The Bill Hartman Podcast for The 16% Season 9 Number 5 Podcast
But it's just like taking a step forward, my friend. Good morning. Happy Monday. I have no coffee in hand, and it is perfect. All right. A busy Monday. Quick housekeeping. iFashion University members. The Q&A from last week is posted and ready for your viewing. If you're not a member of iFashion University, you can go to ifashionuniversity.com and get signed up there. I'm going to dig right into today's Q&A. This is with Misha. Misha has some questions about rolling. One of the things you want to recognize about rolling, it is a form of propulsion. So it's going to follow the same rules. So we have the shape change. We have yielding actions that create delays. We have overcoming actions that create the advancement. We have an early, a middle, and a late representation. Keep in mind that when we're rolling, we're rolling the axial skeleton. So pay attention to what the axial skeleton is doing. Try not to get distracted by the extremities as many people do when we talk about things like walking as well. But so remember, rolling is propulsion. Okay. If you would like to participate in a 15 minute consultation, please go to askbillhartmanedgymail.com and put '15 minutes consultation' in the subject line. And we'll arrange that at our mutual convenience. Everyone have an outstanding Monday. I will see you tomorrow.

Go ahead. Fire away. So first question: When you initiate a roll to the left, the first thing you need to do is to compress on the left side so you can fall to the left.
rollingpropulsionshape change
Correct. So you're actually creating a shape that creates a downhill force, so to speak, for the internal organs to fall down and to the left to initiate the force in that direction.
propulsionshape changerolling mechanics
Yes, that is correct. So you have to have a somewhat over compression on the left side so there will be expansion on the right.
rollingshape changepropulsion
That is correct. So if you look at the cross-sectional shape of the thorax as the roll initiates, the left side goes flat and that actually makes the right side, if you're looking at it from ground level, slightly higher. That creates this downward gradient towards the left side that gets everything moving in that direction. It's very quick, but it does happen.

Okay. So in the past, you talked about how sometimes if you want to roll somebody to the left, first you need to teach them how to do like the overcoming strategy on the left side. That creates the shape.

So that creates the shape, right? And as you would be reaching forward with your left side, the left shoulder is moving away from the floor, but the shape that creates is the shape that falls back down to the floor and initiates the roll to the left. Does that make sense?
rib mechanicsthoracic shape changerolling mechanics
Yes. So most likely, if someone cannot create that shape change, it will be somebody who is very late on both sides. So those are the people that you say you need to bring them back on the right side first. So those are the same people, yeah?

Yes, sir. You got it. That's exactly right. That's exactly right.
And I have a lot of trouble with people like that. Don't we all?
We all do. We all do, my friend.
But you see, I cannot touch people. I understand. So from an activity standpoint, would this be so you're trying to create some kind of overcoming on the left and you're trying to create some space on the right side? So, for example, this would be like a supine cross connect with the right foot on the wall. Then you're reaching with the left hand and you're staying left side heavy.
supine cross connectovercomingside heavymotor control
Well, wait a minute. Okay. So, think under this circumstance, you're actually going to have a compensatory ER representation on that left side. So we're late on both sides. And you're trying to move them back on the right. So you're actually trying to create the expansion posteriorly on the right. And so what you're going to have is you're going to have an ER representation as they're bringing that left knee upward. So you get the right foot on the wall. So you push on the wall, bring the left knee up. You're actually using the compensatory strategy on that left side to help you create the delay on the right side to bring them straight back on the right.

Okay, so in that case you might want to maintain like right heavy.
weight distributionmotor controlpostural strategies
Here's what I would suggest. Use the foot contacts on the wall to drive that representation. Rather than saying right side heavy, I would say make sure you hang on to those right foot contacts. Here's why. If I use a compensatory strategy on the left side to try to create the right posterior expansion, the minute I lose that right foot contact, I am just orienting everything in that direction. What I want to do is I want to create a turn inside of that foot contact. So the medial foot on the wall, I want to make sure I hang onto that and I want to hang onto that because if I roll to the outside, I no longer have the ability to create the right posterior expansion. So I would emphasize the foot contact more so than the heaviness under this circumstance.
compensatory strategiesfoot contactsposterior expansionlateral orientation
Okay, and in that case, you would have the right foot on the wall, you're reaching with the left knee towards your left eye, and you're reaching with the right elbow across the body.

Yes, sir.
Yes, sir. Okay.
But then, because I'm using the compensatory strategy on the left side to help me create the right side shape.
compensatory strategiesmovement patternsbiomechanics
And then after you do that, you can do the left cross connect. And then in this case, you'll be creating the first shape that you need to initiate the roll. By reaching with the left. I think I understand.
movement initiationcross connectshape creation
I understand.
And another question. This is something that I also have some trouble with. If you're initiating a roll with a lower extremity, and your leg is relatively straight—so you're just doing it, let's say, going from right to left. In your video on rolling, you said that you're going to have a yielding strategy on the right side. Correct. Which is confusing to me because the right side is moving forward, the left side is staying back.

At what point are you talking about it? Because that's what matters. So if I am on my side and initiating the roll, the shape of the axial skeleton is still an early representation. It doesn't mean that there's no late coming. It just means that as I'm on my side and initiating that roll, there is the early representation of that as the leg goes across. Because the leg is moving faster than the pelvis is. So the pelvis is moving slower. How does it move slower than the leg? I have to create the delay, don't I? As you step over with the leg, and so we're rolling left to right, as I step over with the leg, and then the foot makes contact with the ground, the foot stops moving, and then the pelvis starts to move, and then I'm creating the overcoming against the sacrum to create the turn. Now the delay drops from the top hip to the bottom hip, because I have to slow down the downside, because it's stuck to the ground. So you have to look at where you are in the roll to identify what strategy you're talking about.

Okay, so if you're just in supine and you're reaching with the right leg across your body and the pelvis hasn't started to move yet.
rolling strategypelvis mechanicslimb movement sequencing
Okay, start on your side.
Okay.
You're on your left side. Right leg behind the left leg. Pick up your right foot and move it in front of the left foot. The pelvis didn't move. That means the pelvis is staying back and the foot is moving forward. Correct? For one thing to move faster than another, there has to be a delay in the part that's not moving as much. You're holding that side back. Holding that side back is a delay strategy, which means that is the early representation. As the left foot comes across and makes contact with the ground, that foot is now slowing down, but the pelvis is still going to move through space, which means the pelvis is now moving faster than the foot. Which means I went from a yield to middle to overcome on the top hip. On the bottom hip, I am now creating the delay strategy on the bottom as I transition to overcome on the top hip, because the top hip is now moving faster than the bottom hip.

Yes. So can we talk about where the delay strategies would happen, like upper or lower? So let's just say I'm on my side.
