Okay, have you watched sports on TV?

Well, they do meet because we have to consider this conservation event. I have a force that's pushing up as the ball is pushing down, and wherever they meet, our momentum has to be conserved. So I have two forces that are meeting. It's like, where do you want this meeting to take place? And do you want me to damp it? One of the easy ways to do what I think you're asking is to do a medicine ball slam. Let's say you've got your back foot on the ramp. So you have a staggered stance with the back foot on the incline. We'll do a medicine ball slam on the diagonal in that direction with a release. We typically do a release point, but you can do them with a fake throw and distribute the yielding action that way as well.

So as you come down and you hit that heel rocker position, you're going to land in that early propulsive position. So your tibia is going to be in extreme rotation, and that's your first metatarsal head. So when that hits the ground, that's where you're going to start to superimpose internal rotation on top of the external rotation position because that's what this is. This early propulsive position is external rotation, and you land here. Okay? And then as your tibia starts to translate over, this is where you're going to start to really superimpose a lot of internal rotation. So this is your high force into the ground as you move over that foot. Here's the really cool thing: you can see this on slow-motion video. I'm trying to think of his name—there's that, oh, shoot, I wish I could remember his name. I would sound so intelligent right now. Berkeley? Maybe? Is he blonde? Yeah, he's okay. Okay. Yeah. So if you watch him in slow motion, he has a beautiful representation of this as he's throwing. You can see a video of him from the front that I would suggest you look at. What you're going to see is the foot kind of landing on the outside edge, then hitting the metatarsal rather aggressively, and then you'll see the tibia translate over. But the cool thing is you're going to see this huge wave go up through his body—literally, it looks like a wave—going up from his foot through his leg, through his torso, through his rib cage, into the arm. This is the wave that comes up from the ground; it's the force coming up from the ground through your body in a split second. And then he translates that into the ball. So what you're seeing is this maximum propulsion wave that comes up from the ground. So as soon as I apply that first pressure—the first metatarsal into the ground—the wave starts. And as you translate over it, it gets magnified and is huge; it's this big, huge wave. You'll see the curve through the spine, translating up into the shoulder, into the arm, and then into the ball. But you've got to make sure you capture that. That's the big toe side of your foot, the first metatarsal into the ground. There's also a difference between cricket and baseball: you'll see some baseball pitchers that bend their lead knee, but cricket bowlers tend to keep their lead knee straight, much like a javelin thrower. Right? Yeah. And that also creates a downward force into the ground through the knee. So again, this is what magnifies that internal rotation into the ground. So I have to have a tremendous amount of downforce to create this wave of internal rotation that goes up into the extremity. Right? Yeah. We are always superimposing this internal rotation on top of this external rotation position. So as this wave of internal rotation goes up through the body, what you'll also see right behind it is an expansion that follows. So when you're landing in this early propulsive position, what we've done is we've created a delay strategy on the lead foot to allow the throwing arm to translate ahead of that lead foot. So that's what that ER wave is—the delay that comes right behind the high force. So what you're going to see: if you're a right-handed thrower, looking at yourself from the right side as you throw, you should see the right hip starts to translate ahead of the left. You'll see what I describe as your left back pocket stays back, and your right back pocket goes forward. Then you'll see it go up into the lower back—so until the lumbar spine, you'll see that delay strategy on that side as well, as the right side is translating forward. If you don't see that delay strategy, then you have two sides that are trying to go together, and there's no differential. If there's no differential between the two sides, you have a reduction in throwing velocity because instead, you have a longer distance to travel. If I take both sides of the pelvis and try to turn the whole pelvis as a unit, I have to go around the left lower extremity instead of straight through the left lower extremity. So I want as straight a line as possible towards the direction I'm throwing to maximize velocity. So what it's going to look like in the pelvis: when I plant my left foot and capture that early propulsive strategy, the sacrum is going to be moving backwards on the ilium—that's what creates this expansion on the left side. The right side is going through that. That's where my velocity is going to be. I have to slow this side down to let this side go forward. If both sides are trying to go forward at the same time, it's no longer a straight, long line—it's a curve, because what I want is to plant here and then go straight through.

So, I guess we'll stick with this case. So, goals still include getting those connective tissues to yield and be more compliant. But then in the case of a post-op ACL, we still need to work on plyometrics at some point. Yeah. Is that completely interference at this point where she's still having pain with these other activities?

Yes, I do. Okay. So then how would this apply to let's say, the discussion around like if I flex my biceps to 90 degrees? If I flex my biceps and my elbow flexes. Thank you. If I flex my biceps and my elbow flexes.

So she looks like it's way up, am I correct? Yes.

So that's a lumbar spine that's turning towards that hip as you're turning it. When you get a magnification of like a straight leg raise, or hip flexion, that tends to be somebody that's going to be rolling away from you. And so you're not actually measuring in that imaginary sagittal plane anymore. You're measuring away from that midline, right?

All right.

Okay.

We only have a few minutes. Yes. Quick review. OK. Four small talks, nine minutes each. Nine minutes each. You make your point, you give examples, and then you make your point. So it goes point example point, four times. Little transitions in between to get you from one point to another. Patient walks in, here's the findings. Step one. Step two, here's what those findings mean. Step three, here's where we're lacking shape change to allow this movement to occur. Step four, here's an intervention that I can show you will reacquire the internal rotation of the shoulder that caused the positive test in the first place. Talk done. Any questions?

Okay, all right. So if you're going to do social media to attract parents of the kids that you want to work with, they're probably going to be older. So they're probably going to be in the 40 to 55 range, yes, right? To have a kid of that age, give or take, right? So Facebook is probably going to be a great place for you to hang out and talk to the parents. Yeah, but you also want to inspire the kids to draw attention. So they want to do cool stuff and the kids are going to go, 'mom, dad, I want to go train with Nate, okay?' Where do those kids hang out?

You ever see it come up unevenly? And they finished? Sure. Yeah. You know why they did that?

Exactly.

I guess just nonstop pressure is bad.

At every level. So you think about an athlete, and I think the athlete is the obvious one, right? Because they come in and say, well, I want to run fast, jump high, whatever. And so it's a little bit easier to identify that. But I think that if you go into the gym at any time of the day, whether it be the morning crew or the afternoon kids or the evening, even the adult people that come in, they're all coming in with purpose. So, as we have a tendency to say, if you want to get there, you've got to come here. And, Rick—yeah, big Rick—he's a mountain climber. It's like so he comes into train to be better at that. And so, it doesn't matter whether we're talking about our early morning retirees that come in. And they come in and they're coming in with purpose. They say, I need to be able to do this. I want to play with my grandkids. I want to be able to get up and down off the floor forever. I want to be able to garden. I want to be able to do whatever they want to do. And so they come in with purpose. And so while they get excited about a personal record on their trap bar deadlift, ultimately it becomes like, oh, guess what? Everything else in my life is now effortless. Yeah, and so we've been very lucky in that respect.

Think about the constraints. It's like, okay, I've got a scapula that's basically attached to the rest of the body by 17 muscles. There are a couple of weak joints, if you will, relative to you going down to the hip and the pelvis. And you go, okay, the SI ligaments are the strongest ligaments in your body. It's like not a lot of movement going on there. So you have a better shot. And again, probably a more immediately useful strategy by alleviating the pressure on the neck. But you're going to have to do it from the side, because especially a wide rib cage, if you put them on their back, and if you try to put them in a head position that would open the airway, like if you had to do CPR on a compressed wide rib cage, right? Yeah, it doesn't go well.

Right. So let's start with the spine, the spine and the second of turning to the other way. And so, the spine is in ER in the right. And so you said that ER spine is a flexion in the spine. I never said that. That's right. Yeah. Right. So what is happening if the spine is in ER? What is happening to the ilium in that side?

No. It's OK. It's not a dirty word. But let's be realistic. I don't think it says what we would think it is like the way it appears to be on real humans. So, the nerves move. I'm not denying that part. What I am having issues with is what reduces the movement of the nerve itself.

So, so yeah, so you're going to have to But again, it's a controlled representation of what you're actually driving as you're driving the right hip forward to turn them left. So it's a turn that looks like that. So when they land, you understand the starting conditions, right?

Sure, I'll go with that.

So have you thought about how, if you were to map this out in your model, have you thought about a method of sort of visual description that best accommodates that. So you're thinking like, you know, all the time.

The idea is not to make them stick there, just to let them sense what.

Okay. But it's not. So she's doing like one of those deals, right? It looks like that. Yes. Okay. So, so that's not a normal motion. That's, that's, that's a broken constraint, if you will, right? She's, she's messed with the constraint. Okay. But that doesn't change. That doesn't change the orientation. So what needs to be able to move? So yet a femur, that was oriented into ER and then you got, you recaptured some space, allowed it to turn inward. Makes sense. Yes. So I gotta get that to move, don't I? Okay. You see the, you see the, you see the similarity. It's like this joint won't move, but it's, it's not moving because this isn't changing its shape. You change the shape and the femur favorable, cool, but I didn't change this. So you got like a hip that should allow the knee to move, but I got a foot that says, nope, not going to let it move.

So where is the IR hitting the ground? So the arch is very low to the ground, correct? Where would you perceive the IR to be resting on the ground? Everywhere. So do you have a rear foot adaptation or does it appear to be more of a midfoot adaptation or do you have a bunion?

That's my trigger. This is what I've been teaching people is basically almost like to feel like this back here is kind of getting relaxed.

Yeah.

Dr. Pat Davidson's mentorship. So he's applying all the concepts.

So here's what happens. Your ground contact time is longer in acceleration than it is at peak velocity. Understood?

OK, so let's just nip this in the bud. An isometric means same length. It's never the same length. The position doesn't change much, but the length changes as you execute the activity. So it's a misnomer and it's a misrepresentation. That's why I don't like it.

I feel like my light bulb moments have gotten subdued because I realized there's just going to be another point of being compressed and in pain of thinking about something. So.
