In this episode, Laurel and Sarah sit down with muscle physiology researcher and science communicator Lauren Colenso-Semple to take a hard look at some of the most popular and problematic claims circulating in women’s health and fitness. Together, they unpack the slogan “women are not small men,” and the idea that women need completely different training and nutrition approaches than men. Lauren explains where the evidence actually stands on topics like muscle loss at 30, lifting to failure, cardio recommendations for women, bone density changes at menopause, training fasted versus fed, cycle syncing, cortisol “hacks,” and more.
This conversation is a deep dive into separating women’s physiology from marketing ploys. Learn why overcomplicating women’s training does more harm than good. You’ll gain clear, evidence-based guidance for women in perimenopause, post-menopause, and beyond.
