Shoulder External Rotator Isolated Activation

Shoulder External Rotator Isolated Activation is a stretching and strength training exercise that focuses on activating and strengthening the external rotator muscles of the shoulder. This exercise requires the use of an exercise band to activate the targeted muscles which are responsible for externally rotating and stabilizing the shoulder joint. This exercise is ideal for athletes of all sports who want to improve their shoulder strength and stability as well as injury prevention. It is also a great way to help relieve shoulder tension and stiffness from everyday activities

00:00:0500:00:07
Institute. In this video we're doing our
00:00:0700:00:10
variation of a very common exercise,
00:00:1000:00:13
which is activation for the external
00:00:1300:00:14
rotators of the shoulder which have a
00:00:1400:00:16
propensity to become underactive in
00:00:1600:00:18
those with shoulder or upper body
00:00:1800:00:20
dysfunction. I'm going to have my friend,
00:00:2000:00:21
Brian, come out. He's going to help me
00:00:2100:00:24
demonstrate. Now, the common exercise we
00:00:2400:00:27
like to use, because it's bilateral, it
00:00:2700:00:29
doesn't take a lot of equipment, and it
00:00:2900:00:32
just happens to be very convenient is
00:00:3200:00:35
chest out, thumbs out. So, if Brian
00:00:3500:00:39
takes this band here and he just
00:00:3900:00:42
does one of these things, you guys can
00:00:4200:00:45
kind of see that's bilateral
00:00:4500:00:47
external rotation. Now on top of this, we
00:00:4700:00:49
just have to figure out how we
00:00:4900:00:51
optimize this. At the Brookbush
00:00:5100:00:52
Institute, the first thing we think about
00:00:5200:00:54
when we do our activation exercises is
00:00:5400:00:57
what are our overactive synergists? So,
00:00:5700:00:59
anytime we have an inhibited group of
00:00:5900:01:01
muscles, in this case, the external
00:01:0100:01:02
rotators being the infraspinatus and
00:01:0200:01:04
teres minor, we have muscles that are
00:01:0400:01:07
going to try to take over that job. In
00:01:0700:01:10
the case of the external rotators, the
00:01:1000:01:13
supraspinatus and posterior delt start
00:01:1300:01:14
trying to do the job of the
00:01:1400:01:16
infraspinatus and teres minor. We have
00:01:1600:01:19
to start thinking, how do I reciprocally
00:01:1900:01:23
inhibit my overactive synergists? Well,
00:01:2300:01:24
the supraspinatus is easy. My
00:01:2400:01:27
supraspinatus is an abductor. So what am
00:01:2700:01:28
I going to do to reciprocally
00:01:2800:01:31
inhibit? Adduct a little bit. I'm just
00:01:3100:01:33
going to squeeze the elbows into the
00:01:3300:01:37
ribcage. As far as my posterior delt, my
00:01:3700:01:39
posterior delt does extension. So to
00:01:3900:01:41
reciprocally inhibit, I'm going to do a
00:01:4100:01:44
little bit of flexion. So if he, rather
00:01:4400:01:48
than gets back here, hugging back on the
00:01:4800:01:49
side of his rib cage, goes to the front
00:01:4900:01:51
of his rib cage and just hugs the front,
00:01:5100:01:55
kind of like where this little angle
00:01:5500:01:56
is right here, or the little corner of
00:01:5600:01:59
your ribs stick out. If he keeps his
00:01:5900:02:01
elbows touching there, we should be good
00:02:0100:02:07
for reciprocally inhibiting his supraspinatus and posterior delt. And I think what
00:02:0700:02:09
Brian's about to find out is as soon as
00:02:0900:02:11
he goes back to try to externally rotate,
00:02:1100:02:13
this isn't going to feel as easy as it
00:02:1300:02:15
did the first time you did it. So, go
00:02:1500:02:16
ahead and give that a
00:02:1600:02:23
shot. Deep breath. A little harder? Yeah.
00:02:2300:02:25
Yeah, you guys will find that people
00:02:2500:02:27
can do all sorts of weight when they
00:02:2700:02:29
bring their arms back, because
00:02:2900:02:31
they're using those big posterior delts
00:02:3100:02:33
to try to get a lot of force in
00:02:3300:02:35
external rotation, and then all of a
00:02:3500:02:36
sudden you reciprocally inhibit those
00:02:3600:02:39
overactive synergists, and they don't
00:02:3900:02:40
have nearly as much strength as they
00:02:4000:02:43
used to. And, generally speaking, they'll
00:02:4300:02:44
start feeling it where they're supposed
00:02:4400:02:47
to. Remember, your infraspinatus and teres
00:02:4700:02:48
minor are kind of on the back of your
00:02:4800:02:51
scapula here. I can actually feel,
00:02:5100:02:53
palpating is infraspinatus, I can
00:02:5300:02:57
feel it just go "szoof" puff up.
00:02:5700:02:59
Yeah, it does. It actually makes that
00:02:5900:03:02
sound. He's going to have jacked infraspinatus.
00:03:0200:03:05
You think you can get 12 to 20
00:03:0500:03:07
repetitions? That was at least 10 right there.
00:03:0700:03:09
That was 10? Good, because I want you a
00:03:0900:03:13
little slower on the tempo. So, remember,
00:03:1300:03:15
guys, your tempo for these activation
00:03:1500:03:19
exercises are either 4-2-2, being a 4
00:03:1900:03:22
second eccentric. Or, if you
00:03:2200:03:23
wanted to concentrate on range of motion,
00:03:2300:03:27
you can go 2, 4 second hold, 2, 3, 4
00:03:2700:03:30
and then a 2 second eccentric. Now,
00:03:3000:03:32
we're going to even take this up another
00:03:3200:03:36
notch, because this dysfunction of the
00:03:3600:03:39
shoulder and the upper body is often
00:03:3900:03:42
very related to cervical dysfunction as
00:03:4200:03:44
well. We have a couple muscles of
00:03:4400:03:46
the scapula, being our upper trap and our
00:03:4600:03:47
levator scapulae that connect our
00:03:4700:03:50
cervical spine and our upper body
00:03:5000:03:52
dysfunction real quick. I'm going to go
00:03:5200:03:54
ahead and place Brian up against this
00:03:5400:03:59
wall here. And now on top of all of the
00:03:5900:04:01
stuff that we just did- his
00:04:0100:04:03
shoulders being a little bit into
00:04:0300:04:05
flexion, keeping his scapula down and back,
00:04:0500:04:09
good, and he's hugging his rib cage, I can now
00:04:0900:04:13
have him head back, chin tucked, putting his
00:04:1300:04:16
external occipital protuberance back
00:04:1600:04:19
against this pad, helping to stimulate his
00:04:1900:04:23
deep cervical flexors while I have him
00:04:2300:04:25
do this.
00:04:2600:04:27
Oh, man, we're getting good
00:04:2700:04:30
bang for our buck on this exercise now.
00:04:3000:04:32
We've reciprocally inhibited our
00:04:3200:04:34
overactive synergists, we're activating
00:04:3400:04:36
our external rotators, which we wanted to,
00:04:3600:04:38
and we're even getting a little bit of
00:04:3800:04:42
deep cervical flexor activation, keeping
00:04:4200:04:48
his head back against that wall.
00:04:4800:04:50
Is it getting hard? You've only
00:04:5000:04:53
done about 25 reps so far. Guys, generally
00:04:5300:04:55
we'd only do 12 to 20 reps. Now, the last
00:04:5500:04:57
thing Brian is going to show you is
00:04:5700:04:59
we're going to do this one arm at a time.
00:04:5900:05:01
Occasionally, you do have somebody who
00:05:0100:05:04
has unilateral dysfunction, right, they're
00:05:0400:05:06
only dysfunctional on one side. It is
00:05:0600:05:09
important that if you have dysfunction
00:05:0900:05:12
on one side that you correct dysfunction
00:05:1200:05:14
on that side alone. Something I find
00:05:1400:05:18
myself repeating often lately is you
00:05:1800:05:22
can't fix asymmetrical dysfunction with
00:05:2200:05:25
a symmetrical intervention. So, if he only
00:05:2500:05:27
had dysfunction on his right side, and I
00:05:2700:05:30
only want him to do right-sided external
00:05:3000:05:33
rotator activation, all I'm going to do
00:05:3300:05:38
is wrap my band around some solid
00:05:3800:05:43
object and follow all those same cues. This
00:05:4300:05:45
one is where the towel comes in handy.
00:05:4500:05:46
Some of you guys have probably seen
00:05:4600:05:48
external rotator activation where they
00:05:4800:05:51
put a towel under here. Why he has that
00:05:5100:05:54
towel is if I have him adduct and
00:05:5400:05:56
just hold the towel- you don't have to
00:05:5600:05:58
squeeze the towel- just hold the
00:05:5800:06:00
towel on the front of his rib cage, it'll
00:06:0000:06:02
help keep his shoulder girdle where
00:06:0200:06:04
it's supposed to be. It'll help me keep
00:06:0400:06:07
reciprocally inhibiting those overactive
00:06:0700:06:10
synergists, once again, being his supraspinatus
00:06:1000:06:13
and posterior delt.
00:06:1300:06:15
For some reason, the chest out, thumbs out
00:06:1500:06:17
tends to keep us where we're supposed to
00:06:1700:06:18
be, and then we go to one arm and it's a
00:06:1800:06:23
little easy to get flailing around. How
00:06:2300:06:29
does that feel? Good. Good, like terrible.
00:06:2900:06:32
Yes, like it hurts so good. You guys know
00:06:3200:06:35
the feeling. Now, with all exercises, one
00:06:3500:06:37
thing I want to remind you guys of is
00:06:3700:06:39
this isn't the end. Although this is
00:06:3900:06:41
convenient, that chest out, thumbs out
00:06:4100:06:42
exercise, especially against the wall
00:06:4200:06:44
makes a wonderful warm-up, you can do it
00:06:4400:06:47
with a huge group of people in a
00:06:4700:06:50
classroom setting or a team setting, you
00:06:5000:06:53
do have to progress exercise. There is
00:06:5300:06:54
going to be a point in time when this
00:06:5400:06:57
exercise is going to be too easy for
00:06:5700:07:01
Brian. We need more than just up the
00:07:0100:07:02
weight of the band, up the weight of the
00:07:0200:07:04
band, up the weight of the band. Remember,
00:07:0400:07:06
the goal with activation exercises isn't
00:07:0600:07:08
hypertrophy. I'm not trying to get him
00:07:0800:07:10
the most jacked infraspinatus that
00:07:1000:07:12
anybody's ever seen. That actually sounds
00:07:1200:07:15
a little ridiculous just saying it.
00:07:1500:07:17
There is another video after this
00:07:1700:07:20
called External Rotator Activation
00:07:2000:07:23
Progressions where we show several
00:07:2300:07:25
progressions to this exercise. You need
00:07:2500:07:29
to check it out. Start here. Let me know
00:07:2900:07:32
what your outcomes are. As I've said in
00:07:3200:07:35
all the videos up to this point, if I
00:07:3500:07:37
have Brian doing this, it's because I
00:07:3700:07:40
found something that was indicative of
00:07:4000:07:43
external rotator inhibition in his
00:07:4300:07:45
assessment, whether that's arms fall on
00:07:4500:07:47
the overhead squat or a lack of external
00:07:4700:07:51
rotator flexibility. So, if I did my
00:07:5100:07:52
goniometry, maybe he lacks a
00:07:5200:07:55
little bit of external rotation. Or,
00:07:5500:07:57
if I was going to directly test this, an
00:07:5700:08:01
external rotator manual muscle test. Do
00:08:0100:08:03
your assessments. Do your intervention.
00:08:0300:08:06
Reassess. Let me know what your outcomes
00:08:0600:08:07
are. If you have any questions, please
00:08:0700:08:09
feel free to leave them at the bottom of
00:08:0900:08:11
this video.
