Good morning. Happy Tuesday. I have neuro coffee in hand and it is perfect. All right. A busy Tuesday coming up. We're going to dig straight into this Q&A. This is with Brian. Brian works with a lot of golfers in this discussion, which sort of revolved around capturing very specific positions through the golf swing and then the influence of pressing activity specifically overhead pressing with golfers as potential interference to these positions. And so this just lends itself to the fact that we have to understand the secondary consequences of the exercises that we select and how we program as to whether we're enhancing the capabilities that we're trying to influence or whether we're interfering with them. In many cases, too much force production for too long a period of time can be interference in some of these activities that require the demonstration of velocity. Or if we prolong a position, we then create potential interference to that velocity. So gains in force production are not always favorable. So thank you, Brian, for asking such a good question. Probably going to be useful for a lot of people. Everybody have an outstanding Tuesday and I will see you tomorrow.

Okay, so continuation kind of a pause line, I thought, but you know where I'm gonna take this, right? I'm taking it to the golf swing.

Bill Hartman 1:32–1:36
Oh, okay. I would be shocked and amazed if we didn't talk about golf, young man.

SPEAKER_03 1:37–2:06
So with the reaching versus the hard style press, I'm thinking in the golf swing, with max P at the top and then left arm parallel and transition, essentially, we've got a middle piece gap position, right, in those scenarios during that timing of the swing.

Bill Hartman 2:07–2:16
Yeah, so everything is going to compress anterior to posterior at the, keep in mind it's a twist, right? You understand that we're turning?

SPEAKER_03 2:16–2:17

Bill Hartman 2:17–2:55
Okay, so look at it from the foot perspective. If I step forward with my right foot, the sequence is early pronation, going through middle, maximum pronation, late external rotation. Then the other foot lands and that sequence is early, middle, maximum pronation, late. As I'm turning, I'm creating that strategy on one side, and as I turn in the other direction, I have to create that strategy on the other side.

SPEAKER_03 2:55–2:56
Yep.
Bill Hartman 2:56–3:19
So just so we're clear, we don't turn this into a symmetrical representation until it needs to be a symmetrical representation, which is from that parallel point to impact. Even then, it wouldn't be symmetrical if you're like a narrow ISA kind of guy. And you've seen that a million times where you'll see the guys kind of over one leg as their impact. And you see the other guys that are kind of square to the ball when they're at impact.

SPEAKER_03 3:20–3:20
Yes.
Bill Hartman 3:20–3:20
Yeah.
SPEAKER_03 3:22–3:35
So I'm thinking from a standpoint of okay, to maintain that differential from left to right, like a lot of the pressing activities, they just create a ton of interference, right? So a golfer in my mind would be, in most cases, better off working on a unilateral like a lighter resistance activity, so they maintain that differential.

Bill Hartman 3:54–4:02
Well, what's the goal? It's real simple because you kind of said it. If the goal is to maintain the ability to create the differential, then the maximum load would interfere with that. But what if I'm trying to increase the peak force output at the turnaround?

Okay, but with a narrow, that would be a pulse of IR, I'd want, again, versus a wide, where I have a longer IR, correct?

Bill Hartman 4:33–5:11
I love the way you're thinking. And when you say the word pulse like that, that makes me smile all over the place because that's exactly the strategy that we want to think about. So think about, like, you could have the right intention and then the execution is incorrect because instead of keeping the force output within that small window of opportunity, you expand that. And now you created, instead of having the relative motion turn and then the quick impulse of the turnaround, you went, squeeze, squeeze, squeeze, squeeze, squeeze, squeeze, squeeze, and then a release and then it's slow.

In that scenario, you create a case where you have to start using orientations to create a term.

Bill Hartman 5:19–5:25
Well, you have to because you couldn't release the tension fast enough to create relative motions anymore, right?

Yep. You see it? Your honorable intentions had the right idea. Just the execution in context was incorrect. So the result that you got created interference instead of supporting the desired outcome.

Good morning. Happy Monday. I have neural coffee in hand and It is perfect. All right. We are back at it after a little bit of a rest over the weekend with the holiday. A quick housekeeping item, IFAST University members. We have called today at 1 p.m. Eastern Standard Time. If you are not on IFAST University, please go to IFASTUniversity.com. Get yourself signed up and please join us for that call at 1 p.m. Eastern Standard Time. Digging straight into today's Q&A, though, this is with Annette. Annette is fairly new to the Coffee Coaches Conference call and to the model, so she asked a foundational question about yielding inside what interferes with our yielding capabilities. What yield is the expanded representation of connected tissue behavior so anything that would interfere with that that doesn't allow us to achieve a gradient of the yielding representation and the overcoming representation of connected tissues will create interference so anything that would be associated with a learned behavior that would create a compressive strategy so anything any of our compensatory strategies that we would see superficially, concentric orientation of musculature, et cetera, that would keep or maintain tension on these connected tissues and not allow that gradient to occur will interfere with yielding. And so we covered that. This is also influenced by the water content of the tissue. So as we age and dehydrate, we tend to see a loss of this yielding capability. We'll see this in tenonopathy as well. So there's a number of representations that we may see where yielding is interfered with. And if we can appreciate this, I think we can be a little bit more effective with our treatment strategies and some of our training strategies. And we actually covered that a little bit at the end of the conversation. Nat's got a background in martial arts, and so we talked about how we can actually use that as a favorable influence to restoring or maintaining our yielding capabilities. So thank you, Nat, for your question. Everybody have an outstanding Monday, and I'll see you tomorrow.

SPEAKER_00 7:52–9:28
I have some general questions about the yielding representation. Since we live in a culture that promotes more concentric and faster movements, more contractions in the body, I feel I'm losing my yielding capability. I wanted to ask how to promote this quality of yielding in movement, or to be more accurate, how to pinpoint the resistance in the body that blocks the ability to yield. In relationship to this question, I also wanted to ask if the yielding representation is always against a support, and if this support has to be the ground or gravity, or if it can be yielding against other areas in the body, like against other tissues or the skeleton.

Bill Hartman 9:30–11:47
So, no matter what movement you're making, you can create a yield by creating a compressive strategy as long as you have the yielding capability. If you have a learned behavior creating a compressive strategy on the front and backside of the body at the same time, you get squeezed between them. One of the goals when restoring relative motion is to produce these compressive strategies while also creating the shape that allows the yield to occur. This is why superimposing breathing on top of things is helpful because the air follows the path of least resistance and allows shape changes to occur. You mentioned ground contact has a lot to do with yielding because that's how we create the potential energy we use to move through space. We take the ground contact, absorb the energy into the tissues, which is the expanded representation of connective tissue—the yield. The yield represents potential energy, like pulling back a rubber band, expanding a balloon, or pushing down on a trampoline. When you push down on the trampoline, it expands and throws you back up in the other direction—that's what we're trying to produce with connective tissues. You can produce this within yourself, but in cases where someone in rehab has had pain-related issues or an athlete has restricted movement, they may have such a strong behavior that they can't produce the gradient between the compressed and expanded representations. That's where manual therapies, ground contacts, and leading resistances come into play because we can use resistance to create compression in one space and expansion in another. The goal is to create the gradient between the two because movement requires a gradient. If we take away your entire gradient, you can't move at all.

SPEAKER_00 11:49–11:50
That's true. Yeah.
Bill Hartman 11:50–12:51
Okay. And so, all of the things that you mentioned are possible. It just depends on the context and the circumstance and the individual. It depends on what learned behaviors they have. What capacity do they have? As we get older, our connective tissues dehydrate. Well, connective tissue behavior is dependent on water behavior. If we don't have enough water content in those tissues, we have given up part of that yielding capability. And so you do the best that you can under those circumstances. You make sure that whatever capabilities that you have are intact. This is where some of the nutritional stuff comes into play. We don't talk about that too much because it's kind of all over the place as far as nutrition goes. But just making sure that you're hydrated so you can move might be useful.

SPEAKER_00 12:52–13:15
Yeah, actually, I refer to this direction. What can we do in our daily life to promote an environment that encourages the yielding? And also, what is the difference between yielding, true yielding, and collapsing into ourselves?
