Yeah.

Oh, there he is. It is going well.

My question is about back extensions and reverse hypers. I was wondering if you would say that with a back extension, the internal rotation comes from the top down, making it more of a later representation, compared to a reverse hyper where the weight is loaded earlier.

Correct.

Awesome. So we're going to talk a little bit about posterior outlet here. Is that OK? So I got this concentrically oriented posterior outlet. It's pushing into the ground harder, harder, harder. So I get this concentric overcoming representation, don't I? Okay, I still got to slow down. I mean an improper representation of pelvis that means my sacrum is going to start to start to rotate, right? Which means that that posterior outlet is going to assume what orientation of the musculature?

I would have them do a squat, like down to a box, stand back up. Like a box squat.

Mm hmm.

The backwards step two?

You know how much I like sled pulls. In a backward sled pull, if I'm mainly working on the trochanter trying to make a distal change, right? If I'm doing more work with the right side where I'm actually forcing the right foot into the ground and not really working the left side per se, without accomplishing kind of the same thing.

Neither. Yes.

I got it. Okay. So, it's like, you wouldn't be careful in that circumstance that they're not leaving the first metatarsal because okay. Yeah.

My Saturday night fever walk.

Do you think that you're getting anterior compression when you're laying on the bench?

You're going to want to look for more internal rotation.

Good morning. Happy Wednesday. I have neural coffee in hand and it is perfect. All right, well, today is Wednesday. That means that tomorrow is Thursday. That means tomorrow at 6 a.m., as usual, the coffee and coaches conference call live Q&A. Bring some coffee, bring some questions, join some great people. We're getting close to call number 100, so we've been doing this for a while. We're getting pretty good at it. So please join us. Okay, digging into today's Q&A. This is from Taya. Tay asked a really good question. It's probably a curiosity for a lot of people in regards to these definitions of open and closed chain and how do we use those. I'm not a big fan of the definition. I think they're very vague. I don't know if they're terribly useful when we consider shape change as the element of movement. If we consider the representation of external rotations and internal rotations in regards to movement. So for instance, if we looked at an early propulsive foot representation and a late propulsive foot representation, both would be considered closed chain, but the direction of forces are actually different and the mechanics are actually different. So again, if they're both considered closed chain, I think it just leaves too much of a gray area and it's too vague. Better to look at this from what direction is energy moving, what direction is force production moving. And again, I think those are much more useful representations. So we kind of hash that out a little bit in this discussion, but still a great question because again, I think that the way that things are represented, if we can be a little bit more clear about the mechanics of such things, it allows us to make better choices in regards to our interventions, especially when you look at it as an early, middle, or late propulsive activity. So thank you, Teya. Outstanding question. If you would like to participate in a 15-minute consultation, please go to Ask Bill Hartman at gmail.com. Ask Bill Hartman at gmail.com. Please put '15-minute consultation' in the subject line so I don't delete it. Please include your question in the email. We'll arrange that at our mutual convenience. Everybody have an outstanding Wednesday. I will see you tomorrow morning, 6 a.m. for the Coffee and Coaches Conference call. Everybody have a great day.

So this makes it better. Okay, so let's say the structure isn't the problem. Is there an easier way to tell if the technique you're doing is incorrect or if maybe you need to try another technique?

Okay, you understand that, right?

So for the past couple of weeks, I've been thinking about the limb twists. And I was thinking about the archetypes. And I was just thinking like the sequence—what the sequencing of the untwisting of the bones is different for the different archetypes. So for context, let's say you had a guy with valgus knees. I would think that someone who is narrow, who's more biased into external rotation due to their structure, would find it easier to achieve valgus knees, whereas somebody who is wide might more often present with varus knees instead of valgus. Sorry—the other way around: varus knees instead of valgus. Because if a wide hip leads to varus knees, right, and he had that proximal external rotation superimposed, it would be easier to get him back into that internal rotation presentation, right?

Because I thought maybe we're going to go like this is medium rare and this is medium that how you do this big thing.

Bill, sorry. Would an early, early reach look the same with the right arm forward, but the thorax toward the arm? No. Yeah, that would be more.

OK. And then when people are, I would say, what are you feeling there? And they'll say they feel a lot of, depending on the degree of trunk lean, they'll feel like the left, you know, left oblique or something: 'Oh, I feel my left, left side.' So are we driving a compressive strategy on that side that's away from the sled as well? Super input—like, is that favorable in that instance because we're trying to drive it? My my thought process originally was driving it from one side to drive the gradient towards, let's say, the left side from if we're talking about, so...

You can, but the best way to do that is for you to create it and then teach them what to feel, since you can lay hands. The best way is for you to create it and then teach them what to feel. It is the best way. You're going to give your verbal cues as you're moving them through space, right? You have to create the sensation because they don't know what sensation they're looking for. This is where you become the better coach, the better therapist—you understand where you need to take them, you take them there the best that you can. Again, you're the guide. What you say matters, how you lead them there matters, the sensations you give them matters. Sometimes you just have to get better at that. We can talk about ideals on a context like this, but the reality is people are hard.

Yes.

Yeah, oh, believe me. I'm all about the process, my friend. What I'm saying is, is like, you can use a specific situation as a representation of the process, right? So you take somebody that. Let me see if I can do this. Let me see if I can do this with my hands. So if I would be looking at somebody, I'm facing them. And let's just say that this is their expansion. Right? I'm looking at them side to side just for the sake of argument. Because if I do this, you can't see my face. And I want to make sure you can see me. So if this is up, and they're going to try to reach up overhead, right? So the initiation of the reach in the earliest phases. So with my arm at my side, and I'm starting to move it up away from me, OK? The expansion is going to look like that. And then as the arm passes that expansion, it's got to expand just above that, and then the rest of it has to come back in. And so the expansion is going upward because that's where the spaces are that I need to get the arm into that space. And then as I pass that space, it goes like that, and it goes back in. Do you see that? So this would be like the lower rib cage. So as I initiate elevating my arm, the lower rib cage is going to do this. And then as the arm passes that space, it's going to come back in because I'm pushing volume upward so I can get up into that space. And then that space closes up. Now if I get to the very end of that range, everything's smushed. And then that's how I can hold a weight over head. So I'm squeezing everything in from the bottom up. Right? So I'm creating the compression and then the compression moves its way up into that space to hold the arm up overhead. Okay? So that's a bottom up representation. So if I have every layer of compensatory strategy that you can imagine, it's like, where do I need to get the space first to start my arm up overhead? I have to get the expansion in that lower aspect and then I work my way up. So that's a bottom up representation. So there's not really an absolute progression. They say, oh, if you're going from the ground, you got to do this, you got to do this, you got to do this. Because a lot of people just come, they're capable of walking in the door. They're upright. And so in many cases, especially in a fitness environment, they're not dealing with some pain related issue. They may have limitations, but they're not dealing with pain. So the decision making is not driven

Don't sway to my right.

350.

So this is where just by nature of the foot and the hand where one is more suited to have weight on top of it and the other one to interact with. It just makes more sense to go for, let's say, a hip airplane or stuff like that. Okay. Yeah. So, okay.

Okay.

Probably not.

So on the back leg, what you would typically see is somebody that can't get what would be considered traditional hip extension, which is IR. On the oblique, yes, because again, you're starting from, you're immediately tipping on this oblique, which is gonna take that right side forward, which is the IR compensatory strategy. So they can't get their leg back behind them.
