00:00:00.719 --> 00:00:02.240
in this golf smart insight we're going

00:00:02.240 --> 00:00:04.560
to answer a question about the risks

00:00:04.560 --> 00:00:06.879
from michael on facebook so michael was

00:00:06.879 --> 00:00:07.600
asking

00:00:07.600 --> 00:00:10.080
a very technical question and if you're

00:00:10.080 --> 00:00:11.440
a beginning golfer

00:00:11.440 --> 00:00:13.679
please turn this off and just go look at

00:00:13.679 --> 00:00:15.040
some of the other drills because

00:00:15.040 --> 00:00:17.119
this is going to be some some high level

00:00:17.119 --> 00:00:18.960
theory stuff

00:00:18.960 --> 00:00:21.520
but michael was asking on 3d graphs

00:00:21.520 --> 00:00:23.199
you'll frequently see

00:00:23.199 --> 00:00:25.920
that the trail wrist is going to flex

00:00:25.920 --> 00:00:26.240
through

00:00:26.240 --> 00:00:29.039
impact at a rate faster than the left

00:00:29.039 --> 00:00:30.400
wrist is going to extend

00:00:30.400 --> 00:00:33.280
now whether that's one to one so they're

00:00:33.280 --> 00:00:34.079
going the same

00:00:34.079 --> 00:00:35.840
whether it's one to four which is about

00:00:35.840 --> 00:00:37.120
the most that i've ever seen where this

00:00:37.120 --> 00:00:39.840
is going four times faster than this one

00:00:39.840 --> 00:00:42.640
that's uh that's kind of up to a little

00:00:42.640 --> 00:00:44.480
bit of different swing styles

00:00:44.480 --> 00:00:47.039
but generally you're going to see the

00:00:47.039 --> 00:00:48.320
right wrist going at least

00:00:48.320 --> 00:00:50.239
twice as fast as the left wrist is going

00:00:50.239 --> 00:00:51.600
to be extending

00:00:51.600 --> 00:00:54.719
so the question is why well i don't have

00:00:54.719 --> 00:00:55.280
the

00:00:55.280 --> 00:00:56.960
the answer but i have some things that

00:00:56.960 --> 00:00:58.640
make sense to me so i'll present them to

00:00:58.640 --> 00:01:00.719
you here in this video

00:01:00.719 --> 00:01:03.920
so anytime i'm looking at a movement

00:01:03.920 --> 00:01:05.760
there's primarily three things that

00:01:05.760 --> 00:01:06.720
we're going to look at we're going to

00:01:06.720 --> 00:01:07.280
look at

00:01:07.280 --> 00:01:10.640
path face and power so how does this

00:01:10.640 --> 00:01:12.479
movement help me create speed

00:01:12.479 --> 00:01:14.400
how does this movement help me control

00:01:14.400 --> 00:01:15.759
the path how does this movement

00:01:15.759 --> 00:01:18.240
affect the face to the path now because

00:01:18.240 --> 00:01:19.600
this is happening

00:01:19.600 --> 00:01:22.400
literally you know inches before impact

00:01:22.400 --> 00:01:23.360
it's probably

00:01:23.360 --> 00:01:25.920
not going to have a drastic effect on

00:01:25.920 --> 00:01:27.360
the face and path

00:01:27.360 --> 00:01:29.520
so let's go at power because that's

00:01:29.520 --> 00:01:31.200
where i think that

00:01:31.200 --> 00:01:32.799
this difference is really going to show

00:01:32.799 --> 00:01:35.600
up more so from the power perspective

00:01:35.600 --> 00:01:37.280
there's two things that we need to

00:01:37.280 --> 00:01:38.880
address one

00:01:38.880 --> 00:01:40.880
how the heck are we gonna create speed

00:01:40.880 --> 00:01:43.119
two how are we gonna control that speed

00:01:43.119 --> 00:01:45.119
and what i mean by that is how are we

00:01:45.119 --> 00:01:46.479
gonna safely

00:01:46.479 --> 00:01:49.520
stabilize because in most sports there

00:01:49.520 --> 00:01:50.000
is a

00:01:50.000 --> 00:01:52.079
follow through for a reason it helps you

00:01:52.079 --> 00:01:53.680
can handle the

00:01:53.680 --> 00:01:55.280
the speed and the force that you have

00:01:55.280 --> 00:01:57.280
created with the object whether it's my

00:01:57.280 --> 00:01:59.040
arm and i'm throwing a ball

00:01:59.040 --> 00:02:02.079
or it's a bat and i'm swinging it how am

00:02:02.079 --> 00:02:02.880
i going to

00:02:02.880 --> 00:02:05.600
safely handle all this force that's

00:02:05.600 --> 00:02:07.119
coming back at me from the implement

00:02:07.119 --> 00:02:08.800
that i've created

00:02:08.800 --> 00:02:13.280
so one of the studies that i love from

00:02:13.280 --> 00:02:14.959
from baseball and i learned about this

00:02:14.959 --> 00:02:16.640
in one of my czech classes

00:02:16.640 --> 00:02:19.360
was they took a baseball pitchers and

00:02:19.360 --> 00:02:20.319
they basically

00:02:20.319 --> 00:02:22.959
monitored their contribution of speed by

00:02:22.959 --> 00:02:23.760
joint

00:02:23.760 --> 00:02:26.560
and what they found was you know once

00:02:26.560 --> 00:02:27.599
you got them up let's say you were

00:02:27.599 --> 00:02:29.440
throwing 90 miles an hour there was kind

00:02:29.440 --> 00:02:29.920
of a

00:02:29.920 --> 00:02:31.599
everybody had their own pattern of how

00:02:31.599 --> 00:02:32.959
much speed they were creating from their

00:02:32.959 --> 00:02:34.160
legs from their trunk

00:02:34.160 --> 00:02:35.519
and from their shoulder and from their

00:02:35.519 --> 00:02:38.000
arms well as they got tired so as they

00:02:38.000 --> 00:02:40.319
did through 50 60 pitches

00:02:40.319 --> 00:02:42.480
the interesting thing was the velocity

00:02:42.480 --> 00:02:44.080
of what they were throwing the ball

00:02:44.080 --> 00:02:46.239
pretty much maintained the same the ones

00:02:46.239 --> 00:02:48.879
who were more prone to injury

00:02:48.879 --> 00:02:51.040
basically changed their pattern of how

00:02:51.040 --> 00:02:52.560
they were creating the speed

00:02:52.560 --> 00:02:54.800
so instead of having let's say 25 coming

00:02:54.800 --> 00:02:56.800
from the legs it was now only 20

00:02:56.800 --> 00:02:58.319
and they were getting much more from the

00:02:58.319 --> 00:03:00.400
arm those players would be much more

00:03:00.400 --> 00:03:01.440
likely to suffer

00:03:01.440 --> 00:03:03.920
you know some type of elbow injury when

00:03:03.920 --> 00:03:05.519
they would get tired

00:03:05.519 --> 00:03:08.080
so the thing the takeaway that i took

00:03:08.080 --> 00:03:08.640
from this

00:03:08.640 --> 00:03:11.680
particular study is that we have

00:03:11.680 --> 00:03:14.480
kind of this governor in us that allows

00:03:14.480 --> 00:03:15.920
us to only move something

00:03:15.920 --> 00:03:18.159
so fast that we can control it it's kind

00:03:18.159 --> 00:03:19.599
of like when you're

00:03:19.599 --> 00:03:22.400
sprinting and you come to a downhill and

00:03:22.400 --> 00:03:23.840
your legs just start moving so

00:03:23.840 --> 00:03:25.519
fast that you can't handle it you have

00:03:25.519 --> 00:03:27.280
to kind of throttle yourself back

00:03:27.280 --> 00:03:29.200
so even though you're physically capable

00:03:29.200 --> 00:03:30.560
of going faster

00:03:30.560 --> 00:03:32.560
because you don't have the stability in

00:03:32.560 --> 00:03:34.480
place to handle it

00:03:34.480 --> 00:03:36.080
it's going to be a problem in your brain

00:03:36.080 --> 00:03:37.920
recognize that and pulls you back

00:03:37.920 --> 00:03:39.760
so how does that apply to this movement

00:03:39.760 --> 00:03:41.840
in the golf swing well

00:03:41.840 --> 00:03:44.879
i think the important question is you've

00:03:44.879 --> 00:03:46.159
created

00:03:46.159 --> 00:03:49.360
100 pounds 150 pounds of force

00:03:49.360 --> 00:03:51.200
by getting this light object to swing

00:03:51.200 --> 00:03:53.519
100 you know 110 miles an hour or

00:03:53.519 --> 00:03:54.480
whatever

00:03:54.480 --> 00:03:57.360
well you have to handle that force in

00:03:57.360 --> 00:03:58.640
one way or another

00:03:58.640 --> 00:04:01.120
so i always ask people what muscle

00:04:01.120 --> 00:04:02.000
pathway

00:04:02.000 --> 00:04:03.760
would you like to have handling a

00:04:03.760 --> 00:04:05.120
hundred hundred fifty

00:04:05.120 --> 00:04:07.760
pound force going down away from you

00:04:07.760 --> 00:04:08.959
like so

00:04:08.959 --> 00:04:10.720
and if you look at it from that

00:04:10.720 --> 00:04:12.799
perspective i think it'll start to make

00:04:12.799 --> 00:04:13.200
sense

00:04:13.200 --> 00:04:16.320
why the left wrist is going to be

00:04:16.320 --> 00:04:19.359
not flexing very very quickly and the

00:04:19.359 --> 00:04:20.560
reason is

00:04:20.560 --> 00:04:23.280
the right wrist when it flexes and the

00:04:23.280 --> 00:04:24.639
tricep extended

00:04:24.639 --> 00:04:26.720
extends this is all helping to create

00:04:26.720 --> 00:04:29.040
speed but as we've seen from a lot of

00:04:29.040 --> 00:04:30.000
golfers

00:04:30.000 --> 00:04:32.080
the the right hand is going to be

00:04:32.080 --> 00:04:34.000
relatively loose and in some golfers

00:04:34.000 --> 00:04:35.680
it's even coming off the club

00:04:35.680 --> 00:04:37.759
the right hand is in a very poor

00:04:37.759 --> 00:04:39.919
position for stabilizing that speed

00:04:39.919 --> 00:04:42.400
it's kind of more like baseball um where

00:04:42.400 --> 00:04:44.000
you'll typically see

00:04:44.000 --> 00:04:46.400
after contact with a lot of hitters that

00:04:46.400 --> 00:04:47.280
lead hand

00:04:47.280 --> 00:04:49.120
or sorry that trail hand come off the

00:04:49.120 --> 00:04:51.280
club because it's in a poor position to

00:04:51.280 --> 00:04:52.560
stabilize that force

00:04:52.560 --> 00:04:54.240
where the lead hand is actually in a

00:04:54.240 --> 00:04:55.840
pretty good position to be able to

00:04:55.840 --> 00:04:57.680
stabilize it

00:04:57.680 --> 00:05:00.240
so i think what the lead arm is going to

00:05:00.240 --> 00:05:01.199
be doing

00:05:01.199 --> 00:05:04.240
from about there

00:05:04.240 --> 00:05:06.240
through till the end of your swing is

00:05:06.240 --> 00:05:08.320
helping to stabilize this force that

00:05:08.320 --> 00:05:09.280
we've created

00:05:09.280 --> 00:05:11.759
as opposed to contribute much more force

00:05:11.759 --> 00:05:13.120
i think that's going to be coming more

00:05:13.120 --> 00:05:14.560
from the trail side based on the

00:05:14.560 --> 00:05:16.639
movements that the trail side is doing

00:05:16.639 --> 00:05:18.320
so if we're looking at how we're going

00:05:18.320 --> 00:05:19.919
to stabilize force with the lead

00:05:19.919 --> 00:05:21.600
arm there's a couple different pathways

00:05:21.600 --> 00:05:23.680
to get it from my hand to my shoulder

00:05:23.680 --> 00:05:27.919
right if i was to supinate like so

00:05:27.919 --> 00:05:29.759
or if i was to ulnar deviate that's

00:05:29.759 --> 00:05:31.280
going to activate muscles down

00:05:31.280 --> 00:05:33.600
this inside edge of my arm which is

00:05:33.600 --> 00:05:34.400
going to help

00:05:34.400 --> 00:05:36.800
support kind of my external rotators and

00:05:36.800 --> 00:05:37.759
my shoulder

00:05:37.759 --> 00:05:40.000
so this movement kind of all works well

00:05:40.000 --> 00:05:40.880
together

00:05:40.880 --> 00:05:42.560
and that movement is going to involve

00:05:42.560 --> 00:05:44.720
some big muscles like my shoulder blade

00:05:44.720 --> 00:05:45.600
depressors

00:05:45.600 --> 00:05:47.919
such as my lat and my mid trap so when

00:05:47.919 --> 00:05:49.440
this weight gets moving

00:05:49.440 --> 00:05:51.039
very very quickly i'm going to have this

00:05:51.039 --> 00:05:53.039
shoulder kind of in a good supported

00:05:53.039 --> 00:05:54.960
position so that it can support it

00:05:54.960 --> 00:05:57.039
if i was to have my shoulders kind of

00:05:57.039 --> 00:05:58.880
shrugged and my elbows out like so

00:05:58.880 --> 00:06:01.360
and i got this weight moving 150 pounds

00:06:01.360 --> 00:06:01.919
it would be

00:06:01.919 --> 00:06:03.520
the same thing as if i was trying to do

00:06:03.520 --> 00:06:08.800
a shoulder shrug like this of 150 pounds

00:06:08.800 --> 00:06:12.080
if i personally was to do that you know

00:06:12.080 --> 00:06:14.479
80 90 times a day which is roughly a

00:06:14.479 --> 00:06:15.600
round of golf

00:06:15.600 --> 00:06:17.440
i would probably end up with shoulder

00:06:17.440 --> 00:06:18.639
and neck dysfunctions

00:06:18.639 --> 00:06:20.400
not that i don't already have those but

00:06:20.400 --> 00:06:23.120
it would be drastically worse

00:06:23.120 --> 00:06:26.400
so if i was to flex this wrist somewhat

00:06:26.400 --> 00:06:27.520
aggressively

00:06:27.520 --> 00:06:29.600
it will activate the muscles and you can

00:06:29.600 --> 00:06:31.039
see them kind of activate there

00:06:31.039 --> 00:06:32.720
it will activate the muscles more on the

00:06:32.720 --> 00:06:34.319
top side of my forearm which will

00:06:34.319 --> 00:06:36.479
connect more with my anterior delt and

00:06:36.479 --> 00:06:37.440
upper trap

00:06:37.440 --> 00:06:40.319
so doing this very very rapidly you'll

00:06:40.319 --> 00:06:42.639
see that my arm actually wants to shrug

00:06:42.639 --> 00:06:45.440
up as opposed to when i go like this my

00:06:45.440 --> 00:06:47.120
arm actually wants to kind of

00:06:47.120 --> 00:06:51.039
shrug down or screw into place so

00:06:51.039 --> 00:06:53.680
if i'm going to extend it wouldn't work

00:06:53.680 --> 00:06:54.479
well with

00:06:54.479 --> 00:06:55.919
the rest of my body as far as

00:06:55.919 --> 00:06:58.880
destabilizing or stabilizing the force

00:06:58.880 --> 00:07:00.880
because the rest of my body my arm is

00:07:00.880 --> 00:07:03.360
going to be extending through that phase

00:07:03.360 --> 00:07:06.479
even if that left wrist is going to be

00:07:06.479 --> 00:07:09.039
extending a little bit as well and it's

00:07:09.039 --> 00:07:09.919
not really

00:07:09.919 --> 00:07:11.360
that it's going to be extending it's

00:07:11.360 --> 00:07:13.680
coming from a flex position towards

00:07:13.680 --> 00:07:14.960
neutral

00:07:14.960 --> 00:07:16.400
it doesn't actually get into its

00:07:16.400 --> 00:07:18.960
extended position until

00:07:18.960 --> 00:07:20.319
after i've made contact with the golf

00:07:20.319 --> 00:07:22.080
ball for the most part

00:07:22.080 --> 00:07:24.240
so i think that it's more of a product

00:07:24.240 --> 00:07:26.080
of how i'm going to stabilize

00:07:26.080 --> 00:07:27.680
and i'm sure that this will lead to more

00:07:27.680 --> 00:07:29.280
questions which will be great

00:07:29.280 --> 00:07:32.560
but if we look at kind of how rotation

00:07:32.560 --> 00:07:35.520
happens in the spine and the ribcage

00:07:35.520 --> 00:07:38.800
where basically if i flex

00:07:38.800 --> 00:07:40.639
one side of the body and i extend the

00:07:40.639 --> 00:07:41.840
other or if i

00:07:41.840 --> 00:07:43.840
push away with one side and i pull away

00:07:43.840 --> 00:07:46.160
with the other that creates rotation

00:07:46.160 --> 00:07:48.720
it would start to make sense as to why

00:07:48.720 --> 00:07:50.479
this right side may be going down and

00:07:50.479 --> 00:07:51.919
through and this left side would be

00:07:51.919 --> 00:07:53.120
going back and up

00:07:53.120 --> 00:07:54.720
and if the left side is going back and

00:07:54.720 --> 00:07:56.560
up it doesn't make sense for me to

00:07:56.560 --> 00:07:57.759
extend this wrist

00:07:57.759 --> 00:08:01.360
very aggressively it may not affect

00:08:01.360 --> 00:08:03.919
contact but it would definitely affect

00:08:03.919 --> 00:08:05.680
how i would stabilize the force in the

00:08:05.680 --> 00:08:07.199
follow-through and i think that would be

00:08:07.199 --> 00:08:10.560
the bigger issue
