 00:05:11.600
during transition you can see it's not until well down here that he starts to
78
00:05:11.600 --> 00:05:15.840
close the club face so this is a common pattern that we're gonna see with a lot
79
00:05:15.840 --> 00:05:20.840
of amateurs who struggle with their transition and release this is kind of
80
00:05:20.840 --> 00:05:25.360
one of those graphs that kind of tells a lot of the story as to why their swing
81
00:05:25.360 --> 00:05:31.160
may be being built the way that it is. And then lastly this is a scratch golfer
82
00:05:31.160 --> 00:05:38.160
a very very good very accomplished amateur so you'll see a still a kind of
83
00:05:38.160 --> 00:05:43.360
flat line with a little bit of closing but then you'll see it opens he's so he
84
00:05:43.360 --> 00:05:43.480
's
85
00:05:43.480 --> 00:05:47.880
a little bit higher up than those first two were who were more in the 10 to 20
86
00:05:47.880 --> 00:05:51.600
handicap range this is a scratch golfer so he's closing it a little bit early
87
00:05:51.600 --> 00:05:57.520
but nowhere near as early as the three tour pros. So now if we're comparing all
88
00:05:57.520 --> 00:06:00.920
three of those amateurs you can see that they are starting to close the club
89
00:06:00.920 --> 00:06:01.080
face
90
00:06:01.080 --> 00:06:06.240
around the same time and space you can pause this to look for any of the
91
00:06:06.240 --> 00:06:10.160
little nuances and variances but I just want you to see kind of the overall
92
00:06:10.160 --> 00:06:15.240
pattern where most golfers tend to not close the club face early enough or
93
00:06:15.240 --> 00:06:19.800
aggressively enough to get into the same impact positions that the tour pros
94
00:06:19.800 --> 00:06:25.200
get into. And lastly this is all six of the graphs that you got to see so that
95
00:06:25.200 --> 00:06:30.000
you can compare you got the three tour pros up top and you can see the club
96
00:06:30.000 --> 00:06:34.320
position and then we've got the three amateurs on the bottom and you can also
97
00:06:34.320 --> 00:06:37.920
see the club positions you can see in general the pros are going to close it
98
00:06:37.920 --> 00:06:44.120
earlier and faster and more aggressively where the amateurs are going to close
99
00:06:44.120 --> 00:06:49.320
it later and then they have to close it very rapidly during the release as
100
00:06:49.320 --> 00:06:50.000
opposed
101
00:06:50.000 --> 00:06:54.400
to closing it a little bit earlier during transition. There's always variations
102
00:06:54.400 --> 00:06:59.920
and there's some pros who close it later some pros who close it earlier but
103
00:06:59.920 --> 00:07:04.960
in general the earliest amateurs are still usually later than the latest
104
00:07:04.960 --> 00:07:08.840
tour pros. So if you're struggling with getting into the impact position
105
00:07:08.840 --> 00:07:09.480
hopefully
106
00:07:09.480 --> 00:07:14.600
this helps you understand what has to happen with the club and then maybe it
107
00:07:14.600 --> 00:07:18.280
will make a little bit more sense why we're asking you to do some of the body
108
00:07:18.280 --> 00:07:23.120
movements during the transition and release some of the arm and club movements
109
00:07:23.120 --> 00:07:29.560
to help make this club face rotating or rotation actually create the ideal
110
00:07:29.560 --> 00:07:33.620
impact positions that tour pros tend to demonstrate with their stock tour swing
111
00:07:33.620 --> 00:07:33.760
.
1
00:00:00.000 --> 00:00:04.980
This video is explaining axial velocity so you'll see that I'm a big
2
00:00:04.980 --> 00:00:09.060
proponent of the motorcycle move and kind of getting the face to close. So in
3
00:00:09.060 --> 00:00:13.680
this video we're going to take a look at the 3D graphs that demonstrate axial
4
00:00:13.680 --> 00:00:19.840
velocity. So axial velocity is looking at how fast the club is rotating kind of
5
00:00:19.840 --> 00:00:25.200
like so. When it opens you'll see the line go negative and when it closes you
6
00:00:25.200 --> 00:00:25.320
'll
7
00:00:25.320 --> 00:00:29.400
see the line go positive. So the club will be like this and then naturally in
8
00:00:29.400 --> 00:00:32.120
the backswing I'll have a little bit of opening you'll see it go negative and
9
00:00:32.120 --> 00:00:36.280
then you'll see very different patterns for how the club closes during the
10
00:00:36.280 --> 00:00:41.280
downswing. One of the trends that you will see with tour pros is that they tend
11
00:00:41.280 --> 00:00:47.080
to close it faster earlier which is why I'm a big fan of this motorcycle

19
00:01:18.360 --> 00:01:22.350

00:01:22.350 --> 00:01:22.560
where

00:01:22.560 --> 00:01:26.600
the ball got hit in the middle. For the same reason I like to have this kind of
22
00:01:26.600 --> 00:01:31.320
smooth gradual closing of the club face the entire downswing instead of having
23
00:01:31.320 --> 00:01:37.040
it stay open for most of it and then close down to the bottom. So as you're
24
00:01:37.040 --> 00:01:40.680
looking through the graphs try to imagine how the swing would look but the
25
00:01:40.680 --> 00:01:40.920
graphs
26
00:01:40.920 --> 00:01:44.520
are going to show the actual rate of how fast that club face is closing during
27
00:01:44.520 --> 00:01:50.600
the golf swing. Okay so now we have an example of an axial velocity graph so
28
00:01:50.600 --> 00:01:55.980
the position I have right here is where they are in space at this green line.
29
00:01:55.980 --> 00:01:56.160
So
30
00:01:56.160 --> 00:02:00.560
roughly around when they start really pouring on the motorcycle movement. This
31
00:02:00.560 --> 00:02:05.320

00:02:10.480 --> 00:02:14.200
horizontal black line the faster it's moving so if it's negative it down way
34
00:02:14.200 --> 00:02:17.720
down here it will be rotating open quickly and the higher up it is the
35
00:02:17.720 --> 00:02:22.800
faster it's closing. So basically what you see is not a lot of rotation during
36
00:02:22.800 --> 00:02:26.640
the takeaway pretty much one piece little openings in closing during the
37
00:02:26.640 --> 00:02:31.960
backswing but mostly opening and then you'll see right around here before the
38
00:02:31.960 --> 00:02:35.720
top of the swing before the club changes the direction he's going to start
39
00:02:35.720 --> 00:02:36.520
closing
40
00:02:36.520 --> 00:02:39.840
the club face closes it more rapidly and then right about here it really takes
41
00:02:39.840 --> 00:02:44.000
off and he starts closing the face so that's right around this point in time
42
00:02:44.000 --> 00:02:48.840
in space is when that point in time on the graph happens to occur. It'll make
43
00:02:48.840 --> 00:02:52.160
more sense or it'll be easier to visualize when we take a look at a few
44
00:02:52.160 --> 00:02:57.600
others both pros and amateurs. Okay so here's another pro you'll see he has a
45
00:02:57.600 --> 00:03:02.240
little bit more of the opening during the backswing and during early
46
00:03:02.240 --> 00:03:06.600
transition but you'll see right around here he starts closing it and then right
47
00:03:06.600 --> 00:03:12.160
about where I have it in time and space so well well up here soon after he
48
00:03:12.160 --> 00:03:16.800
started the the downswing sequence he's now gonna start ramping up you'll see a
49
00:03:16.800 --> 00:03:22.720
bigger difference when we get to comparing the three amateurs. Okay here's one
50
00:03:22.720 --> 00:03:22.920
more
51
00:03:22.920 --> 00:03:27.680
pro you can see fairly flat during takeaway opening during the backswing
52
00:03:27.680 --> 00:03:34.900
starts closing there's in order to kind of hinge the wrists in transition you
53
00:03:34.900 --> 00:03:34.960
'll
54
00:03:34.960 --> 00:03:39.560
see typically a little bit of this dip and then right around this point in time
55
00:03:39.560 --> 00:03:43.560
somewhere here you can see that's well above where most of you may be thinking
56
00:03:43.560 --> 00:03:47.200
about closing the club face this is when he's actually starting to rotate the
57
00:03:47.200 --> 00:03:51.640
club face closed now remember if you start closing the club face early and it
58
00:03:51.640 --> 00:03:55.640
causes the ball to hook it means that there's other things going on and you
59
00:03:55.640 --> 00:04:01.280
holding the club face open is kind of a contribution to your overall pattern so
60
00:04:01.280 --> 00:04:05.200
now we've got all three pros on screen you can kind of take a look you can
61
00:04:05.200 --> 00:04:09.190
pause the video and look for some of the details but you can see in general
62
00:04:09.190 --> 00:04:09.640
that
63
00:04:09.640 --> 00:04:14.120
they are starting to close the club face while the club is still well up in in
64
00:04:14.120 --> 00:04:21.520
the air or just after they've started to transition. Now this is the first of
65
00:04:21.520 --> 00:04:26.440
the three amateurs so you'll see a slightly different pattern not too
66
00:04:26.440 --> 00:04:28.880
dissimilar in the backswing maybe a little bit more opening during the
67
00:04:28.880 --> 00:04:32.960
takeaway but then you'll see this flat line through transition where
68
00:04:32.960 --> 00:04:36.880
basically there's no rotation of the club and then you'll actually see it open
69
00:04:36.880 --> 00:04:41.960
well into the downswing you'll see he's now down to about belly button height
70
00:04:41.960 --> 00:04:45.440
where the others were up at kind of eye height or shoulder height or however
71
00:04:45.440 --> 00:04:45.560
you
72
00:04:45.560 --> 00:04:50.600
want to look at it and he still has not started to close yet this is right
73
00:04:50.600 --> 00:04:53.800
about when he's going to start closing the club face so you'll see that he
74
00:04:53.800 --> 00:04:58.040
doesn't have nearly as much time to rotate the club face closed so he's gonna
75
00:04:58.040 --> 00:05:02.840
have to do it very quickly in order to get it in the same orientation. Here's
76
00:05:02.840 --> 00:05:07.600
another amateur so we can see opening and then that same little flat line
77
00:05:07.600 --> 00:05:11.600
during transition you can see it's not until well down here that he starts to
78
00:05:11.600 --> 00:05:15.840
close the club face so this is a common pattern that we're gonna see with a lot
79
00:05:15.840 --> 00:05:20.840
of amateurs who struggle with their transition and release this is kind of
80
00:05:20.840 --> 00:05:25.360
one of those graphs that kind of tells a lot of the story as to why their swing
81
00:05:25.360 --> 00:05:31.160
may be being built the way that it is. And then lastly this is a scratch golfer
82
00:05:31.160 --> 00:05:38.160
a very very good very accomplished amateur so you'll see a still a kind of
83
00:05:38.160 --> 00:05:43.360
flat line with a little bit of closing but then you'll see it opens he's so he
84
00:05:43.360 --> 00:05:43.480
's
85
00:05:43.480 --> 00:05:47.880
a little bit higher up than those first two were who were more in the 10 to 20
86
00:05:47.880 --> 00:05:51.600
handicap range this is a scratch golfer so he's closing it a little bit early
87
00:05:51.600 --> 00:05:57.520
but nowhere near as early as the three tour pros. So now if we're comparing all
88
00:05:57.520 --> 00:06:00.920
three of those amateurs you can see that they are starting to close the club
89
00:06:00.920 --> 00:06:01.080
face
90
00:06:01.080 --> 00:06:06.240
around the same time and space you can pause this to look for any of the
91
00:06:06.240 --> 00:06:10.160
little nuances and variances but I just want you to see kind of the overall
92
00:06:10.160 --> 00:06:15.240
pattern where most golfers tend to not close the club face early enough or
93
00:06:15.240 --> 00:06:19.800
aggressively enough to get into the same impact positions that the tour pros
94
00:06:19.800 --> 00:06:25.200
get into. And lastly this is all six of the graphs that you got to see so that
95
00:06:25.200 --> 00:06:30.000
you can compare you got the three tour pros up top and you can see the club
96
00:06:30.000 --> 00:06:34.320
position and then we've got the three amateurs on the bottom and you can also
97
00:06:34.320 --> 00:06:37.920
see the club positions you can see in general the pros are going to close it
98
00:06:37.920 --> 00:06:44.120
earlier and faster and more aggressively where the amateurs are going to close
99
00:06:44.120 --> 00:06:49.320
it later and then they have to close it very rapidly during the release as
100
00:06:49.320 --> 00:06:50.000
opposed
101
00:06:50.000 --> 00:06:54.400
to closing it a little bit earlier during transition. There's always variations
102
00:06:54.400 --> 00:06:59.920
and there's some pros who close it later some pros who close it earlier but
103
00:06:59.920 --> 00:07:04.960
in general the earliest amateurs are still usually later than the latest
104
00:07:04.960 --> 00:07:08.840
tour pros. So if you're struggling with getting into the impact position
105
00:07:08.840 --> 00:07:09.480
hopefully
106
00:07:09.480 --> 00:07:14.600
this helps you understand what has to happen with the club and then maybe it
107
00:07:14.600 --> 00:07:18.280
will make a little bit more sense why we're asking you to do some of the body
108
00:07:18.280 --> 00:07:23.120
movements during the transition and release some of the arm and club movements
109
00:07:23.120 --> 00:07:29.560
to help make this club face rotating or rotation actually create the ideal
110
00:07:29.560 --> 00:07:33.620
impact positions that tour pros tend to demonstrate with their stock tour swing
111
00:07:33.620 --> 00:07:33.760
