The Bill Hartman Podcast for The 16% - Season 15 - Number 4 Podcast
Good morning. Happy Monday. I have narrow coffee in hand and it is perfect. All right. Busy Monday coming up. First things, a quick housekeeping item. For those of you at IFS University, we would call it 1 p.m. Eastern Standard Time. If you're not at IFS University, please go to ifesuniversity.com. Get yourself signed up and please join us for that call. Again, 1 p.m. Eastern Standard Time. Digging into today's Q&A, this is with Alex. The initial part of this call was about how we're shifting centers of gravity in specific archetypes, very specifically we're talking about narrow ISA individuals, how we're moving them primarily from right to left in the initial phases of recapturing movement. And the cool thing is the way this question evolved is we got into the reasoning behind the static versus dynamic activities. Ultimately we want all of our activities to be dynamic in nature, but in many cases we have to use a static representation because most folks can't actually produce the shape change that's necessary to capture their normal relative movements. And so, again, I totally appreciate this question from Alex because it allowed us to go someplace that gave us this little bit of understanding that I think a lot of people miss out on as to why you would use certain types of activities. And again, ultimately, we want to be moving people towards the dynamic element because that's where movement really exists for us. So, thank you, Alex, for your question. I'm going to guide and help a lot of people. I'll see you, folks, on I-Fashion University this afternoon. Everybody have a great day. I'll see you tomorrow.

Okay. So, I have a question about pushing right to left for an arrow. Is it fair to say that, to do this effectively, we need to bias pressure toward the first met head with an orientation of an anterior pelvic outlet, so water flows out and forward on the left.

And then- You talking about the right side? The left side. Okay. So we're going that way? Right to left. Okay. I'm with you. And then just by pushing off the right side, and reloading it and move the center mass to the left, that allows the right side to achieve the orientation. That allows the left side to come down lower than it.

The left side. Right to left. Okay. I'm with you. And then just by pushing off the right side, and reloading it and move the center mass to the left, that allows the right side to achieve the orientation. That allows the left side to come down lower than it.

Okay. So we're going that way?

Right to left. I'm with you. By pushing off the right side, reloading it and moving the center mass to the left, that allows the right side to achieve the orientation. That allows the left side to come down lower than it.

Okay, so you're going to be shooting for an early representation, right?

On the right.

Early representation on the right is going to stick you on the right.

Right. So I have to move that way, right? So I have to push into the ground here. That's going to take the outlet up. It's going to tip the outlet down into the left, isn't it?

Can you say that again a little slower? Please.
So if I'm pushing right to left, I have to push out of the cut on the right hand side. I went into the cut, which means the outlet had to move in the direction that I was going. So I get orientation into the cut. That's an expansion down and forward into the cut for me to push out of the cut to move right to left. I have to push the outlet back up and it's going to make the other outlet lower.

Okay. Do you understand? Yeah. I think so. Um, eccentric overcome, eccentric yield. Do you understand? Yes.

So this one's going up. This one has a delay in it. This one's going faster in this direction. This one's not going as fast in the same direction. Therefore everything goes in that direction.

You see it? Yeah.
So the second part of my question is to optimally push off of the right side. I've been playing around with two ways to do it. One is to just keep the right foot on the ground and push off the whole edge of the foot like a skating blade. The other is to, like in a sled drag, you roll from the heel to the toe. What's the difference between the two?

Is that what you're asking?
Yeah.
Okay. What's the difference between the two?

With the ladder drill, the heel to toe contact occurs later because you'll pick up more from the first metatarsal head.

Which one takes longer? The ice skating blade.

Okay. So less foot contact. There's no roll into it, right? There's no roll into it. Yeah, but you're stuck in the middle the whole time.

There's no role into it, right? There's no role into it.
Yeah, but you're stuck in middle the whole time. Relatively.
