But the length of those classes and the speed at which those movements are done is really a precursor for injury with how fast the movements are underweight. And you can't really recover well enough to hit that 80 plus percent for your interval. Because if you're looking at a 45 to an hour long class, you cannot hold high intensity for that long. That puts you in moderate intensity.

Now, the problem with moderate intensity is our bodies, when we're perimenopausal, are already under a significant amount of sympathetic stress. So this means we're tired but wired. We have a really difficult time coming down from that anxiety and that boredom. awakeness, flight or fight sensation, and moderate intensity perpetuates that.

When we look at what it does from a metabolic standpoint, it doesn't have a post-exercise response that true high intensity does of increasing growth hormone and testosterone that drops cortisol. So when we're doing this moderate intensity stuff, we end up with a higher circulating amount of cortisol, which becomes our new baseline. And we don't get any of the metabolic change.

We're not going to see a dissipation of our minnow bellies or visceral fat. We're going to see an increase in that. We're going to be completely tired all the time, which means we are not sleeping well. And if you can't sleep well, you're not going to invoke any change. So when we're looking at that moderate intensity work that people feel is high intensity, I feel like it's such a disservice.

And what makes me angry about these classes is that they are really marketing to women 40 plus. And I'm like, this is just not appropriate. These women are coming, wanting help. They want to do some strength training. And the protocols you're throwing in there are specific for men. And you're not looking at what's happening when women hit 40 onwards. So when we talk about true high intensity,

So when we talk about true high intensity,

We look at taking a page out of High Rocks or CrossFit where they're doing every minute on the minute for four minutes and then one minute full recovery. And you might do two or three rounds of that. And that is true high intensity work because each minute you're going to go as hard as you can. It might be 40 or 50 seconds, 20 seconds to get to the next one.

Then you do that four times in a full minute to like come down. Maybe it's two minutes to come down. Repeat that again and maybe a third time. So all up, it's 20 minutes of work. And that is true high intensity work.
