And even when you're looking at the textbooks and textbook pictures of representation, they're all male, male bodies. So that was so many decades ago. And ever since then, I've been really trying to dig into both research and the application of research to get women to understand that their bodies are different. We have different physiology from birth. We have hormone fluctuations.

And these affect every system of the body. And we respond to training differently than men. We respond to stress differently than men. And the more we dig into it, the more we realize there's a lot of research to be done. So the research that we do have, I'm really adamant about getting it out so women can be empowered to understand what is going on.

Because face it, we put as much work into our training and we take time out of our day to really work on our health and well-being. So it should be appropriate for us. We shouldn't be fighting the battle against our own bodies because of protocols based on male data.

So that's my mission across the lifespan is to get women from puberty all the way through postmenopause up to speed about what their bodies are doing and how they can modify or alter what they're doing to get the best benefits.

Yeah, for sure. I like to kind of start this conversation when we look at the sex differences that exist at birth. So that's like without our hormone fluctuations from our menstrual cycle and stuff. So when we look at XX versus XY, because that's the primary area of research that we have. Very binary, but that's all we have at the moment.

If you are born XX, then you have more endurant type fibers. So your slow twitch, your oxidative, very aerobic type fibers. And with that comes a lot of mitochondria work. So that means your body's really able to take fatty acids and use it, use oxygen and go long and slow.

When we look at XY, they're born with more of the fast-twitch glycolytic power-based fibers, so good at speed, good at quick reaction time, good at doing super high-intensity work, and they have to work on developing that aerobic system.

So as we feed forward and see at the onset of puberty what happens is there's another divergence where with what we call the epigenetic exposure or the situational change that happens with estrogen, progesterone, to some extent testosterone in girls, we have a change in all of our biomechanics. So our center of gravity goes from being up in the chest area down to the hip area.
