I'm getting tripped up a little bit with the idea that as a general principle, if we're just looking at magnitude, increased load is going to drive a stiffer representation. But then we're talking about like a power lifter, like a really stiff person sometimes needing that load to get the yield. I'm having a hard time getting those two to play together.

Okay. I would think it's good.

It's more about, like I said, it would be more about the differential between the two. Okay. It's going to it's going to yeah because again it because it's an up and down thing more than anything else.

There you go. All right. What's up?

And so now we have to look and we have to say, okay, where is this kid in this process? What are we doing? So I would look at this from the perspective as he's 13. How many scholarship offers does he have so far?

You mean standing up activity? Okay. Well, then also chopping, but not, uh, but in early.

That's called Todman's paradox. And what this is, it literally has everything to do with round surfaces, like moving on a round surface.

Thanks, Bill.

Yeah.

Yeah, not putting any excessive fatigue on it.

Average people don't run fast.

Gotcha. Yeah.

Back to Maxpe. I don't know.

So think about where they're limited. If the straight leg raise is limited, that means they're either moving through middle propulsion too quickly and getting to a late strategy or they're landing towards that late strategy. Most cricket bowlers are narrow stances, right? Because of the release point. In many of those cases, you're looking at the late propulsive representation. They're either moving very quickly through middle, therefore they don't have a middle—they're going around it or over the top. They would not be able to capture the early representation. When they strike with their right foot before making their final stride, they're going through early, middle, and late, but the foot is on a sideways orientation. They're rolling over that inside edge. This is like what we were talking about with Jen with her pictures—capturing that middle representation on the right foot. If I don't capture that as I push myself into the final stride, I won't be able to land that foot in the proper orientation in the direction I'm trying to throw. I won't get the medial foot contact down. They might land a little more laterally on the foot, and then they won't be able to bring the medial foot contact down. They immediately go through where you would want middle, so they have to anteriorly orient to create downward force, but it doesn't allow the normal foot contact. So what I would do is spend more time with left foot forward lead activity—like a left leg forward split squat with front heel elevated. That would create the sacral orientation to create the delay on that lead foot. You may also have to go back to the right side. They might not have a good representation of middle propulsion on the right side either. You would have to do that first. Think of this in sequence: if I can't capture the right foot position, I won't be able to capture the left foot position.

All right. Yeah. There's nothing to think about more as a fall as opposed to actually.

It's a pattern that I see with weightlifting. A lot of times I'll see an athlete that they have a left shift in the squat. And so what they'll do is that they'll compensate by really overemphasizing the left leg. Correct. So it's not so much that there's a hip shift, but it's more that they just push that leg out to get the ER. They also tend to be in the upper body, they tend to be tighter on the right side, like tighter, less shoulder flexion on this side. So I feel like they're kind of like buried. They're kind of doing this in the upper body. It feels like they're turning into their right side so they can't find the IR. And so, and another aspect of this case is sometimes the right foot is back on the jerk. So they do left foot forward, right foot back. The right foot tends to be a little bit turned out. Not too much, but they just can't find that IR. Correct. That's exactly correct. Yes, sir.

There's middle. Anything behind that, if I take the leg behind that, that is a late representation because I have to push against the base of the sacrum. Anything where I take the leg across in front of the downside leg involves a delay until the foot gets across to the ground and I start to roll the pelvis over. You have to look at the position of the sacrum. Don't look at the position of the leg. You're not rolling the legs. You're rolling the axial skeleton. Pay attention to what's happening at the axial skeleton in regards to what's moving faster than something else. Anytime I have to slow something down, I have to create a delay strategy. If I'm in an ER representation—leg either behind or in front—then if I'm not pushing the base of the sacrum forward, that's the delay strategy. That's an early representation. If I'm slowing it down, it's a relative rate. If I'm perfectly on my side, where the sacrum is squared to the front, that is a middle representation. Therefore the delay strategy would be more inferior towards the apex of the sacrum, because the musculature there has to reduce concentric orientation towards eccentric orientation to slow through the middle range, since the pelvis is now in an IR representation. It's just like taking a step forward.

There you go. Okay. Yes. Yes. Yes. Okay. So, think about this. So, when they're loading that hip, they have to be able to move towards nutation or they will make a compensatory movement or strategy, right? Yes. So, they're anteriorly orienting. So when you're looking at the force plate analysis, are you only getting like up and downward pressures?

Yeah. So back in the olden days before you were born, refrigerators didn't have wheels. They were just on legs and you had to move one side at a time, kind of a thing, right? And so what we don't want to do is turn people like a refrigerator when we're trying to reestablish movement. So you need to bring them back so you can recapture some of the relative motions that should be available in the pelvis itself. So now we want relative motion in the pelvis, then we have actually the capacity to make a turn. Until then, you don't.

So my question is... So go back to the... One second. Go back to the hip IR on the second athlete.

So I want to ask if this compression expansion model can apply to sprinting and I can know if somebody would be biased to some form of running if I know what his ISA is or what his hip measurements and all other measurements are. Because I see people say somebody's heel striking or somebody is running with their feet pointed way out. Like this morning itself I had somebody who was running with feet pointed way out and he lacks external rotation. He had good amount of hip internal rotation and as far as I could reckon this guy had a forward orientation of the pelvis. He had a flat back with exaggerated thoracic and cervical curves. So I just want to know if that can apply to sprinting.

So you have a representation. And you have a thought and you say, if this is what I'm seeing, this should be something that would make a change. It should influence this in some way. And I make a prediction based on what I think is going to happen or what I want to happen. And then I do that thing. And then I wait and I go, what happened? So I just updated my information. So now by doing an intervention, I have more information to make the next decision. And so, have you ever been on a sailboat?

On the right side. It's more over the right side than it is on the left side.

All right. Well, today is Wednesday. That means that tomorrow is Thursday, which means that we have the coffee and coaches conference call tomorrow morning at 6am. Please join us. These groups have been great. The calls have been awesome. We are really enjoying these. We will continue them. But again, please join us at 6am tomorrow. Today's Q&A comes from Anthony. Anthony asked a question at askboharmonygmail.com in regards to bench press. So he actually watched some of the recent calls that I did with Ben. Ben works with a lot of powerlifters. So we talked a lot about powerlifting. And Anthony came in and he says, Hey, is there anything that you can do to help me with my bench press arch? Well, guess what Anthony? We sort of answered this question almost a year ago. So I went back into the archives and dug it up for you. And so I'm going to replay that for you this morning. So I think you'll find it useful to answer your question. Just keep in mind that as we try to gain performance in powerlifting and especially using some of the things that I've mentioned in this video, there are secondary consequences that you're going to have to pay attention to. So please take that into consideration. Okay, if you would like to participate in a 15 minute consultation, please go to askbillhartmanageemail.com, and put '15 minute consultation' in the subject line, and we'll set that up at our mutual convenience. Otherwise, I will see you tomorrow morning at 6 a.m. on the Coffee and Coaches Conference call. Have a great Wednesday. So Renna says, this is more of a powerlifting related question. What strategies, both breathing and postural, can those with narrow and wide ISAs use to maximize thoracic extension in the bench press as it relates to the rib cage? This is mostly regarding the setup to execute the lift. Any info on the role of ISAs in proper bench press execution would be much appreciated. Okay, so now we get to take this concept and what we're going to do is we're going to physically shape somebody into a position that's going to increase bench press performance. So let's talk about powerlifting in general first and foremost. Powerlifting is about force production under very, very heavy loads. There's no time constraint, essentially. Like we would see in Olympic weightlifting, which has a time constraint because of the technique that has to be used. So if you can grind out a bench press in 10 seconds, so be it. As long as you complete the lift, that's all that matters. So we have very, very strong exhalation strategies and very, very high levels of concentric orientation. So we want to minimize eccentric orientation as much as possible, only enough to allow sufficient movement to be accessible to execute the lift.

Right, it has to slow. So when the foot hits the ground, the leg is no longer moving forward, but everything else is. And so I have to slow that side of the axial skeleton down so that I can begin to try to advance the other side. So yes, so what a yield is, is the delay strategy on that side.

You're going to get crushed like a paper cup. OK. All right. Here you go. You ever smashed a pop can?

Yeah.

Well, it's recorded. So there you go.

We are recording. The timer has started. Misha, what is your question?

I don't know about that. Let me clarify something first and then we'll go after your actual question. So we're dealing with a very complex situation when we're dealing with humans. Humans are a complex adaptive system, and what that means is we don't fully understand it. That's why we use a model. A model is a representation that allows us to make decisions and to intervene effectively with a system that we do not understand. So, I know the model is wrong—I don't know how wrong yet, but I know it is. I know that the way it has evolved is that it becomes very useful. But we always use rules of thumb, heuristics, and modeling to help us make decisions because we don't know; we just don't know. So there's nothing wrong with establishing a rule of thumb that is useful and effective. I have no issues with that whatsoever. So let's make sure that we understand that. Now, going to your question, it's somewhat vague in your representation that you say, 'I need to include lower body.' So when are you not including lower body? We need a qualifier in that regard so we can understand each other. So when you say 'including lower body,' what do you mean by that? For instance, you mentioned an overhead press or something like that. If I'm standing up, the force I'm applying upward into whatever resistance I'm pushing upward starts from the ground, and I push up. You see what I'm getting at? We have to be very clear as to what you're referring to when you're talking about including a lower body activity. So it's lower body under what circumstance? If I'm doing a suitcase carry, for instance, am I not involving my lower body? Yes, you are. Am I not? Am I not including internal pressure management? I am. Right? So we want to look at this thing from the perspective of how the entire system is interacting. So do me a small favor here and clarify exactly what you have in your head when you say this so we can have a reasonably intelligent conversation. Don't be vague and generalize—pick a specific activity that you have in mind when you're saying this, and then we can go from there. So now we have a point of reference that we can discuss. Let's say a squat. Okay, awesome. Gotcha.
