If you are looking at cardiovascular and you want that big sweat, then we are talking true sprint interval training. So what I have a lot of women do is a 20-minute lower body heavy set, and then they'll go on the assault bike and do as hard as they can for 30 seconds and then recover as much as they need to to go then do another 30 seconds as hard as they can.

Most people go, oh, I can do four or five of those. After two, they're completely gassed. because it's that hard of work. And that's what I mean by polarizing. You have very, very low intensity for recovery and super, super high intensity for metabolic and cardiovascular changes is what we're after.

So this is the sticky point of recent science because we see all these research studies and meta-analyses that are coming out of the sports science literature saying that there is no effect of the menstrual cycle on anything. When you look at that population, it is specifically eumenorrheic women might have a subject pool of 10, if you're lucky, 12.

Supposedly ovulating. So they have a definitive low hormone and high hormone phase.

Yes, exactly.

Right. Okay. And they look at performance, meaning that one point in time. And we know that psychologically you can perform at any point. in the menstrual cycle unless you have something like heavy menstrual bleeding.

When we're looking at a higher touch and looking not only from a molecular aspect but also pulling in mixed methods and looking at the qualitative, we need women to track their own cycle and find their own patterns because we know that there are times where you feel like crap and you can't push intensity. but that might be on day eight for one woman, it might be day 18 for another.
