For men, I think you have a better bandwidth of when you should start implementing.

So I am notorious for slamming things like Orange Theory and F45 because they market specifically to that age group of women. And it's not appropriate because it's not true high intensity work.

When we're looking at women who are really trying to maximize body composition change and longevity and unfortunately default to cardio because they think, oh, that's going to help change my body composition. It's going to help me lose body fat. It doesn't.

Yes, there is. But it puts women squarely in moderate intensity where they're so used to leaving one of those classes feeling absolutely smashed.

that when you tell them, actually that training doesn't work for you because it's putting you in a state of intensity that drives cortisol up, but it's not a strong enough stress to invoke the post-exercise growth hormone and testosterone responses that we want to dampen that cortisol. So this is why we have that hyperbole of women who are in their 40s plus shouldn't do high-intensity work.

It's like, well, actually they shouldn't do moderate intensity. They need to avoid that. Polarizing, absolutely. That's what we want. We want true high-intensity work, which is one to four minutes of 80% or more. Or if you're doing sprint interval, it's full gas for 30 seconds or less. And you're doing that a couple of times a week.

You're not doing it every day because you need to have enough recovery to hit those intensities truly because those are the intensities that are going to give you those post-exercise hormonal responses to drop cortisol. When we're looking at women who are like, oh, well, I love going out for hours and hours on my bike and I love doing my spin classes.
