So, oh yeah. Oh, absolutely. So here you go. And there's plenty of evidence of this. So if you were doing a box jump, okay. Let's say I got you on a 36 inch box and you're going to jump and you're going to stick the landing. Okay. Before you hit the ground, the concentric orientation in the musculature that's going to be absorbing the jump. Actually, it's the connective tissue that absorbs the jump. But the connective tissue or the connective tissue just had to be tuned before you hit the ground.

They don't have enough power.

No.

Can you repeat the question? I think I can.

No. Let me take a step back. Yes, and no. It starts that way and then you get more ER on top of it. So then the whole system tries to orient into ER. That's okay.

So let's get this concept out of the way. Walking is a form of propulsion. Rolling is not walking. Rolling is a form of propulsion. Crawling is a form of propulsion. So if you look at it from that concept, that's why the mechanics are the same. So the shape change that's associated with rolling is exactly like walking if you understand what those mechanics are. If you're crawling across the ground, you have to use the exact same mechanics. So again, it's not like walking. It's just that walking and rolling and crawling and all of those other behaviors that get us across the ground in a forward direction are the same. They have to be the same. Otherwise, it wouldn't work because we have constraints. We have a physical structure of constraints that limits us to certain strategies. And so we only have a few ways to do things. And so you're kind of stuck with it. So if you understand what propulsion is, understand what the shape changes, then you'll see like, oh, it's not just similar. It's the same.

Right. I would guess that, and that's really helpful. And that's where it's a little...

Okay, proximal to distal, proximal to distal, proximal to distal. So proximal femur, distal femur, proximal tibia, distal tibia, proximal foot, heel, distal foot. You've got an ER representation. That is not relative motion at the subtalar joint. The subtalar joint is still trying to ER. And now she's pushing it down. And you can tell because of the sequential orientation all the way down. You see it? Okay. Now go back up to your pelvis. Go back up to your pelvis. Okay. And you're going to see that the, yeah. And you're going to see that the, look at the draping of her shirt. Okay. You see how it hangs straight down on the left and then it bumps into her hip on the right. You see that?

Okay.

Yes.

Yep.

Yeah.

So I do have a question about inguinal hernias. Since we were talking about connective tissue questions, I have a client patient who is a massage therapy patient. Fortunately, he's not getting surgery because of COVID—nobody's doing surgeries right now here. So he can't get any elective surgeries. It's not severe enough; it doesn't show up on an MRI. The only diagnostic was that the doctor pushed in and it was soft. He has it on both sides, more on the right and more severe on the right. I was thinking about pressure and how it needs to go somewhere. Hernias occur when pressure goes somewhere the tissue isn't strong enough to handle it. He's a cyclist, so he rides a lot, but he's narrow. He's more narrow than wide. He's a cyclist but not fit or thin. I was talking with him about directing that pressure away from the area, working on shifting him back and getting the pelvic floor more elastic. I don't know if you have any thoughts on that or where else I could go.

You're correct. That's correct. Good morning. Happy Wednesday. I have neuro coffee in hand and it is perfect. Today is Wednesday. That means that tomorrow is Thursday, 6 a.m. Tomorrow morning, coffee and coaches conference call as usual. It's a great Q&A with a great group of people, a lot of great practitioners and strength coaches on these calls, sharing a lot of great information. So grab a cup of coffee. Please join us. 6 a.m. The link will be on my professional Facebook page just prior to the call. Digging into today's Q&A. This is with Manuel, but it's an extension of a discussion that we had in regard to varus and valgus. I believe it was TEA that brought this up a few calls ago. And what we did is we sort of extended this representation as to why we would see one presentation over the other. This is in regards to position of the center of gravity and actually axial configuration. So actually the shape of the axial skeleton is going to help determine whether you're going to see a varus or valgus show up under many circumstances. Then we talk about sequencing is how we would address this in the gym. So those of you that are subscribed to the YouTube channel probably have a little taste of this. When we look at the simple solutions for medial knee pain and lateral knee pain that I posted up there, the medial knee pain is going to be more related to the valgus representation. The lateral knee pain is going to be more representative to the varus representation for those of you that are looking for ideas for activities and then, again, sequencing of events to address these issues. If you would like to participate in a 15-minute consultation, please go to askbillhartman at gmail.com. Put a 15-minute consultation in the subject line so I don't delete it. We'll arrange that at our mutual convenience. Everybody have an outstanding Wednesday. I will see you tomorrow morning, 6 a.m. Coffee and Coaches Conference.

It's a series of turns. Varus and Valgus are described as imaginary frontal plane representations because people take a picture and they slap it on a page that's two dimensional and they say, look, it goes in. It's like, no, it twists in and it twists out. And if you can see the twist, then you can actually help somebody. If you try to mess around with some imaginary plane that doesn't exist, it doesn't work. A very busy Tuesday coming up. We're going to dig straight into today's Q&A. This is with Grace. And Grace has a question that turns out to be a center of gravity base of support type of question. Each one of the compensatory strategies that we talk about influences where someone will be relative to their base of support. So inside of your base of support is your center of gravity. And that's going to determine how much relative motion you have. So as people move towards the periphery of their base of support, this is where we're going to start to see the reductions in ranges of motion. And so there will be a direction in which they will move predominantly. And then this is how we strategize our interventions to determine, well, we have to change actually the shape of the base of support so we can expand that, improve relative motions. So some people need to turn left, some people need to turn right, some people move forward, backward, whichever it may be. But point being is, not everybody is the same. And so we actually take Grace through a little experiment to show her how this influences the ability to sense the superficial strategies that we talk about in regards to how we're moving through the basis of support. So this will be a very useful representation for a lot of people who think that everybody is the same or they have a singular lens that they look through which is often a significant limitation or ability to intervene with people.

So, what you're observing first and foremost is a solution to a problem. You have asked him to do certain things. He has a certain structure, he has certain physiology, and then he is providing you with this is how I do it. That is always going to be the case, regardless of who we're talking about. So if we're talking about a major league baseball pitcher, whether we're talking about an eight year old, whether we're talking about 13 year old, all we're doing is observing a solution and then we are making a determination as to what is good and what is not good based on what we think is best under the circumstances.

Okay.

Okay. Stand up and move back away from your camera just a little bit so people can see you from the waist up. Okay. Your arms are resting at your side. Your thumbs are pointing forward. Correct? Now hold your arms straight out in front of you at 90 degrees of traditional flexion, thumbs pointing towards the ceiling. Got it? Ceiling, the sky in your case. All right. Now, from there, I want you to move your arms into 90 degrees of traditional abduction. Awesome. Now bring your arms straight down to your sides. Do not change the rotation. Your palms will now face forward. Did you notice that? Yep. Okay, so I didn't tell you to turn your arms, but as you move through space, there's a round surface in the shoulder joint that you moved, okay? And so we started with a position where the shoulder was more turned inward. And just by moving you through space, I got your shoulder to turn. So as you're moving through space, regardless of where you're going, there's a turn that's taking place literally at the joint level. You see that?

Pretty much.

No, because he did. Oh, he did double. Yeah, he did double. He paid the price for that one. But aside from that point. But again, it's like he was very, very wide as a human being, but and again had enough structure that didn't really matter where he was capable of producing that type of pressure. Right. So again, you're looking at this from a multifactorial standpoint. But the rules are pretty straightforward. It's like he who produces most pressure wins as far as force production goes. So again, if I have a skeletal structure that allows higher force production, I can superimpose a ton of muscle mass on top of that. I can squeeze the bejesus out of it. I'm going to produce more force. Right. So the basic rule, even in the literature, you know, we go into the scientific literature and you look at the influence of cross-sectional area and force production, it stands to reason that the more cross-sectional area that I do have, my force production is higher.

For sure. And is that situation applicable also to the knee, I guess, is like can you customize the loading to be pulled versus getting compressed?

If you don't have the internal rotation to capture the position, then you don't have like, again, that's why it's not adduction. It's internal rotation.

Anteriorly?

Yes.

Yes. Yes. Yes.

Because you're falling.

You're welcome, sir. Good morning. Happy Tuesday. I have no coffee in hand and it is perfect. All right, coming off the long weekend. Got to dig right in to today's Q&A. This actually came out of a discussion that we had yesterday on the IFAS university call. And we started talking about carries and how each variation of a carry can emphasize a different aspect of propulsion if it is executed correctly. So we've got a lot of versatility in our carries. We could use these in a rehab situation where we're reintroducing force production in somebody and we don't want to lose ranges of motion, but we want to teach them how to manage the internal pressures. Carries are a great way to reintroduce that. If we talk about jumping and change of direction activities in an athlete, we can use it there as well. Again, because of the pressure management that's required under those circumstances, we can increase endurance at high force production. So this would be more like an element where we would be more associated with strongman type activities. And then we can emphasize the recapturing of range of motion via the shape change that's associated with the load distribution of the carries. And that's kind of what I want to emphasize today. So load matters in this situation because the amount of force production is going to be determined by the by the load's use. So greater force production equals greater compression. And so the question mark then becomes, are we trying to preserve or recapture ranges of motion or we merely concerned with force production? Simple test. how hard is it for you to breathe as you're executing these activities? The greater the difficulty with breathing, the greater the compression. Therefore, you're moving closer and closer to a middle to max force production. If we start to see compensatory strategies, so you start to see shoulders dropping or elevating in compensation for the load. Now you know you're drifting into situations where you're using internal rotation compensatory strategies just to manage the load. So you get to decide whether that is something that you're concerned with. Finally, you can look at monitoring your key performance indicators. So for instance, the chances of losing external rotation is greater at the higher loads or higher force productions. And so you have to decide whether that's something that you're willing to compromise on. And so again, monitoring those. So if I had a baseball pitcher, for instance, that is very reliant on having access to extra rotation. If I use too much force production in a carry, I may be compromising that extra rotation. Again, low distribution influences the shape change. And so that's what we're talking about when we're talking about emphasizing different aspects of propulsion. So if I'm writing a program,

So are you in early, middle, or late?

Do you have a mixture of righties and lefties? Or are they all right-handed? All right-handed. OK, yes, that makes sense.

Always. Always. If you take somebody that's on an oblique like on an oblique turn, okay? And then pushed forward. If you try to turn them back to the left, all you do is turn everything at the same time because you don't have relative movement available to you. So you try to push. And like I said, I always talk about, you ever move a refrigerator out of a corner?
