A lot of women come with their partners to see me and say, I don't understand. We're both doing the same training. He's leaning up and getting fitter. I'm putting weight on and getting slower. And that is because we have puberty. We have our reproductive years. We don't have pregnancy in there. We have perimenopause. We have postmenopause and menstrual cycle.

Each one of those is a different hormone profile that can affect the way we eat and the way we train. But no one told us this or what we can do.

Whose best-selling books and over 100 peer-reviewed studies is revolutionizing how women can optimize their health, fitness, and longevity by working with their unique physiology.

We're looking at sports science research. Everything from training to eating, recovery, it's based on male data. And women have been generalized to that data. Things like we see men do really well on calorie restriction and fasting. But for women, it doesn't happen that way. and we'll talk about that.

And we also know that during puberty, girls' hips widen, shoulders widen, which changes our angle of the native hip, what we call the Q angle, so they don't feel comfortable running or swimming or jumping. And because they're not taught this stuff, we see that by the age of 14, girls who previously were sporty, over 60% of them drop out of sport.

The problem is, it's never about how we can empower women to use their physiology to their advantage.

I look at sex differences in exercise and nutrition because when we think about everything that we know for protocols from training to eating, recovery, it's based on male data. And as a female athlete. And working with women across all ages, just trying to maximize their potential, you have to lean into different data. But people aren't aware of it.

So as I'm looking at what I do and trying to empower women to understand their own bodies, realize that there's a lot of research that still needs to be done. So if we think about something... like caffeine and caffeine intake, right? And people are talking about how it either boosts them or not.

If we look at all the data on performance about caffeine enhancing performance, there isn't anything that's been done on women. So if we're looking at How does that work for a woman? We have to look and say, okay, how much exercise have you done? Where are you using caffeine? When are you using it? Because we fuel differently during exercise. We go through blood sugar quickly.
