Somebody not realizing that one side is aimed at another direction than the other side.

So simply letting people know that their joint is not supposed to be doing that, that's not a proper pattern, is a critical component.

So from the onset, and again, we can maybe have further discussions about this in future episodes, moving well needs to have those four components at each joint throughout our body.

If we can do that, we can set aside the injury risk and stuff, and again, talk about that later, and we can move on to really performance.

Now, when I'm asking about a muscle or muscle groups to perform, I care about three things.

Can it be fast?

Can it be strong?

And can it have what's called muscular endurance?

This can be expressed over a concentric muscle action, an eccentric, or an isometric.

So generally, when we say concentric, we're thinking about shortening of the muscle length.

So imagine doing a biceps curl.

When you're actually taking the dumbbell and moving it closer towards your shoulder or your face, that muscle or muscle group is shortening.

That'd be the concentric portion.

If you got all the way to the top or say halfway up or any range part of the range of motion and you stop the movement and held it there, that'd be isometric.

And then if you lengthened it back down all the way to the bottom, that would be the eccentric portion of it.

And so I want you to have the ability to be fast in any of those ranges of motion or any of those muscle actions.

I want it to be able to be strong in any of those muscle actions.

And then I want it to have the ability to repeat that multiple times.

This could mean repeating holding the position.

So if I could go to, say, halfway up, I could flex and hold it there.
