I'm trying to reconcile in my mind when we get towards end game presentations in narrows or wides, what their phase of propulsion looks like in one side of the body compared to the other side of the body during that end. So when we end up say we're going to a wide I say heavy over on the right oblique push right forward and To me, like a media, when I sort of look at that, I'm thinking in my mind that we're sort of later on the left-hand side than we are on the right-hand side being pushed from the back initially and then over onto the right. What I don't quite... I guess what I don't quite get is when we end up over on that right oblique, if I was to look at that in respect to like a gate cycle, I would think that my sacral orientation would be kind of leading into the early phase on the right leg would be pointing to the left, right? So axial skeletons turning to the left in a right step, for instance.

Good morning, Bill. I've got a question, and it's probably a very quick one, I guess, for some people. But for me, I still find it a little bit confusing. I'm trying to reconcile in my mind when we get towards end game presentations in narrows or wides, what the phase of propulsion looks like in one side of the body compared to the other side of the body during that end. So when we end up say we're going to a wide, I say heavy over on the right oblique, push right forward. To me, when I sort of look at that, I'm thinking in my mind that we're sort of later on the left-hand side than we are on the right-hand side, being pushed from the back initially and then over onto the right. What I don't quite get is when we end up over on that right oblique—if I was to look at that in respect to like a gate cycle, I would think that my sacral orientation would be kind of leading into the early phase on the right, with the leg pointing to the left. So the axial skeleton turning to the left in a right step, for instance.

So you're going to step forward with your right foot.

Is that what you're saying? My axial skeleton, the sacrum, is going to be pointing to my left.

If we talk about your sacrum, let's just make it simple. Let's just talk about the sacrum. If you step forward with your right foot, your sacrum is going to be facing the left.

My sacrum is going to be left, yeah.

It's going to be facing the left.

Facing the left, yeah.

As you put weight down on that foot and you start to capture internal rotation, you're going to start to create the delay on that side. As your center of gravity comes up and over the leg, you better have a shape change.

Got it. You just cleared up the question.

Let's talk about this because it's not a singular representation because it all has to do with where the center of gravity is and how far forward it goes.

Okay.

Hey, quick question, Matt, have you ever had a big heavy barbell on your shoulders? A couple of times. A couple of times. How tall do you think you were relative to when you're standing without the barbell on your shoulders?

Well, as you know, I'm normally like six foot three, so... Well, life has beaten you down.

There's no question about that. And it's like having hung out with you for a little bit, I understand. I understand how difficult it is to be Matt Hamilton, you know, living the life that you do on the ranch and all. So just think that through for a second. Okay, so you're going to put a big heavy barbell on you. Are you going to get tall? Are you going to get shorter? Sure. Right. Straight down into the ground, right? Okay. Cool. As you step forward, this right foot, as we were talking about, and you start to put weight down, and you come over top of the leg, but that's the general gravity moving forward over the foot. That makes sense, right? Yep. Okay. Do you think you're getting taller or do you think you're getting shorter? Sure. Yeah. Okay. And then as you pass over that leg, and you start to take the weight off again and you're pushing off that foot to shift your weight over to the other side. Do you think that leg is getting longer or shorter?

The foot I'm pushing off is getting taller.

Yeah. Okay. So where are they? Like when you're looking at somebody, where are they? Are they getting smushed down or are they coming back up?

It's relative one side to the other.

Yeah, but now you got to look at this. So keep in mind that every time we make these steps and your center of gravity is oscillating from side to side. And we're talking about walking right now, not just standing still. You have compression and expansion, compression and expansion, compression and expansion, compression and expansion, right? But if you're just standing there and you are limited in your propulsive capabilities, you will stand in the propulsive phase that you are limited to.

Yes, yes. Yeah, that starts to make sense.

And so what our measures then reflect is they tell us what shape you are. They tell you the physical shape. So I know where you are in the propulsive cycle.

So here's a question. I'm trying to understand that now. Is there any way that someone could be later on their right hand side, later on their right than their left, given the order of the compensations that occur, the compensation patterns?

Most likely I wouldn't consider them later. But because the center of gravity will end, right? You have two options: you allow yourself to be compressed downwards, you get pulled down, or you fall over your foot. The last strategy that you will have is some way to just try to stay inside your base of support on the right side. Again, this is like how far forward are you? How hard do you have to screw yourself back into the ground so you don't tip over to the right?

Yeah.

And so the last strategy that you will have is some way to just try to stay inside your base of support on the right side. Yeah. And again, this is like how far forward are you? How hard do you have to screw yourself back into the ground so you don't tip over to the right? So again, from a timing standpoint, you'll be hard pressed to be later on the right than you would be alive because that's where the space is closing from that side, right? Yeah.

Yeah.

So again, from a timing standpoint, you'll be hard pressed to be later on the right than you would be on the left because that's where the space is closing from that side.

Cool.

Good morning. Happy Tuesday. I have neural coffee in hand and it is perfect. All right. A very busy Tuesday. It's intensive week, so there's a lot of stuff to do. By the way, we will probably announce Intensive 20 really soon after this weekend. So I gotta get through Intensive 19. We're going to narrow down some dates for us, and then we'll be ready to rock and roll with that. So if you're not on the mentorship list, please go to billhartmanpt.com. Go to any of the blog posts and at the end of the blog post you can enter your email so you're on the list to be notified first when we do announce Intensive 20. Digging in today's Q&A. This is with Alex. Alex is mobilizing a painful knee. One of the things we want to recognize is that no matter what intervention we're using, we're trying to promote a shape change. So if we're doing a manual therapy or we're using like a ground-based movement of some sort to promote a shape change, we can emphasize a focal representation or we can go after a distributed representation. And that's kind of what we're talking about when we're talking about the setup of what he's doing with the knee mobilizations. So in some cases, we want to constrain elements of the system to create, to magnify the focal representation that we're trying to influence. And in other cases, we're trying to promote a physical shape so we get a more distributed representation. Again, same rule applies whether we're doing exercise-related interventions, whether we're doing manual therapies or any other type of influence when we're trying to enhance movement under some circumstances. Sometimes we need a local shape change. Sometimes we need something that's more distributed. Always keep that in mind. So thank you, Alex, for this question. Gonna help a lot of people. Everybody have an outstanding Tuesday and I will see you tomorrow.

Good morning. So I have a procedural question. For example, let's say you're trying to bring a Y back on the right and you want to do like an early Nemo on both sides.
