Episode 435: Dr. Stacy Sims: Workout Like a Woman Not a "Little Man" + How To Train Based on Hormones
25 Mar 2025
Ever wonder why your fitness routine doesn't yield the same results as your male workout partner's? In this episode on the Habits and Hustle podcast, I talk with exercise physiologist and nutrition scientist Dr. Stacy Sims, as she reveals that women's bodies respond completely differently to exercise due to our unique physiology. We dive into the importance of tailored training protocols for women, especially during different life stages such as puberty, perimenopause, and menopause. We also discuss essential supplements, the implications of using Ozempic for weight loss, the benefits of exercise over pharmaceutical interventions, and underrated health tips. Dr. Stacy Sims is a forward-thinking exercise physiologist and nutrition scientist with an MSc and PhD who specializes in female-specific training, nutrition, and health. Named one of the top visionaries in the running industry and featured as one of the top women changing the paradigm of her field by Outside Magazine, she is the author of the groundbreaking book ROAR and creator of the "Women Are Not Small Men" philosophy. Dr. Sims has published over 100 peer-reviewed papers, directed research programs at Stanford, AUT University, and the University of Waikato, and continues to advocate for women's health through her courses, speaking engagements, and research.

Dr. Stacey Sims, I want you to know that I've been a fan of your work for, I just said this earlier, but for years, because I saw your TED Talk on basically how women are not these little men. And, you know, the fact that you've been out there, like you said, talking about women and how women are not like men and they shouldn't be training like men and blah, blah.
I want you to kind of talk from your words, like what you do and why it's so important.
Yeah. So I started as an athlete and an academic and an academic in sports science and nutrition. And all the things that we are learning in class didn't really apply to me as an athlete or my teammates. So that really started the question of what are we doing? And as you started digging in, realizing that there really wasn't very much research on women.
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.
