And so like something like jumping rope is really important, right?

Your feet are just kind of moving like that.

They're acting as shock absorbers.

Calves and Achilles have to constantly change in length.

And that accommodation is a really important part of resilience.

And I think that should be an important part of everybody's warmup at a minimum, if not part of their workout.

Well, I mean, I think, look, muscle mass...

is probably the second most highly correlated finding or third most to longevity after strength and cardiorespiratory fitness, VO2 max.

So why is that?

So first of all, I think that muscle mass is both directly a proxy for strength.

In general, the more muscle you have, the stronger you are.

We all know exceptions to that.

We know wiry little people who are insanely strong.

And I have patients like that.

They're just naturally thin people.

But when we put them through the testing protocols,

You know, they're remarkable in terms of their strength.

And I tend to not worry about the fact that they're slight in build when I see that they're strong across the board.

There is another benefit of muscle mass, which is it's the place where you dispose of glucose.

So from a metabolic perspective, the more muscle mass you have, the more glucose buffering capacity you have.
