So if you're choosing from your oblique sits, you probably want to put them in a lower oblique set.

Well, it's just the definitions. The original definitions are just kind of vague. That's what my problem is. What we're really talking about is what direction the energy is going in these activities. Am I going from proximal to distal or distal to proximal? That's the better representation of this. It's just harder to see. So can you give me a specific example in mind that we can use as a frame of reference to clarify your question?

Right. Yeah. I was just thinking about somebody I had doing a high oblique sit and ended up pushing them laterally.

That would be the most extreme representation of what we're talking about.

Yes. That makes a lot of sense. So what do you usually go by when you see someone? How would you know like someone's pelvis is bigger than the rib cage? Like for some people it's obvious.

Okay. So magnitude. So the, the, the, you know, F equals MA. Take your MA and make the F bigger. So there are two ways to make the F bigger, more mass, more acceleration.

Yeah.

With the implement that you use to attach to the hip also provide a constraint for a compressive strike like where you're placing that.

I don't know. So you're increasing muscle activity. Is that what you want?

Talking about the foot, like base of first metatarsal and base of the big toe, right? Awesome.

Everybody has superpowers, but left alone, those superpowers will destroy you.

Bend.

If I don't fall to the ground, not very.

Yeah.

So they will tend to take a little bit more time to produce force. So they're not as fast. It doesn't mean they can't produce force. It just means that they might not be as fast at it, OK? Because they have a little bit more of the eccentrically oriented representation of the anterior tilt of the pelvis. So they have to push it up to produce the upward force. So they're pretty good at downward force. But as far as being quicker to produce it, not necessarily so. But the potential, I mean, again, everybody has the potential to produce the force. And there's a couple other factors, not just a wide versus narrow that influence how well you produce of course. Again, because some people have more downward velocity internally, and some people have better upward velocity internally. And those are going to be the guys that you see that are the really good jumpers or really good sprinters or the guys that have a bias that allows them to stay in the air longer. So like legitimately they can stay in the air longer than other people can because the internal dynamics, the fluid dynamics internally allow them to easily produce upward velocity versus the people that are kind of stuck to the ground and have like a four inch vertical jump. Yeah, it's not that they're weak or anything. It's literally that their internal dynamics are shoving them into the ground at such a high velocity.

Yeah.

So it's going to bring the front leg in with it. Because again, it's an anti-orientation. So it's going to be an IR compensatory stretch.

So you're basically training this neural interplay to the muscle to be able to gain a joint position. What's the time element here? Why does time help with that?

Yes. Yes.

I'm looking at the skeleton over here and considering that if someone has a wide ISA bias and consequently a wider infrapubic angle by default, when comparing wide versus narrow ISA structures without compensatory strategies, wouldn't you expect the wide ISA pelvis to be slightly more posteriorly oriented at rest in standing? This is because the flattening nearly brings the pubis forward, suggesting the standing position of the wide ISA pelvis would be slightly more posteriorly oriented by structure alone.

So Frederick, thank you so much for this question. It's going to help a lot of people because this is a fairly common condition in the clinic. I think it's a very small percentage of the total population, but we see a fair amount of this in the clinic, especially with people that do what would be considered extension-based activities like gymnastics would be one that stands out in my mind. So again, thank you for Frederick, if you would like to participate in a 15 minute consultation, please go to askbillharman at gmail.com, put 15 minute consultation in the subject line so we don't delete it. We'll arrange that at our mutual convenience. I will see you tomorrow morning, Thursday, 6 a.m. Coffee and Coaches Conference call. Have an outstanding day.

But yeah, it knows what to do under the circumstances. It's Bill at IFS physical therapy. If you get that pain on the backside of your wrist when you do pushups or get down on all fours, give this a try. Step back on the same side leg, bend forward to about 90 degrees, and then turn your arm inward. Turn your palm outward, and you're going to do a curl right there. Breathe in, hold it, and exhale on the way down. Breathe in, hold it, curl, exhale on the way down. Knock out about 10, 12 reps of that, and then recheck your push-up. We're talking about capturing the early foot. And that would be medial heel contact, first metatarsal head.

I would measure ER with it.

So they are actually creating orientations to produce high levels of force. Because you have two, 300-pound bodies that are pushing against one another. And again, if I don't stay in that downward force position, all I do is get lifted up and I get beat. And then that's where I do have some relative motion to give up. And then that's where I get turned. Right. If you look at a snapshot of alignment and position, you see a lot of 90-degree angles. But these are orientations to allow them to produce maximum force. So they work in a very small range of motion.

I guess I'm recognizing that, but it's also trying to figure out from a conceptual standpoint, trying to get to a point of where my first decision is better. It's still like a test-retest, obviously and even as always.

Yeah.

Yes, so you see the foot slam down into the medial foot contact, but the tibia stays out. Right? You see it? It just goes right up your leg, because I need my ER representation to get me into the position. If I take away that lateral foot contact, then my starting conditions have changed. I'm going to land in middle, but I'm still going to try to stay ER'd. So where do you think the center of gravity is going to want to go as I'm landing in an early propulsive foot?

Right.

Okay, okay. If you can appreciate the frustration, so like every time you feel that, every time that you're challenged by that and you accept the challenge, that's a good thing. If you move away from it, then you probably need to rethink your process and maybe your professional goals a little bit. But if it's like you want to help them or you want to know the answer and you're willing to go dig through all the crap, then you're in the right place. Because it becomes so much more satisfying when you are successful. Satisfying, don't pat yourself on the back. Don't get excited about it. Don't get upset about your failures. Don't get thrilled about your successes. Just recognize them for what they are. But it's the curiosity. Like if you're still curious, if you're still trying to figure things out, it's a good thing.

Okay.
