If I hold my arm here or I hold my arm here, the arms are not in the same position. So the degree of relative motion changes.

SPEAKER_04 0:08–0:24
I have a very basic question regarding the lengthening of the right side in a narrow. So too many questions that you answered about people with the rectus strategy.
rectus strategynarrow stanceright side lengthening
SPEAKER_05 0:25–1:19
And they are narrow with the flat turn, so they fall. They go first forward to the left and then they go to the right. They turn to the right and then they find themselves forward on the right. So they create a rectus strategy and they pull. It's like you were talking with Jim Laird before that the force is down. So they have a strong IR. And you always answer that you first have to lengthen the right side. So what would be some effective exercise that you would give for some? So you always say that you have to create the late ER in that side.

Yes, ma'am.
SPEAKER_05 1:21–1:31
And so how would you do it? Just how would you emulate this position of you just how's your martial arts.

SPEAKER_02 1:34–1:40
I'm not practicing anymore. OK, but what was your what was your art? What did you what did you study?
SPEAKER_05 1:40–1:42
OK, awesome.
SPEAKER_02 1:43–2:27
All right, so. You're going to remember this, right? Okay, you got to stand up for me. Okay, because I want you to do this. Let's not overcomplicate. You know how to do your horse stance? Yeah, horse stance. Awesome. Yeah, get your horse stance. Okay, and get ready to punch. Get ready to punch. No, we're going to go the other way. We're going to go the other way. Hold it out there. Hold it out there. Awesome. Now, shift your weight from right to left. So the left knee is now bent and the right leg is now straighter, correct? Right. You've just lengthened the right side into an ER position.

SPEAKER_05 2:31–2:46
So would you give them such a shape, such a position and then tell them to breathe because the issue is, like you said for Jill, the air is not holding them. There is no air in the right.

SPEAKER_02 2:46–3:13
Okay, so how many exercises can you come up with that are in that shape? Like change the positions, change the angles. Literally, take your end position, take your end position. Okay? Can you appreciate that you're pushing the right side into the left side and then the left side is holding you back?

SPEAKER_05 3:14–3:14
Right.
SPEAKER_02 3:15–3:56
There you go. So how many exercises can we come up with that utilize this relative position? That's all you got to do. So is there more weight on your left side than your right side? Yes. Absolutely. There has to be because I have to unweight the right side to make it go up, don't I? Uh huh. Okay. Is your right leg straight and pushing you from right to left and posterior to anterior? Yes, it's the late E.R. actually in the right. That is exactly right. That's what you're trying to achieve when you're trying to bring somebody up from that lowered center of gravity, for sure. Don't you have to E.R.?

Does the humerus rotate as well?

SPEAKER_02 3:58–4:34
You did. You did. You did. Isn't this internal rotation? Hold your arm up. Turn your thorax away. Turn your thorax to the left. As you preach, what way did you go? Because the talk is there. Don't stare at your hand. Don't stare at your hand. Look at the mechanics, approximately. I see, I see. So this is, although it is twisted in the thorax, it's not twisted in that direction. It's twisting in the other direction. You're looking at your hand.

SPEAKER_05 4:36–4:39
I see, because the form now is the other now.

SPEAKER_02 4:40–5:08
You twisted this more than this. The relative position here is ER to here. I see. If I turn away, I increase the ER here, no matter what you think you're doing here. Because again, people stare at their hands and think the wrist doesn't move separately from the forearm. Yes, it does. The forearm doesn't move separately from the humerus. Yes, it does. The humerus doesn't move separately from the scapula. Yes, it does. So where is the relative motion?

SPEAKER_05 5:11–5:24
So wouldn't it be better to also ER the wrist? To create the full range of motion. What position do you want the scapula to be in?
scapula positioningexternal rotation (ER)shoulder mechanics
SPEAKER_02 5:26–5:39
You want it to be ER. No. Where's the relative motion? So you just made your hand, elbow, and humerus one piece. You understand that? Where's the relative motion? Between the scapula and the shoulder. Between the humerus and the scapula right now, correct? What representation do I want on the scapula? Do I want an ER at scapula or an IR at scapula?

SPEAKER_05 5:41–5:41
Right.
SPEAKER_02 5:42–5:57
You understand that? Where's the relative motion? Between the scapula and the shoulder. Between the humerus and the scapula right now? What position do I want on the scapula? Do I want an ER at scapula or an IR at scapula?

SPEAKER_05 5:58–6:02
In lady R, you want the scapula to be ER.
scapular orientationexternal rotationshoulder mechanics
SPEAKER_02 6:02–6:21
Okay. So I have to consider where the degree of relative motion would be. Okay, so it's going to depend on where you are in space as to what orientation of the humerus you're going to use. You're away from midline. You're away.

SPEAKER_05 6:21–6:25
Can you appreciate that in the hills away from the?

SPEAKER_02 6:25–6:28
It's away from midline because your sternum is turning to the left.
scapular positioningsternal rotationshoulder mechanics
SPEAKER_05 6:29–6:30
Yeah.
SPEAKER_02 6:34–6:44
Yeah, it's so difficult to, I mean, conceptually. If I hold my arm here, or I hold my arm here, the arm's not in the same position. So the degree of relative motion changes. So if I bring my arm this way, if I want to create an ER representation of the scapula, I'm going to drive it from my hand all the way into the scapula because then the scapula is going to follow. If I'm away from here, I'm going to turn it this way because I'm going to get the relative motion of the scapula to turn in the opposite direction. You're using a left foot forward split squat offset load right. You're moving into the cut. So you're descending into the split squat.

SPEAKER_05 6:44–6:46
Right?
SPEAKER_02 6:46–7:13
So if I bring my arm this way, if I want to create an ER representation of the scapula, I'm going to drive it from my hand all the way into the scapula because then the scapula is going to follow. If I'm away from here, I'm going to turn it this way because I'm going to get the relative motion of the scapula to turn in the opposite direction. You're using a left foot forward split squat offset load right. You're moving into the cut. So you're descending into the split squat. Right. Yes. So you're going to encourage, you're going to encourage the accumulation of internal rotation.

SPEAKER_01 7:13–7:13
Yeah.
SPEAKER_02 7:14–7:31
Yes. So you're going to encourage the accumulation of internal rotation. Good morning. Happy Thursday. I have neural coffee in hand and it is.
