Well, you keep on time constraint. So you say, you always have to lift within this time frame. This would be where a gadget that might be helpful. It's like a gym aware kind of a thing where it's giving you a velocity, but it's tracking the time. It's like, I always want you to lift within this window of time. We can increase the load as much as we can, as long as you don't exceed that time.

There's a bump to the right, and there's a bump to the left. The bump to the left is the spine.

Yeah.

I just want to make sure because it becomes less of a, like somewhere in the world, like there's a transition point between a pull down and a row just by jargon, right? You're going to be closer to the flatter, the helical axis is different. Like this would be like the high oblique sit pull down, and this would be like the low oblique, right? You understand? Yeah. But I think you got the right, I think you understand.

Right. So you're going to try to have her hang on to some of that tibial IR that we were just talking about that she probably doesn't have or can't access it. And we've talked a little bit with Zach about ACLs and then how the active rotation of the tibia changes after the surgery. And so she may not be able to control that, which unfortunately could predispose her to a re-injury. So we have to be really, really careful with that. So yeah, I would be worried. Do you work with her or are you just friends?

Okay. Um, I was wondering, would you, in the heels elevated position that you recommended, how deep would you have them go? Like, for comfort, however they feel comfortable naturally? Or, because I couldn't imagine if they don't have the available range, you would drop them all the way down, right?

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?

Do you know what a helix is? It's a spiral. Yeah. Spiral. That's how you're constructed. So everything that you're made of is a helix. So your DNA is helical. Your collagen fibers are helical. Your musculature is organized in helices. Your skeletal structure is organized in helices, right? So everything that you do moves on a helix. So every joint in your body moves on a helical angle. So there's not straight hinges like it's proposed in some of the literature. There's always a twist and a turn that's associated with that. And so your gross structure, so the big structure of you is actually kind of easy to see when you look at a skeleton. And each segment of you moves in a helical manner. And there is a resultant. It's like, if you take all of the helices and we put them together, it slowly, as you move farther and farther into motion, all of these helices start to superimpose and then superpose, just like we were talking about with Zach. So there's a twist and a turn. And so you have a certain ability to twist. And if we looked at somebody with a different physical structure, so you're a wide ISA guy, right? OK, so I think Ian, you're a narrow, right? In the narrow. Yeah, so if we were to watch you guys, you both turn because you're both human beings and have the same relative body parts, I would assume, you would look similar, but there would be a subtle difference in the angle at which your body would turn most efficiently. One second. And that would be when you're turning on the helix, but the thing you have to understand it's like there's not like a singular helical angle. Okay. We use ISA as a proxy measure. Okay. So as a gross measure for your general structure that guides us in how you would turn. So the ISA provides us a measure, so to speak, of how well you would turn or at what angle you would turn. Okay. So does that get me in the ballpark as to what your question might be?

Like a physical pelvis model? Yes.

All right, so for a narrow ASA individual, do they have a great middle propulsive phase? No. So when you take a narrow to sideline, you have to start thinking the bias right away. I've got lateral expansion based on the current shape, but I'm going to create a bias to create the term that you're talking about like right away. So, if I was guiding the rolling, and you've seen me do this, I'm applying the downforce through the pelvis, but I'm also driving the shape of the pelvis and the direction of the short arc roll, because what I am actually trying to do is create that turn from the starting position. Because if I just leave them in middle propulsion, it's not the best place for them to be as a narrow because of the shape of the rib cage. Because I have to create the bend in the ribs.

Yep, that's what it is.

So does that mean these are learned behaviors? These are learned behaviors. So I could take somebody that stands in a late propulsive representation, lay them down, and it doesn't guarantee that they're going to go into an early propulsive strategy, right? They can still be utilizing the late propulsive strategy, right? And I still have the interference.

So then, yeah, so I did kind of want to work my way down as to how the femur and then the tibia are rotating throughout that excursion. So when you started to top your femur is ER because your hip is open, you have your, uh, that's what's getting you that legs out knees out foot out representation. And then as you go down, you're maintaining that, but you're superimposing the IR at the femur through the sticking point. And then as you hit depth, do you see a re-ER. ER of the femur?

Bouncy, bouncy, bouncy, bouncy, bouncy. You don't bounce well. It's not weak connective tissue. It's connective tissue behaviors. So your connective tissues behave more like a leather belt instead of a rubber band. So if you try to stretch a leather belt, how hard is it to stretch? It's really hard to stretch. How much energy does it release when you let go? Not very much. If I take a rubber band and stretch it and release it, that's a lot of energy. So that would be a representation of really stiff connective tissues that don't store and release energy. And then the rubber band would be connective tissues that do store and release energy. Right. And so the activities that you need to do to make the connective tissues behave more like the rubber band type would be the kind where you move into a position and out of a position progressively at higher rates. So you start to expose the connective tissues to the sort of rubber band type behaviors.

I don't understand.

No, it's OK. It's OK. I'm just an idiot.

Proximal femur. OK. So I'm stepping forward. All right. Which side of the pelvis is ahead? So if I'm stepping forward with my right foot, let's just make it very quick. Okay. I'm stepping forward with my right foot. Okay. Which side of my pelvis is farther ahead?

There you go. Okay. So that area has to expand to have a space to turn into, doesn't it?

Okay, so what's the solution? Is the problem of the arch then?

But I just put the leg down on the ground. So I'm going to start to superimpose internal rotation on that ER position. Can you see that?

Okay. And you're a power lifter, right? So you're probably going to be biased towards a wide stance, correct? Awesome. Okay. So your turn, this goes back to Sanis' question here.

So like if you were doing a diagonal medicine ball chop, and you had a left Achilles problem that was really sensitive. And I wanted to recapture the yielding action on that Achilles, I would chop down in that direction, and I would dampen that to teach those tissues to elongate. So to teach them to accept force. That would be a great reason to do the fake throw. Because if I slam the ball into the ground, that's me getting pushed back harder from the ground, which means that I would have an overcoming action of that Achilles, which is like me bouncing across the ground, which might be too sensitive.

So can you say that again, but in a different way?

Of course there is. It's like, anytime you can internalize, you improve self-regulation. That's what meditation is for. Meditation is just for self-regulation purposes, right? So when I coach people to do lazy rolling activities, like the really slow lazy rolling activities, I always ask them, I say, do you meditate? And surprisingly, a lot of people do or they try anyway. And then so I tell them, I say, your lazy rolling is now your meditation because that is a very internalized activity because there's always the self-coaching of slow down, stay heavy, less muscle activity, right? So you learn, they learn how to self-regulate. So it is meditative, right? Where like if you're doing transcendental meditation and you have a mantra, so what the mantra is for is to create white noise, to block out all other thoughts and activities. If I put you in lazy rolling and I say, I tend to this, always think this, always remind yourself of this, I have now internalized. So now you're teaching self-regulation and you're promoting a shape change that might be favorable. So I would lean in that direction. I would give them something to do that achieves the desired outcome versus just an idea.

Good morning. Happy Tuesday. I have neuro coffee in hand and it is perfect as usual. All right. A very busy Tuesday coming up. I'm going to dig straight into today's Q&A. This is with Alex. Alex had some great questions about some of the appearance of the rear foot in helping us determine where somebody may be in space, what kind of an orientation that we're dealing with with the foot. The calcaneus is a really interesting bone. It does bend, it does twist, which is going to throw off some of your so-called eversion/inversion measures. We've got a lot of soft tissue that's attached to it. We've got a fat pad. We've got the Achilles tendon. All of those things will change shape depending on where the center of gravity may be resting on the foot. So for instance, if we're very heel heavy, we're going to see an expansion of the width of the rear foot. We may see a width change in the Achilles tendon as well. And we can make a comparison between two sides as to which side may be more loaded, which side may be more anterior. So for instance, if we were to lift the heel off the ground, now we have a reduction in that width of the rear foot. We're going to see an increase in tension in the Achilles tendon. And so again, whenever we're trying to diagnose or just determine where somebody may be in space, we're going to use every detail that we possibly can. So yes, we're going to rely on our assessment a great deal, but we can also look at these rear foot comparisons to help us determine how we're going to initiate our intervention. So Alex, great question. If you would like to participate in a 15 minute consultation, please go to askbillhartman at gmail.com. Please put 15 minute consultation in the subject line so we don't delete it. We'll arrange that at our mutual convenience. Don't forget to include your question in the email. Everybody have an outstanding Tuesday, and I'll see you tomorrow.

So connective tissue would be like an overcoming strategy.

No. AB, AB. Yeah, like away from midline.

Oh, you did?

We know that with the high obliques, the elbow position is going to push them right back where they started, which is what I do not want to do. What's the easiest way to change the activity to give me the capacity to change? Teya, you're gonna say it out loud for me; you're just gonna mimic on the screen there.

It's like this: the people who would get accused of tight quads never have heel to butt in prone, but they could have heel to butt in supine. You see the difference. So I was analyzing what I'm looking at, which is the capabilities of the knee itself. I don't want to make a judgment call on muscle orientation as far as the limiting factor. It ends up creating an ineffective representation and people make bad choices as to what needs to be done.
