Good morning. Happy Thursday. I have neurocopy in hand and it is perfect.

Okay, so let's start like crazy simple. Let's go day one. Simple rule: you move in the direction of expansion. So the pelvis is moving in the direction of expansion, right? There you go, step one.

Huh?

That?

ER is up and IR is down.

And if you have too much posterior compression, you won't even get that elbow up. That elbow will be pointing behind.

Forced production.

It may be that the forces are too high. So the downward force is too high. For instance, one of the simplest solutions would be to do a reverse band squat. You get the rubber bands above them, so you reduce the downward force and then see what happens there.

Sure. Yes.

So your thought process is correct. They may not want to do that. You may want to move them back towards early and then create the orientation at the knee because I've got internal rotation coming up from the ground in that situation. To prevent the ER from being superimposed.

OK.

Okay.

Have you noticed that he can't turn his head all the way in one direction?

Now you're thinking. Okay, so if I want to ER that representation there, I need eccentric orientation across that space, because what you want is like, I'm going to fix the humerus. I want that to happen. Which means that that's DR expansion. See the medial border moving posterior. There's my delay, right? But to do that, subscapularis has to be able to eccentrically orient. And if it doesn't, you ain't going to get ER. What you're going to get is that, which is going to look like it's pointing towards ER. Okay. All right. So number one, you definitely need your posterior expansion. So I'm on point with that, but you got to eccentrically orient subscapularis. Now we got to start thinking about where else do you need to get that same representation?

Again, it's like we have to look at this from the circumstances. Can they even achieve the optimal position first and then train force production in that position? It's not a matter of like, oh, we have to correct something. This might be an element of training that needs to be addressed first and foremost. Can they capture the position?

Gotcha, all right.

There it is, that's your answer, right there, 1,000%, okay? So this is the difference between rolling from prone or supine to prone and prone to supine, okay? Prone to supine requires that I drive the spine towards internal rotation. You see it? Yeah, so now let's take your neurologically insulted individual, okay? We've got a change in constraints. But the rule doesn't change. So I start you in a position where I know you can be successful. So maybe I put you directly inside line, and then I'm teaching you to roll towards the mat from in the posterior direction. Do you see it? Okay. You can drive upper extremity that way. You can drive lower extremity that way. And so you're starting to teach them how to reorient the spine in a low gravity situation first, capture the position, then teach them how to produce force. So same rules that we were just talking with Zach with an ACL. It's like, okay, do they even have the position where they can produce force first? So when you talk about strengthening things, it's like, yeah, force production is important, but can they even acquire the position? Do I want to try to teach them to produce force in an ER representation? Probably not going to work too well, right? Exactly. You start there, you can apply manual resistance into that rotation. So this is PNF. So PNF will be a wonderful way for you to drive that stuff because it's based on helical orientations. So you apply the resistance in the helical orientation. So you can leave them with resistance or you can have them push into resistance. And so then you start to develop the force production within a narrow range and then you just expand that range to the best of whatever capabilities they have available based on the remaining constraints. You drive head, you drive thorax, you drive pelvis.

So let me ask you this, Temus. If we were talking dead guy anatomy, what would that tibialis anterior do based on all the textbooks?

That's the fact. So those are the fastest people. Assuming that that moment of time that stops where you have maximum IR, assuming that that is extremely high force, yes. And the shortest possible time. So if we looked at a sprinters foot contact, okay, that is a maximum force into the ground. And at world class levels, I think it's 0.08 to 0.11 seconds on the ground, which is incredibly brief.

Like a squat.

Yeah, could you give a quick example of what you just described?

They moved to the right first.

It's like, what are they? What do they present with? Right? There are elements of complexity here that we just don't know. We don't know exactly where they are. We don't know how changeable they are. We don't know to what degree we need to make a change to get the influence that we want. So this becomes the experiment, but as long as you're following the principles, that's where you're safest in doing your work.

It's not there. It doesn't exist. This is a byproduct of increased force production. As I gain the capacity to compress more—whether through hypertrophy or the coordination of compression—I will give up expansion. At some point in time, the best of the best will do this. There might be exceptions to the rule where somebody actually has great relative motions and is the strongest person in the world, but that would be pretty rare. They just don't have the space anymore to allow them to capture the ER positions. But they don't care—they just want to lift heavy things.

Yeah. Cause people get carried away with the concept of ascension and descent. And they think that that's the match. The match is the muscle behavior. Concentric and eccentric is the match.

All right. Well, that's your reporter. All right, man. I'll see you.

little bit of abduction.

Yeah, I know. It's not even possible for me.

You'll be just. Yeah, that's not good. Um, so what is it useful then to try?

Yes.
