Yeah.

So plyometric type work, or if we're looking at not having the robustness of doing straight plyos, then you can do banded-assisted pogos.

You can do low-depth jumps.

You're getting some impact to the bone because, as Dr. Roy was talking about, it's a multidirectional stress exercise.

And people think, oh, I run, I'm going to have strong bones, but running doesn't do it.

You need multidirectional stress.

So if you think about it, when you land, your body has to move, the ground doesn't.

So it's called the ground reaction force that comes up through the bone to create that strength.

So that ideal situation in a workout for her would be some mobility, some heavy lifting.

If we're doing plyo, that's also a sprint-type training, so you're getting a metabolic stress.

So you're hitting all the major factors in one one-hour workout.

Yes.

Yes, you can.

And the other thing that isn't really brought up into these conversations is when you hit perimenopause, not only is estrogen sort of the stimulus for satellite cell or building muscle cell, but it has a distinct function.

I guess, influence on myosin.

So myosin and actin are two contractile proteins.

So if you think about a sliding filament or coming together, you have myosin and actin that bond together to then pull and move and pull and move, and that's how you have a muscle contraction.

Estrogen is responsible for how tightly myosin bonds to actin.

When we start to lose estrogen or we start to have variability in our estrogen, we get myosin dysfunction.

So that means we're not going to get a very strong contraction.
