I have posted up here is a cross section of the thorax through the scapula so we can see where the humerus is. And what I want to do is I want to talk you through how we manipulate internal and external rotation by the position of the scapula. So if you look at this first diagram, what we have is a representation of what we would consider some sort of normal average kind of a thing where the scapula would rest 30 degrees off the imaginary frontal plane. And so that gives us a starting position. The starting position is kind of important to understand because as we start to move through space time, we're going to see differences in concentric and eccentric orientation. So if I have an anterior compression, what I'm going to end up with is I'm going to get expansion on the posterior side. And what this is going to do is going to change the angle of the scapula relative to the imaginary frontal plane. So now if I have a 60-degree angle, I pick up concentric orientation on the backside of that shoulder. So if you want to pick on a muscle, you could say your principanatus picks up concentric orientation. And then I have a limitation of internal rotation. So that's how the anterior compression works. And so if I want to expand anteriorly, what I have to do is I have to reverse this process. So what I'm going to do now is I'm going to pick a shoulder girdle position. I'm going to pick an activity that produces concentric orientation of the muscles between the scapula. So I'm going to compress that dorsal rostrum area. I'm going to pin the medial border of that scapula against the rib cage. And what that's going to do, it's going to drive the expansion forward. So now what I have is I have a change in that angle of the scapula. So it's not a much flatter angle relative to the frontal, the imaginary frontal plane. And so what that does is it gives me eccentric orientation on the backside of that shoulder and now I pick up the internal rotation. So that's basically the mechanism that we're talking about. So that's how reaching activities tend to work is they create this dorsal-rostral compression. They get the anterior expansion. I get my pump handle back and then bingo-bango, I get my internal rotation.

It's a bias, it's structure, it's not gonna change, but if you use it with my archetypes, it will lead you towards better interventions and hopefully more successes. You're still gonna have failures. The idea is to reduce the probabilities of what is possible and to help you be more successful.

I can't just say that, oh, if you put your weight on this side, this is gonna happen. What we're doing is we're inducing a situation that allows us the potential to access these. And so one of the things that we have to consider is that when the goal is to restore movement or enhance movement, the load can actually be interference. And so this means that there might be situations where we need to manipulate gravity. So one of the ways that we can manipulate gravity is to use pulling motions from above. So it's like a cable chop activity where we're pulling weight down is actually a reduction in the demands of gravity. In other cases, we have to take people all the way down to the floor where we might have to put them in sideline and then progress them to half kneeling and then finally up to a split stance because they just don't know how to manage gravity as well. So there's a lot of potential interference here but the thing that we want to understand is that the goal is to induce the potential or to make things easier or to facilitate the ability to make these turns with the loading through the extremities. So when we talk about The strategy, the most common errors that we're gonna see as I've already mentioned a little bit is too much load. So we're talking about gravity, we're talking about external loads. So anything that can influence this via load would be like a medicine ball that's too heavy. Weighted baseballs that are too heavy will extend the propulsive phase and actually reduce our velocity up to a certain point. Weighted golf clubs, can also become interference and so that's why we would move you towards activities that would reduce that load. Too much velocity too soon so a lot of people can't control these end ranges at higher velocities and so what they end up doing is they end up expanding They're max propulsive strategies, so they use too much concentric orientation. They actually reduce the velocity in an attempt to control it. And again, that becomes interference to rotation. So we get this orientation where the entire system is turning as a unit versus getting this relative motion through the pelvis and through the thorax that we want to actually produce this nice, clean, smooth, and efficient rotation. too much excursion. So some people just don't have the joint excursion available to them under certain circumstances. And so what we might have to do is start with a very narrow stance to try to induce some of these yielding strategies. And then we can slowly expand their stance to access these broader motions. And then we can start to apply that through their excursion. So for instance, if I was taking a golfer that was having trouble with follow through. I might need to start him in a very, very short staggered stance before we can actually induce a normal width stance for him because he just can't control the velocity. He can't access the ranges of motion.

Expansion AP to the pelvis would do what to the ischium? So you're thinking like the pubis being pushed forward.

So that will typically give you the like an anterior orientation of the pelvis?

The volume won't be nearly as high, but again, we need both aspects. We have to look at this from this coordinate of tissue adaptation concept, and then we have to look at this from the output of the nervous system itself. We can still use our training RMS that will help guide us in regards to our recovery, which again, remains valuable. But now we have some guiding principles here. And then your supplementary exercises are all so important. They contribute some volume, so they're going to influence recovery. They're going to influence your ability to move and adapt. So those are considerations, but less or so when we're trying to bring up a lift, such as a box squat or a deadlift. So hopefully that gives you a little bit of thought process anyway. And if you have any questions about program, please send them to askbillhartmanagingmail.com. Have a great Friday and a great weekend. I'll see you in a minute.

He can get past 90.

So if I put a load on you and you have to breathe a certain way, the costal and the crus diaphragms behave differently. The shape is non-uniform. People say, well, of course the left side's lower than the right side and blah, blah, blah, blah. I'm talking about looking at this from a side view. You can see the front and the back part of the diaphragm. The back parts of the costal diaphragm are attached to the spine and are also more anterior. They behave differently. There's a very specific shape that would take place that would be associated with the position of the ribs. When we talk about wide and narrow zones of apposition, it's like, well, if the diaphragm's attached to the ribs, that diaphragm has to be in a different shape. Anatomically speaking, we've got a lot of problems in the way that we describe things that create so much more confusion. It's not helpful. Looking at things as if they were different, but that's, you know, if we're basing our net anatomy off of guys that did the first dissections like about 2300 years ago. 300 BC, I think were the first recorded dissections. They got to name the stuff because they were first. If we're basing, in all seriousness, we're basing our anatomical understanding off of guys that did dissections 2300 years ago with absolutely no foundation of understanding. It's like, oh, well, we've always done it this way. Now we're back to Michelle's question about what would you change about school? First of all, clean the slate. Let's rename everything. Because even though we were terrible at naming stuff, I think we could be better at it now than we were 2,300 years ago.

What do you mean by that? Just cough for me for a second.

Hope you had a productive week. Have a great weekend. I'll see you next week.

Okay. So, if you sit on the hard chair long enough, your butt starts to hurt, right? Yes.

What are some of the things you, I guess, test or look for to decide that?

I don't think it changes me from one-on-one perspective, but I think it changes things maybe from a team perspective in a lot of ways. Because I was thinking about it yesterday, it's like just because you have access to certain equipment doesn't mean it's a need or a want, like part of the why, right? Because people are going to run back into the weight room and be like, I need to get back in the squat rack. Well, it's like justify it, right? Like justify it for this person.

So it would be eccentric elongation of muscular tissue that would allow that position. Be just management of like guts.

Yeah, and some of our retests were simply: 'All right, now do something that usually bothers you, whether it's touching your toes or lifting something off the floor, sitting—like do something that usually bothers you to see if we've made the change that we need to make.' So yeah, she stood up from that, felt no pain, 100% better, did some of the stuff. Now my plan for her is to see her once a week for four weeks, going to continue to dial it in, but it's going to be really good as the coordination. She's going to see her personal trainer twice a week. It's going to be ongoing and definite effort. We're going to be able to coordinate that care. I'll check in with her today to see how she's feeling as she's going through stuff. But I think as now the personal trainer has specific exercises she can use in a warmup or super set with like an elevated deadlift she's been doing. You know, she now has principles of that. I told the trainer: 'Just focus on these things with the exercises that you're prescribing and you should be okay to move forward.'

Car garage.

Yeah, everything seems all fine and wonderful until it doesn't seem all fine and wonderful, right? If you don't pay attention, you don't see it coming because all you're seeing is the good stuff and you're not monitoring for the things that you've taken away. Let me offer you this, the fact that you and I can speak the same language because we're part robot is that we didn't see it coming until it came. Right. And it will happen again because your identity is no different from what it was before. But the thing that you have on your side now is you are much more rational in regards to what the possibilities are from a negative consequence standpoint. And I think that's really powerful. But that's this conversation. This is you and I. And I'm listening to myself as I say this too because I run into the same problem. It's like, oh, I'm taking a risk here. It's a calculated risk. And so I'm going to limit my exposure because there's certain things that I want to be able to do too. I try to maintain those the best that I can, but I also try to be a little bit more rational in regards to how much I am applying from a load standpoint or speed standpoint because you just have to now because you have a hip there that doesn't adapt and the stuff around the hip that is securing it does adapt. You can have negative adaptations to the structure that's holding the implant in place. And that's what causes the changes in the hip over time that result in the requirement of having to have that stuff redone. And that's what you don't want to do. Because you and I got this stuff young because of our ability to out-train our body's ability to repair itself. And so we don't want to do that again.

So a metal ISA would be more prone to expansion, right?

It's a representation of the strategy and then the response of the structure to that strategy. Is that what you want to do?

A true increase in thoracic flexion would be a sternum in a down pump handle position, right?

No, that's not what I said. It's the early hip ER. You are in front of the box.

I get that. But I'm thinking that the posterior is a bigger space, first of all, and also that the gas.

Yeah, especially in the world of higher specialization. So like a baseball pitcher, because they're so focused on one aspect of performance.

Yeah, so you spend more time during the conscious hours trying to resolve the limited number of options. So you're trying to restore options so that when they do go to sleep, they're not limited in options.

If we were going to ask Mike, that is worse. It was a sprinter product.

OK, so here's this week's note card. I should write this story up. My high school English teacher just died recently, and she's the one that taught me how to use note cards. This was back when you had to use note cards because we didn't have these really cool apps. You see my little file system back there? I categorize everything in note cards. You've been to a library? At least once in your life, you've been to a library. Do you know how they categorize books by number?

This arc was the wrong word.

Yeah, you'll see the width of your impulse.

Yeah, yeah, yeah. OK. So now you know you've got DR compression that's also going to be interference. So if he doesn't have, so that's his release, if you will, his release position. So he's going to have a lot of anterior posterior compression. So you got to get AP, right? Because the anterior expansion is going to provide you space for him to create the internal rotation. So he doesn't have that either.

So why do you use a purely static activity in the first place? Like you're literally creating the shape that they need at a moment in time because that's where the interference is. They're not securing that position. They're either trying to go around it too fast or they're trying to go through it too slow. It's like, I got to create this position first and then I can start to expand this window where they can actually utilize that representation. I want all of my activities to be dynamic. Right. I want fluidity. It's like, why do they, I can't do it. I'm not graceful at all. But my ballerina always has like the, you know, like she moves through space in this incredibly graceful way. But no, it's like, this is how you decide. It's like, oh, I can go into, I can do a cross-connect step up. Because they have demonstrated the ability to control the starting position, capture the position that I want, and then move back out of it so they can transition through the sequence or propulsion. I got something that can't do that. I know where they are. I know where they can't go. And I got to set up that spot where I got to teach them the position first. I got to teach them how to shape change, hold that position, and then I can move them out of it.
