Okay.

No bunion. Okay, so that's good.

Okay. So, there's the drop, right? Yes. But if you magnify it too far, you're going to kick them off their foot contact. So you got to be really, really careful. But think about that. You're addressing the ball, you do your waggle and then what do you do right before you take the club?

Which is not a bad thing.

Okay. You must get on the ground and roll around, boss. You need to get some of your muscle activity to tune down. Okay. All right, man. Thank you. I just had a lefty TJ yesterday. Zach Fendrick. What's our ACL question for today?

Now I'm going to tip the ground upward. Okay.

Right.

It's okay. It's okay. That, you know what? If it's not uncomfortable, you're not making any progress, right? Because things that are comfortable, you already know, you're already good with, right? And then, you know, you hope that you never get to the point where everything is like easy and comfortable, unless you're a heart transplant surgeon and then you want everything to be easy and comfortable, right? Good morning. Happy Tuesday. I have neuro coffee in hand and it is perfect. All right. Hey, very busy Tuesday coming up. We're going to dig straight into today's Q&A. This is with Matt. Matt is working with a 400 meter hurdler. Very high level. But Olympic caliber sprinter here with an injury history. So we actually break down a little bit of positional stuff, a little bit of performance stuff. So we actually have some video here of her doing an acceleration where we can make a comparison from side to side as to why she may be having some one-sided issues. So she's got a history, I believe, of hamstring strains on the left side. One of the things that we want to be particular about when we're talking about performance and we have not the same thing in regards to what we're going to be chasing most often with management issues when we're talking about performance because we know that we're going to have situations where a reduction in relative motion is going to actually enhance performance. And so again, as I would always say, it's a management strategy. We have to decide how much of what that we want to give up. There's always a trade off here. So if we're going to get performance, we have to have high force production. If we have too much relative motion at high force production, we get a dissipation of that force. So we actually reduce their performance. Whereas in a rehab situation, where we're dealing with people in pain, we want to try to maximize those relative motions so we can allow the system to sort of figure out how to rebuild that performance as we train them up to their level of performance again. So this is a great question for a lot of people that deal with athletes. So thank you Matt. Everybody have an outstanding Tuesday. I will see you tomorrow.

Well, I appreciate whatever I'm getting out of not your legacy. Now I wanted, well, I have a million questions, but one I would like to know is kind of like I'm getting a bit more familiar with the compensatory sequence, right? It won't randomly appear on an archetype or another. So I wanted to just make sure if I'm doing a good crossover with something else, which is if my memory is correct, narrow the orient from the top down, right?

Okay, so the narrow has a hard time doing that because they're already up. They can't do that. It's because they're already counteracting the down, the torque. They're counteracting the torque. The center of mass is too high.

So do you recognize these like a coxivara?

So with something like that, I think it's easier to see when you stand them up whether they're capturing the positions that you want, whereas based off of even just a little bit of information that I've provided now, I kind of have an idea of what type of stuff she might need in the seated position. Something that I'm looking for to let me know whether she's capturing it in the moment or making the favorable adaptations that I'm looking for, or just an educated guess based on presentation.

He's got to post your lower, if he's going to post your lower compressor strategy, you've got to alleviate that. Then you can go into the upper, upper DR and the manubrium. And maybe it doesn't take that long to alter his compensatory strategies to help with his symptoms, right? But again, but this is why you need to identify where he is and records the strategy, okay?

Awesome. What if I just put the sacrum in that position for the first mode on the right side?

So if it's concentric in the anterior outlet, if it's concentric in the end to your outlet, what is the representation? What is the representation of the public? Is it IR? IR.

Well, that's going to be like a slam dunk for you now, isn't it?

Yeah, it's kind of like we've been talking about throughout this call, it's like there's just no more gradient, right? So there's no more expansion in the direction that they're trying to move. And so this is why, like in everybody's seen this to some degree, somebody, they say, hey, let me see your squat, and they squat down, and then their butt goes backwards and their head goes forwards, right? And they look like a downhill skier, right? Their chest is kind of on their thighs, their butts going straight back and they're reaching forward. And they think that they're doing a great deep squat. And then we just kind of, you know, do the internal head shake thing that they can't see. And then you kind of know, right? So the reason that they're doing that though is, and the reason that they're following that shape is because they're just following the expansion. Right, you said go down as far as you can, and so they're trying to go down as far as you can but but now they're hitting they're literally hitting the floor, so to speak, and then they spread out front to back which is head to tail right. Okay, so if you have somebody that is descending and stops, that's just the point of compression. That's just where they no longer have a gradient. If you can change the context of the activity and prolong their ability to maintain the gradient, you've just increased the depth of the squat. So strategy-wise, I would be on board with that. Right? Execution then becomes a bit of a problem because then that's where the experiment takes place as to, okay, what do I have available? What kind of a structure am I dealing with here? You know, when you've got somebody that's, you know, AP compressed, you've got a lot of ER orientation to deal with there. You know, so you might have to put them in that space. But, you know, from a strategy standpoint, you're absolutely right.

And the upper leg.

Yeah. Well, again, it's protection, it's self-protection. Like if I am certain that I am comfortable, I am confident and I feel good about myself. But the minute you can start to accept the fact that things are uncertain and you're playing the probabilities, then there's a level of comfort with that too. And that's where I think confidence comes from. A younger coach or therapist does not have that because they haven't survived enough failures. I think that's a big deal because you have to be comfortable with the uncertainty. You have to be uncomfortable with the not knowing. You are playing probabilities. If you're 82% correct, then that's a pretty high level of confidence, but with the understanding that there's still an 18% chance that you're going to fail. You have to get comfortable with it because it's going to happen no matter what you do, no matter how good you are, no matter how great a diagnostician you think you are, you're the best interactor, you're the smartest guy in the room. You're going to fail because you're dealing with another human being.

Well, that's what I'm getting at, but what element of force would be potentially affected if I make the weight lighter? Let's say I put 400 pounds on your back and you're going to squat that. I want you to do it in less than a second, going all the way down and all the way back up with 400 pounds on your back. Is that going to happen? No, you have to slow down and do it. But if I put 100 pounds on your back, do you think you can move faster?

We don't use the delay strategy; it is the same thing. They are creating the slowdown because that's a rate-dependent influence. Good morning. Happy Wednesday. I have neural coffee in hand and it is perfect. All right. Today is Wednesday. That means tomorrow morning as usual, 6 a.m. Thursday morning. Coffee and Coaches Conference call. This is call number 113 since we started numbering them. So we're getting pretty good at it. So please join us and grab some coffee and get some Q&A. Great people on the call. Always a great time. Now second item: the applications for the Intensive 19 are open and they are rolling in and it's happening very quickly. So I'm probably going to open this up to the public very soon, probably later this evening. We will open this to the public for a very short period of time to get a couple more applications in because we're really close to our target number. So thank you all for your interest so far. And then we'll get the selection process for that after this weekend because the Intensive 18 is this weekend, sponsored by NeuroCoffee. There you go. NeuroCoffee. That's my commercial. Our official unofficial sponsor, if you will. So please be looking for that. I'll announce that probably on social media in some way, shape, or form. But if you're on the mentorship list and you've been waiting to put your application in, please do so very, very quickly so you get that in. Because again, once I open it to the public and we've only got a few spots left available, we will shut that down very, very quickly. All right, getting into today's Q&A. This is with Christian. Christian had a knee question. As with all other aspects of the movement system, the knee goes through the propulsive cycle. So there are elements where it is exposed to an ER bias. There are elements where it's representing the IR bias. And if we can understand that a little bit more effectively, number one, our examinations get a whole lot better. And then as do our interventions. And so we're much more successful in situations, especially when we have some sort of what we could refer to as a mechanical knee problem that's not associated with the structural change. A lot of times, like all those special tests that you get taught in PT school are not terribly helpful in any way, shape, or form in a situation where somebody might walk in the door and they got an MRI and says, hey, my knee is structurally intact, but I'm still having a lot of pain. It's like, how do you examine that knee? How does it become useful? We need to understand how this knee moves through the propulsive cycle. If we can understand that, like I said, we get a whole lot better. And that's what Christian's question is all about. So it should be useful for a lot of people that are dealing with some knee issues or you have a client that has maybe a knee problem that you're trying to work around. Again, this will be very helpful. Thank you, Christian. Everybody have an outstanding Wednesday. I'll see you tomorrow morning on the Coffee and Coaches Conference call and be looking for the opening of applications for the Intensive 19 to all of you fine folks. I will see you tomorrow.

I'm a little afraid, actually, too. I get it. I have moments of creativity. I just don't know if I can pull that one off. Good morning. Happy Tuesday. I have neural coffee in hand and it is perfect. All right. Busy Tuesday coming up, a quick housekeeping item, the Intensive 19. I'm going to lock those dates in probably by the end of the week. It'll be in September, probably later in September. So be checking your calendars for that. Applications would open to those of you on the mentorship list. You can go to any post on billhartmanpt.com. At the end of those posts is a place where you can get on that list so you are first notified and get first dibs on application for the Intensive 19. Okay, taking into today's Q&A, this is with Manuel. Manuel had a question in comparing the so-called back extension exercise, which is really by traditional representation, it would probably be more of a hip-oriented activity. In comparison to the reverse hyper, also probably misnamed and misapplied. One representation is an early representation of internal rotation. The other is a representation of late internal rotation, both misused, both misapplied and poorly executed. So there is a video on YouTube where we do discuss the reverse hyperactivity. So please go to that for any technical understanding that you may need. But this is a great discussion as far as how you might apply these two activities at certain times. And then we move it actually into a weightlifting perspective. So Manuel's a weightlifting coach. So we talk about where we would actually apply each of those activities to enhance our ability to perform the Olympic lifts. So thank you Manuel for this question. Everybody have an outstanding Tuesday and I will see you tomorrow. Manuel, the beard is looking strong by the way.

So, the low propulsion test asks: can I produce immediate righting into the ground directly below my center of gravity? Or did my center of gravity go forward such that I cannot do that? That created a little bit of an orientation. Now I'm using orientation to create the IR because that's what she was doing before anyway. That was her interference.

Yes.

Okay, so now we're dealing with a complexity issue. You know what the end game is, like if you're trying to coach a split squat on someone who has never done a split squat and you're trying to chase relative motion at the same time, good luck. It doesn't happen. You go back to Nikolai Bernstein—one of the things you recognize in people of low skill is the degrees of freedom issue. People will lock things together to reduce degrees of freedom in a complex, unfamiliar situation. That's what happens: as soon as you teach someone something they've never done before, they won't use relative motion because number one, they have no idea what you're talking about, and number two, it's very difficult to execute. So they take the theoretical 244 degrees of freedom in the body and try to lock it into as few as possible, locking joints together and moving segments together. Then you have to put them in a more comfortable position—take gravity away, bring them down to the ground, reduce internal forces they have to manage, lay them on their side, teach them to feel contact with the ground, or use static positions to teach appropriate sensations to attend to. You have to create a movement vocabulary for them. You know what you want, but if you speak your language to them, it's like me speaking Portuguese—they don't understand. So you have to decide how hard to make this and where you have the greatest access to what you're trying to do, then slowly increase the complexity.

Not necessarily. What you're going to look at is, if you look at a rear foot and that rear foot is kind of bent inward, go to the mirror and look at your feet on the ground.

What have been yesterday?

So I'm unweighting. So the front foot elevation unweights the front leg. The chop unweights the front leg. Do you see it? And that a lot, so if I take gravity away, I reduce the forces that they're trying to manage.

No, so it can't be the same because the starting conditions are different, right? So they're trying to manage the same forces with two different physical structures. So again, the narrow ISA turns on a more vertical axis, so it's more up and down, and so they turn almost in a flat turn, okay? The wide ISA turns on an oblique, so they're on a diagonal axis. So the strategies are different. Where the first move for a narrow ISA would be to move forward on the left, a wide ISA would move back on the right. because again, they're tilting on a different axis. So hold your arms straight out to the sides. Straight out, awesome. So I'm gonna put an axis that goes straight down through your head and you're gonna turn to the right, okay? So just take your, yeah, okay? So keep your head facing me so you can still see what we're doing. There you go, good. So that's a flat turn. You understand? Okay? Now hold your arm straight out to the side. Okay. Now drop your right arm, raise your left arm so it's on a diagonal. Now turn to the right. That's not the same, is it? No. So the horizontal representation is how a narrow would turn. The diagonal representation is how a wide turns. Okay. So your center of gravity moves differently. Does that make sense? Yes. I see you shaking your head. Yes. Okay. Does that answer your question? Yes, it does.

Yes. Yes, I'm with you. But I'm going to make you do a demonstration. Is that okay? So you'll understand. Okay.
