Yeah, I'm leading with the left knee. I just want to know is it safe or is it OK to let the left cable pull me forward on the left. But then I'm just putting my left leg towards the late.

I was having difficulty figuring out when I see people with those big posterior lumbar compressions and that big curve of the spine. When you look at that visually, you might think they're in an anteriorly oriented position, but they're narrow. Compared to the swayback position, which appears to go in the opposite direction but isn't real. They just push slightly in a different manner, still pushing forward but differently.

As you gain access to relative motion. So you think about that. So I have to be able to concentrically and eccentrically orient muscles in a co-ordinative manner. Eccentrically oriented muscle doesn't have tension on it. So it feels effortless. So my range of motion, my excursion of range of motion improves. And so that's what you're recognizing. So you're absolutely right. That is like one of those things that you would start to recognize. Okay. But it's also helpful for you to understand how hard an exercise is for your client. Right. So you, so you, you, you, you sort of threw yourself on your swords. Yeah. I've been screwed on my clients, not necessarily, not necessarily because you don't have their perception of how hard the activity is to begin with.

Oh, man, I don't even know if I tend to forget things as soon as I say them now because I'm 55 years old. So if they had a normal breath in, the sacral base would be moving posteriorly, and the spine would move in opposition under those circumstances. That would reduce the inward curve, the internal rotation of the spine, or the extension lordosis. But they don't have normal breathing because of the structural bias. That's why they start using compensatory strategies. That's why there's a center of gravity problem. That's why they have to start to superimpose superficial musculature on top of the axial skeleton to hold position over their center of gravity so they don't fall. So step one, understand the so-called normal mechanics—the average mechanics of what breathing in and breathing out looks like—creating the structural bias on top of that and saying, okay, they're not going to be very good at this. So a wide pelvic structure isn't going to be very good at counter-nutating like a narrow one would, and vice versa. Then you say, okay, well, if they can't breathe normally, so I have a guy that can't inhale like everybody else does, how's he going to do it? Oh, he's going to cheat. If he cheats, where's the expansion going to be? Now he's lost his balance. And now we're back to Ivan's question at the beginning. It's like, oh, he's falling backwards. Let's give him a little shove from behind. Okay.

Yeah.

You just, we can cut to the chase like dorsal rostral area.

No.

Right.

Yeah. Yeah. All you're doing is just, again, pure progression. But again, you don't have to change the magnitude. But you're going to change the amplitude of the movement. And you're going to change the rate at which they are performing it.

Hey, good morning, Bill. What's up? So one of the things that I've been wrestling with lately at work is I'm on the neuro team. So the majority of my caseload is neuro. So I've been trying to find a way to make the model more cohesive within my treating. So one of the things that I noticed is that a lot of my caseload will be seated most of the time throughout the day, and they have a lot of, what appears to be, eccentric orientation along, say from T7 down to the sacrum. It's very rounded. So if I look at their measures, they appear to have a lot of ER and very, very little IR is what it appears to be. So I'm thinking of incorporating back strengthening, like things that they could do at home, like prone positioning to try to improve their upright posture, understanding because they seem to be very rounded. And so that's one of the things that I've been wrestling with. And then finding ways to progress them against gravity, since they don't have that much time standing up against gravity. Do you do mat work with them? I do, yeah. I've done rolling with them. I try to have them do it at home, especially if they have a caregiver getting them up from the ground. Give me, so is this like just a combination of stuff from strokes to TBI to...

Um, range middle.

Yes.

Okay. So is that a delay? Yes. Yes.

So again, you're on the right track. However, I would advise being more patient and capturing more external rotation before attempting to recapture internal rotation. Ensure your representation at the pelvis is appropriate because I suspect you're overshooting your capabilities, which puts you back in a late representation. It's a classic pattern of trying too hard. The seven components of force variability—is that what you're asking me?

Okay. Let's talk about posterior lower though. Can we do that? Yes, because you mentioned it. All right. So here's what's going to happen. We have to consider space-time, right? I start pushing here, I'm pushing this forward, right. This pushes back and then I keep going forward, right. My center of gravity is going to go forward under these circumstances. So eventually I'll see the pelvis moving through space in that direction over the femur. So I'll fix the femur to the ground through the foot as a representation, right. So now I have this musculature down here. The farther forward that I go, this will be able to pick up concentric orientation, right. So that and then that creates compression in the posterior lower aspect. That's how you start to pick that up. So we're looking at, say, a wide ISA representation, right. Because typically under those circumstances, I'll have a nutated sacrum, which will give me eccentric orientation of that posterior lower aspect. But if I keep pushing things forward and forward and forward, again, I start to pick up concentric orientation here, and then I start to bend this sacrum up underneath. That's one of my favorite representations to understand how you pick up this stuff, right. Because all it is, is I'm moving the two ends of a muscle closer together. So it picks up concentration. That's a compressive strategy to slowly increase the amount of compression that you can apply in that area because the center of gravity is always going to go forward. You can't go backwards. We all know there's no backwards, right. It just doesn't happen. And so you're always going to go in that direction.

Yeah, I've watched that call.

So, after the world. Yes.

Okay.

OK, cool. So how about real quick, how does that play out when you've got early and late stance representation, regardless of the archetype that have bunions?

So hang on. Are you teaching it well? Are you doing it like the people that don't care?

Position, position, breathing, shape, right? When we talk about shape, right? Because we can actually identify those things. But again, it's an understanding. It's having an understanding of what those representations may be. Also, humble yourself a little bit and recognize the fact that you'll probably be wrong sometimes. And that's just real. I just don't hurt people, right? It's always a safe experiment. You're not putting people at risk under those circumstances. If you're unsure, you don't do it.

Really? And you really think it was you? Okay. Maybe. Maybe. You know. Everything right. You could do everything right.

Awesome. What would be my natural reaction if there's a load in front of me that's pulling me down? Move backwards. I'm going to move backwards, right? So right away, I put the goblet here. This is why we use heels elevated goblet squat because it's anterior to my center of gravity, which means that I'm going to move away from that weight to maintain my center of gravity, right? So right away, I'm starting to create that yielding action. Right, it's an early propulsive representation. Look where my arm is relative to my body as well. Right, this is why, like we talk about rat carries bias in you towards an ER strategy, right? So you're creating that here as well.

There's going to be some suspicious people, but.

Yeah.

Yes, sure

Okay. So there's a difference between doing a set of like your 12 rep maximum and your one rep maximum. So there are seven components of force that influence the way that connective tissues behave. All right, two of them, one is rate and one is magnitude of load. And so both have an influence. So the bigger the load, so again, like think max effort squat, that's a ton of weight. And so the way that that load would be distributed would be very, very quickly. So I would need my whole system to be, as they would say, stable to be able to manage that load, right? So there would be almost no yielding. So you have to think about degrees. One end of the spectrum is maximum yield and one end of the spectrum is maximum stiffness and overcoming, right? So all activities fall somewhere in between the two extremes. So you can think about this interaction, like this overlap. And you say, this activity would be more of a yielding action. This would be more of an overcoming action, right? But both are kind of happening at the same kind of places. So I think with Orion, did I talk about that? Was that a box jump in the max effort squat? Did I use that example?

Yeah.

Absolutely, just keep it coming.

Is that why I get a spasm sometimes that will just lock me up to the right for a week?
