Yes. See how simple this is? It's like crazy simple, isn't it?

That's okay. That's what I figured because I'm, so I'm, can I finish my question quick? So you have the, I've heard you mention it's a component of dorsal dorsal rostral expansion. And then I've also heard you, utilizing it as a technique of compression versus Russia compression on that side. So using it as an element of compression to expand the other side. So I'm kind of curious of, yeah, in what context is

That's right. So two strategies to move: one plane, two strategies—expansion, compression—in the transverse plane. Because it's all rotations. The reason I eliminate these other straight planes is because, for instance, if I'm reaching forward, people say that movement is in the imaginary sagittal plane, that it's a straight plane. The only way you move through that space is to create rotations, and the resultant of my hand or arm being stable in a straight line is the production or cancellation of rotations that allows me to stay in that line. That's why that plane doesn't exist. There is no plane. We use those terms for conversation, but the reality is not that those straight planes are there. The problem is that people express these ideas as if those straight planes are reality and we are somehow fixed in them. Because we talk about humans being three-dimensional or four—I prefer four-dimensional because we have to include the time factor, the space-time continuum. But the point is, we are never moving in a straight plane. So let's not talk about them. Let's speak closer to reality: everything is a turn. Everything has a compressive or expansive element to produce the resultant. What we see is that resultant. If we need to give it a name to have a conversation, I'm okay with that. But let's not express ideas as if that's what's really happening, because that's what screws up the math when they try to calculate forces, and it screws up interventions when people think they have to push you into that straight line. It's like, well, how did that person push themselves into that straight line? Did they use external rotation or internal rotation? Then people get confused and say, 'Well, that's an internal rotation position.' And it's like, 'No, it's not. You're using external rotation or internal rotation to get there.' Then we are concerned about how you did it, because under some circumstances, if you do it a certain way, it works really well; if you do it another way, it hurts.

So number one, this is a turning problem. We know that there are turns that are creating everything that you're seeing. So there are areas that you're going to see that are expanded and you're going to see areas that are compressed literally based on the shape of the thorax. The rule will still apply in that you're going to see this expressed in the extremity measures. So you can still follow that because the extremity measures are based on shape. Okay. And so that's a convenient aspect of the model is that, okay, I just need to identify what I'm looking at, where the compressive strategies are and where the expansions are. Where the limitation may present itself then is where she's not able to change enough. And there are going to be limitations here under these circumstances. And we have to understand that, correct?

So you're superimposing joy on happiness like ERIR.

You got something for 30 seconds. I'll ask on Facebook. I have another one. How to emphasize late propulsion. We didn't talk about that.

Does that make sense? Yes, it does. I have a small question there. So in the land when the front foot is still in the air, we get that late propulsion. Yes, sir. Yes, sir. Yeah. So just a moment before the front foot hits, we pull that ilium back. And then it lands.

Okay. Are there other ways to induce frequency and velocity and variability into those connective tissues without having to jump around and bounce around on a need that's uncomfortable?

Yeah, why? Because you distributed the relative motion, which reduces force production. So now we're back to ERs and IRs stopping motion. So I have to slow everything down everywhere else and let the velocity occur at the elbow to create an area of emphasis of load on tissue to get the tissue to respond in the appropriate manner. Okay, if you wanted to build the world's biggest chest, okay? So we're talking like Schwarzenegger level patch. He still has the best chest. He still has the best chest that's ever been.

breathing into our neck.

Thank you so much.

That takes kind of, at the moment, things like running and that kind of stuff out of the equation a little bit, right?

I'm using that as a representation. Under normal circumstances, if we were talking about a typical physical therapy patient, we might be discussing quadruped activities, which create a concentric orientation posteriorly and allow the pump handle and the pubis to expand forward. Depending on who we're talking about and where we're starting, we must understand our position in space to produce movement. For a back bend in this extreme position, it's all compensatory. Athletes use compensatory strategies to produce force constantly because the amount of force they need to generate is extreme. If we were discussing a baseball pitcher, we'd have the same conversation. At the point of maximum propulsion, they're using a compensatory strategy to stop movement and allow velocity to be demonstrated. For a gymnast, we create massive posterior compression to produce anterior expansion, enabling them to achieve remarkable positions, but these are all compensations.

So, she's going to be close to end game, if not end game. Okay. And so I would refer you to those videos as well. Cool. Cause there's, I believe I have a narrow ISA end game video. Yeah, so severe sometimes doesn't, I should have just made sense. But yes, so you got to start there though. Gotcha. So if she appears to be kyphotic, so what she is, is she's actually bent forward. She's bent forward and that's actually her inhalation strategy. So what she's going to do is she's going to be pulling down on her sternum and up on her pubis at the same time to create that bend in the back, just below the level of the scapula. And that's her inhale strategy. Okay. So, again, it's like, number one, you don't want to be driving rectus abdominis when you're trying to reorient the pelvis. And again, that's why a unilateral strategy tends to be more effective under those circumstances.

Yeah. I mean, clearly, I hadn't really thought about.

Okay. It's gotta be a difficult midground to establish.

Ooh, I don't like that feedback. Um, if, so you're talking about like, if I was running forward and I had to come to a stop or change directions.

You ever see anybody pass out?

I'm totally cool with that.

At the beginning it's external rotation, but later it's becoming internal rotation.

Yes. So there you go. Your foot question turned into a neurodynamics question. Good morning. Happy Friday. I have neuro coffee in hand and it is perfect. All right. Digging into a very busy Friday, some housekeeping items. Don't forget, reconsider, podcast at wherever you listen to your podcast should be rolling, so check those out. Also up on the YouTube channel, probably have another episode coming out, maybe this weekend. So be looking for that. Newsletter went out this morning, so if you're on the newsletter list, then check your email boxes this morning. For those of you on the two weeks sprint, this is your risk and recovery weekend. Time to reflect on where you are in your progress. For those of you on the newsletter list, there was a way for you to measure your productivity so make sure you check that out as well. Okay, digging into today's Q&A. This is with Alex. Alex has a great question. This has to do with the foot as we move through propulsion. And so we initially looked at the setup and the shape of the foot in regards to where we're going to see concentric orientation versus eccentric orientation, compression versus expansion. And then as we move through the propulsive cycle, what is this foot going to actually look like? And then how is it going to look and behave using IR compensatory strategies? So this is actually kind of a big deal as to how it's represented because a lot of things that get represented as relative motions are not relative motions. And certain things that get called, certain things are not as they appear to be. So thank you, Alex. This is an outstanding question. Remember to go to the YouTube channel and get yourself subscribed so you can get all the videos. And then we will see you next week.

Yeah, the first one was up on the left and then the center of gravity moving down and onto that right heel.

All right. Yeah. I get it. If we're skipping the rest because I think I get it, I think you do too.

Morning. Great. So I've been kind of trying to reason through yielding a little bit more. And so I feel like ultimately what I've come down to is first that it's like a change in velocity relative to something else. But the bigger, the biggest description for me between like yielding and overcoming seems to be like the direction of force application relative to the direction that said thing is moving. So for like yielding, it would be against you or it, and then overcoming would be with it. Is that fair to say?

Yes. And then so how, because like the problem with this is like I'm really hard, like having a hard time getting to even feel her like the inside of the foot like she can't get like- Can't do it.

Not specifically. I think my assumption was partially that this would assist with that a tiny bit.

It has to, because they take a breath in and then they don't breathe out right away. Right. And then they release, right? All that muscle tension is released. There's your drop.

Well, okay. So, you know, I'm making this wave for a reason.

OK. So in a hook line position, the band could be a great deal of interference because you're going to end up creating a compressive strategy against the sacral base. If you were in a deeper position where the muscle orientation had changed direction and you put the band around the knees, you create an opportunity to reduce motor output and allow connective tissue behavior to change. You reduce the amount of tension on the connective tissues, and now you can actually create a yielding position. Do you see the difference in the two?

And then because like you're doing so much of that in the way that just becomes like a default strategy for them, even when they're not necessarily moving the heavier weights.
