So with the squat narrow versus wide, your ability to go narrow is your ability to have that relative motion in the pelvis. With the upper body list, it would be, I guess, more relative motion in the rib cage or just that ability to expand the rib cage A to P. to get into those narrower spaces? Is that the same representation?

OK, so hang on.

Relative motion.

Okay.

That is correct, sir. This is absolutely correct. Welcome to the complexity of working with an athlete, because the way that they do things is not average. We've talked about this. It's like you can't treat them like average. Their norm is their norm, not the norm. And so I don't know. If I have a baseball pitcher that's six foot seven, and I have another guy that is six foot two and one is biased more towards a wide and one is biased more towards a narrow. Should I expect them to produce the output of pitching the same way? You can't do it. You just can't do it. You have to appreciate the fact that their mechanics will be idiosyncratic. Therefore, their ranges of motion will be idiosyncratic. So how much retroversion do you want? I don't know what allows them to do what they do for a living, kind of a thing, right? And so that's, so we measure, we monitor, we make small measurable changes that we determine would be in a favorable direction under the circumstance, but there's no guarantee you'll be right. So that's what we have to monitor.

But again, you understand what I'm saying, right? As far as where you need to go with this, right?

Okay, so static stretching addresses one end of the yield and overcome relationship. If I take a rubber band and I pull it back, that's a yield. If I pull it back and release it very quickly, it snaps back, so that's the overcome. But understanding how connective tissue behavior works is that when you yield, if you hold the static stretch long enough, you squeeze the water out from the outside, and then it slowly comes back into shape like a Stretch Armstrong toy. You know what I'm talking about? And it slowly comes back into shape as the water that got squeezed out goes back into the tissues. So until that water goes back in, you have this yielded tissue that won't snap back, so it will not overcome fast enough. Therefore, the power output that's associated with movement is the stretch and release element of connective tissues.

Right, so again, yeah, it's the front to back stuff that's probably gonna create more of the orientation. It doesn't mean you can't get there. That's the thing I want you to recognize is like you're not stuck out in this wide space forever, but you gotta gradually bring them in. Cause if you do it too fast, you get pain.

You kind of have to start in segments. I have to get the right orientation here. So I get the right orientation at the elbow. I have to make sure it's approximately at the right orientation. So like I said, it's just that sequential kind of a representation.

So this brings up some very interesting point. They measured a thousand people, mostly Caucasians, and a third of them were Asian people.

Good morning. Happy Friday. I have neuro-coffee in hand and it is perfect.

Flat thoracic spine and a narrow versus a wide. Can you tell me a little bit about that or how it came about?

Awesome.

Okay. Happy birthday coming up.

Does that clarify that to a sufficient degree for you?

Yes, they did. They didn't. They were afraid that they were going to hurt your feelings, so they wanted you because they were like, 'Come on, Johnny, you can do it. Give it the old college try. You can be anything you want as long as you want it bad enough.' And that's the biggest lie in the world. You can be great at something that you were meant to be great at. That's the answer. So what you have to do as a human being is you have to discover that. How do you do that? Well, you expose yourself to a bunch of things and then eventually you're going to find something that you like. And the reason that you like it is probably because you're good at it. So some people turn into Tony Hawk and become professional skateboarders, and some people turn into Brandon Woodruff who can throw 98 miles an hour at a moment's notice. All of my athletes are like really old people because I don't pay attention to like the current sports and stuff; I think back to like the 70s and 80s. You know, who Tom Brady is arguably one of the better quarterbacks around. He's been around longer; the longer you stay, the more records you get to play or get to break. But it's like no, he was predetermined to be good at certain things. Tom Brady is never going to be a great running quarterback; I mean, you can't be a great running quarterback when you're in a 5-2-40. But take the cognitive side of it; I think he's probably got that nailed down. He can throw well enough. Joe Montana was very similar; he was not known for having a cannon of a throwing arm, but he was a great quarterback because talk about somebody that's cool under pressure and a great thinker in stressful situations. So you compensate for certain elements of it; that's what makes certain people really, really good. You can take somebody that has the greatest physical tools. Let's look at Cam Newton; does anybody have better physical tools? Probably not. Is he the greatest quarterback that's ever lived? No, he has moments of greatness. But you have to look at what you bring to the table, what are your strengths, and then you just have to understand those and apply them to whatever environment that we're working in. And we're saying, 'Okay, your chances are you're going to be able to do this, and then we'll try to move you towards something that you're really, really good at.'

OK.

Right. Because the threshold of what you would consider that point at which someone is moving into their patterns that would feed their powerlifting performance is sometimes difficult to find, right? Because you could get someone a split squat and you can put a dumbbell in the contralateral hand to try to restore like internal rotation or something like that. And one person, it could work totally well to see a relative load, but others, it could be a total disaster. Yes.

Okay. Yep.

Yeah.

Internal rotation in sprinting. Let's talk about top speed because that's where the highest velocity is. The ground contact time at the highest possible level of performance is about 0.08 seconds. That's how much time you have to apply force. A sprinter actually lands on their foot at or near maximum propulsion, which is the maximum amount of internal rotation into the ground. It's not the maximum amount of joint rotation that we typically associate with internal rotation. It is a downward force. That's why you hear me talk about internal rotation being down. That's why you see every sprinter on the planet with an anteriorly oriented pelvis. That is a performance-related adaptation or a gift from the gods, if you will. It allows them to create this downforce because it's the force into the ground that is associated with top speed. That's where internal rotation occurs. But because you're on the ground, there's literally the most minimal amount of movement available at that point. If you've ever seen my little diagram of the cones where the cones go from external rotation to internal rotation, that one point right in the dead center middle is where the sprinter is going to be demonstrating internal rotation. So it is the briefest moment in time possible because if I extend that, I take away speed. Internal rotation stops time, which sounds like a wild and crazy kind of thought process, but that's the reality. It slows things down because anytime you're producing force, that's where you have ground contact. That's where you are pushing against a baseball. That's where you are lifting a heavy weight. If we looked at this from like a max effort squat or max effort bench press, that's internal rotation all the way through the press. Is it fast? Never. When we're talking about things that are high velocity, I cannot produce velocity with high tension at the same time. I can produce the force that will allow me to demonstrate the velocity, but I have to have expansion to allow the velocity to be demonstrated. When you see the legs cycling through space during sprinting, that's not internal rotation. It's external rotation, absolutely. Again, we're not talking about maximums or anything like that; it's within a range. For me to cycle my legs as fast as I do, they're flying through the air; there's no ground contact. So what am I pushing against? Nothing. That's an external rotation bias that allows me to move quickly. A baseball pitcher that is throwing a baseball at 95 miles per hour has this one tiny little moment during his lead foot ground contact time where he produces the maximum force into the ground and then everything else is extra rotation where he demonstrates the velocity. If I extend the duration at which I am applying force, it's really slow. It's like all you gotta do is look at the representation of max effort strength training versus something that's really, really high velocity. Now you kind of know why there's this very weak relationship between high speed activities and high force producing activities. Making someone gym stronger does not necessarily translate to higher velocity activity.

I appreciate the university core. I'll catch you on the next I fast university.

I had a couple of questions. First, I wanted to talk about the diaphragm. And I was wondering, we've talked about how there's asymmetry in the body. Does the diaphragm go straight down? Or does it go down unevenly? Or does it go down at an angle, following the curve of the body?

Yeah, that's great.

It's the only space available. That's brilliant.

I don't know, I guess I'm placing more expectation that they're putting expectation on me. And they're identifying something as progress. And if they're not seeing that or I'm not actually communicating that I don't actually know what I'm doing fully well.

When is the next Bill and Ted coming out? Do you know?

It's like a gradient that comes from the.

I was saying that I can't get IR relative motion.

I'm using the, think about what you gain on the left and lose on the left as you go up.
