What's not a muscle energy technique?

An arch in your shoe? Yes. It may behoove you to do so. And again, it's like a shoe representation for you if you're pushing into the ground. So that's what that low arch means is that you're pushing into the ground. So it just depends on whether you've got an ER foot that's pushing into the ground or if it's an exaggeration of what would be represented in middle. And so there are certain adaptations that can take place here within the foot that you might need to accommodate, generally speaking. The safest way to do this is to get a shoe that has a little bit of structure to it so you can feel where your heel is in space and a little bit of an arch because what the arch does is it slows you down from going forward too fast. And so if you're pushing into the ground that you're trying to get yourself forward faster. The arch slows your foot down. And so it may allow you to actually reduce some of the muscle activity that we were discussing before, allow you to capture some of the internal rotation, which would be an early representation. So again, early propulsion is an externally rotated foot that has an arch, but the tibia is behind the foot and moving forward more slowly. So flat shoes, you know, like sandals and barefoot walking is not necessarily your solution.

How do you feel about getting on the floor, boss?

You're kind of on the outside edge of your foot?

Can you just- Are you doing a release? Are you doing, are you doing a fake? A fake. Okay. Anytime, okay. The implement. Okay, is the guts. Do you understand that?

Okay, now I understand.

I understand your dilemma. I just don't know if there's necessarily a great solution because you have a lot of sound that you're trying to block out, which then your vocalization becomes more important. And so this might be like the exception to the rule of saying less, where your voice becomes the guidance. And so to overcome Bon Jovi, you know, you're gonna have to hold somebody's attention. So that might be a little bit more of a continuous instruction—not giving more details, but giving the same details more times.

Okay. If you do the fake throw, do you know when you're going to stop? But you know you're not going to let go. The difference between the two is I start slowing down sooner. So if I'm going to release, I don't have to slow down at all. If I know I'm not going to release, I start slowing the ball down sooner. So the duration of the yield is extended, but the force of the yield is lessened.

So, Brian, I hope that's helpful for you, so you can see that there are definitely prerequisites that are required to execute the McGill's Big 3. We've got a lot of information up on YouTube as to how you can reacquire this middle propulsive strategy, internal rotation, and then successfully transfer these to any number of exercises.

You don't. So there is no position where you have all measures available.

Oh man, everybody hold on.

Do you want to drive that position in a hand that is internally rotated relative to the radius?

So when you're actually executing the heel to butt, pay attention to the patella. If the patella gets pulled to the extreme lateral aspect of the knee as you're bringing the heel to the butt, you'll see the patella move laterally. Now it's going to go there anyway, but to the degree in which it does so, and then pay attention to the tibial tubercle as well. So if you have a tibial tubercle that is turning into external rotation as you bend the knee and you get good heel to butt, and most people that have an eccentrically oriented vastus medialis obliquus as you flex the knee by tradition, it's very, very soft—like crazy soft. And so it's very easy to take the heel to the butt under those circumstances. The way that you're going to understand it is by executing many of them. So every opportunity that you have to do a heel to butt measurement, do it and then pay attention to what you're doing and then pay attention to what you're observing.

Thinking about this, Manuel, especially as the loads increase, the amount of force I apply has to increase. Which means I'm going to squeeze you more front to back. I'm going to stick you more in a middle representation, which means I'm going to be taking away your ER. So I have to orient harder into ER, which means I have to twist harder into IR. Same process as we were just talking about in the work journey.

So I would like to understand how different is fluid shift to shape change? Or if it's just the same thing where I am right now thinking of fluid shift as localized adjoint and shape changes.

Hang on a second. Can you blow that up?

So when you say use it appropriately, the thing that we have to have in place is the context in which it's going to be applied. So if we were just talking about walking versus throwing a baseball, the phases of propulsion are very similar, but how you would produce that might be different because of physical structure and because of how they're producing internal rotation. So when you say internal rotation, is this relative motion at the hip, or is it a compensatory strategy to drive force into the ground to a greater degree? I might use an anterior orientation because that increases the amount of force that I can apply into the ground. So again, we have to be very contextual with this and progressive. If you think about acquiring relative motion of internal rotation on the table, as soon as I take you out of that context, I've just changed everything about the strategy that you would have to use because I have reoriented gravity and increased the force demands upon you. And then I'm going to move you into a context where we now have seven components of force to deal with. The magnitude of the force matters, and the rate of force application matters. Again, we have multiple influences that we have to account for regarding what strategy you will utilize. As you move into higher and higher force production, you will lose relative motion because it is inevitable—you cannot produce a higher peak force with relative motion. Motion has to actually stop for you to apply that force into the ground. Over what duration do we need to apply this force? For example, in a max effort squat with 400 pounds on your back, the duration of your peak force output is going to increase because it takes longer to get through that phase. If you were using half of that weight, it would be a much smaller representation based on time because you can move the weight more quickly and the acceleration is higher, resulting in a shorter duration where you would be exposed to that peak force. This requires a very specific context. Many people might not recognize this because they make an assumption like, 'Oh, you have internal rotation now, so you have the capacity to do this.' Not necessarily. This becomes problematic when you're working in the athletic realm because physical structure is going to determine how you apply forces to the ground and what durations you have available to you. For example, a narrow-stance individual has a very small window of opportunity to apply force into the ground because they don't have the shape change that produces maximum force into the ground.

Yes.

Can't help it.

Header gut? Can you guys see that movie? That's Boy Scout, Bruce Willis, greatest actor of our time. Okay, quick story. Bruce Willis comes into his house. He finds his best friend with his wife, and he's very angry about that. And he sort of forgives his buddy, but he says, I can't let you walk away without punishment. So he goes head or gut, which means I'm going to punch you. You get to decide whether I hit you in the head or in the gut. Okay. So if I hit you in the head, right? That's location number one. There will be a wave when I punch you in the head that goes through your system from your head, you understand? Okay, if I punch you in the gut, there is a force that will be applied and it will move in a different direction, okay? Because of the location, because of the angle of attack, so to speak, the wave will propagate in a certain direction, okay? If you were to throw a punch, okay, you would pull force from the ground upward into your fist. And as you make contact, it would reverse gears and it would go the other way. Okay. And so based on the points of contact, that's going to determine where the wave would start and then what direction it can go. Does that, does that clarify?

Sweet.

You get some comic books or something to read because that's a long time to be thinking about it.

Oh, I see what you're saying. Yes, so all you have to do is have, so think about what you're driving, right? In regards, so you're fixing the hand in space. Is that fair? Like it's in space. And then you're, so you're driving the relationship from, so if I'm laying on my side and I'm twisting my arm, right? I'm driving the range of motion from hand to shoulder. Okay. Um, so that hand is fixed in space. So this is, this is the dilemma with calling something open chain versus closed chain, right?

Well, let's talk about the end representation first. So we have an understanding of that. And then we can sort of progressively strip these things away. So if you've got somebody that has limited rotation, which I'm sure you're evaluating it in some way, shape, or form. So if you've got an upper DR that is compressed, people will complain about upper trapezius, lower cervical spine kind of stuff. They don't feel stiff; they're the people that try to back out of their driveway and can't turn their head. Hopefully they have cameras in their car where they can actually see themselves back out of the car. If you've got upper DR compression, you have a lower cervical spine that is in an IARD force-producing position, so it is going to be compressed as well and that is going to take away the turns. It doesn't mean they can't turn their head at all, but it's going to be upper cervical spine that's going to be producing that type of rotation. Now, if you were to apply some form of manual therapy, the goal would be to restore the expansive capability of those segments to allow them to start to turn again. So this comes down to what are you going to be your choices? Because you do manual therapy as part of your gig, right? And so now you're going to have to make a really well educated decision as to what approach you're going to take with this. Because if you've got upper DR compression, I got news for you: you got AP compression throughout under most circumstances. Are they wide ISA people?

Yeah.

Yeah, should we ask Alex about this one?

Yeah.

You can call me Bill.

Okay, so the pros and cons thing doesn't work because it equates good and bad. Everything comes with its weight, and you have to take that into consideration. You could draw a line down the middle of the paper and list all the good things that could happen and all the bad things that could happen, but again, they're not equivalent. You have to understand what the potential influences may be. You play out scenarios and then make a decision. I don't dwell like everybody else does, I ruminate like everybody else does, but the best thing to do is to try to get things out of your head and then write it down. That's like self-therapy when you don't have somebody that you can talk to. My wife is terrific as far as being the greatest listener in the entire world. She will let me talk endlessly if I would, and that's great to have a sounding board who can reflect things back to help you see where the weighted measures actually are. But I don't spend a lot of time making the decision itself. In most circumstances, as great as we can be at predicting, we're not good predictors. As great as we are at determining the consequences of our actions, we don't know what's going to happen. So we make the best choice that we can within a reasonable timeframe. Once you have accumulated the appropriate information and weighed that information, then don't spend a lot of time making the decision because more time usually doesn't help. It just becomes layers of second-guessing. So you make the decision based on your weighted measures and then move forward. For instance, we just moved IFAST into another facility, which was a big decision. Mike and I went back and forth as we acquired as much information as we could. Then we said the best course of action was to make the change, and that scenario still plays out.

All right.
