And so we have to have some form of key performance indicator that is going to allow us to determine whether we're on the right path or not. So if I'm trying to improve someone's acceleration, so let's say that I'm measuring their acceleration through a 10 meter sprint from a standing start, I take them into the gym, I train them, I bring them back, and I retest that 10 meter sprint. And if that continues to improve, then my strategy in the weight room is good. And so if I'm using bilateral symmetrical activities to do that, great. But at some point in time, and maybe it happens and maybe it doesn't, at some point in time, it can become interference. The only way that you can tell whether this is going to happen is as you train them. And again, this is why we monitor key performance. Friday. So this comes from Jason and Jason says, it's common sentiment that we hear in the industry that a certain muscle is tight because it's weak, particularly in reference to hamstrings, hip flexors, and shoulder extra rotators. How does this concept fit within the orientations and strategies of your model? Well, let's talk a little bit about the concept that you're asking about first and foremost and let's kind of figure out where that sort of comes from. And I think it's based on what would be the typical structural reductionist model where people are taking physical properties in the world around us and then trying to apply them to humans. For instance, if you pull on a rope or stretch a leather belt or a rubber band, you feel the tension. And if your model of the world is based on these physical properties and you apply them to humans, then my perceptions are going to follow. And so it's like we compare muscles to tension in rubber bands, even though that's not remotely true. That might be where this kind of thing comes from. Nuts and muscles is another one that stands out in my mind. Muscles don't actually have nuts in them. They might have contracted areas that become sensitive, but somebody called them nuts at some point in time. It caught on. It's great metaphor. It's very useful for a descriptor to describe a sensation. It's just not much of reality. Doesn't mean we don't feel tension in tissues. So under circumstances of yielding actions, we certainly do feel that because load is always distributed into the connector tissues and that's a lot of what we perceive based on my model. So whether we have a concentric or an muscle or an eccentrically oriented muscle, and we get to some end of excursion that is allowed under those circumstances and we do have the yielding action. That's definitely what we're going to feel.
