So as a physiologist, I'm going to explain what's happening on the undercurrent of everything. So we look at estrogen, progesterone, and testosterone, and they affect every system of the body.

So when we start losing the higher doses and pulses of estrogen, and we have more and more anovulatory cycles, so we don't necessarily produce progesterone, every system gets affected, specifically bone and muscle. So we'll have women who are complaining about waking up feeling squishy overnight and they can't even open like the jar of pickles because they don't have the strength.

And they're like, what's happened? That's an estrogen effect. Because when you look at how estrogen affects skeletal muscle and the feedback mechanism for strength and power development, it's in every part. It's on the satellite cell to develop more muscle fibers. It's on the nerve endings to be able to say, yep, let's create a really fast nerve conduction mechanism.

across the gap junction to be able to fire a lot of fibers to create a strong contraction. And it's also part of the contractile proteins itself to be able to grab together to create a strong contraction. So when you lose estrogen, you're losing the impetus for those three main points of strength and lean mass development. So when I start explaining this, people are like, shit, now what do I do?

It's like, okay, well, now we want to look at a nervous system response. Because if we can find an external stress that's going to create the same cascade feedback mechanisms that estrogen did, then we can keep progressing. And that is strength training. But it's not lightweight, going to failure type stuff.

We have to take a page out of the power-based work where we're looking at zero to six reps. We're doing heavy loads. We have lots of recovery between those loads because we're trying to really stimulate the central nervous system and peripheral nervous system to say, you know what?

I've got to have a lot of muscle fibers and I need to be able to recruit them quickly to have a very strong contraction to withstand that stress and load. So now we can build lean mass, strength and power without estrogen.
