On this episode, WHOOP Global Head of Human Performance and Principal Scientist, Dr. Kristen Holmes sits down with exercise scientist Dr. Lauren Colenso-Semple for a refreshing, evidence-based conversation that cuts through some common myths in fitness. Together, Dr. Holmes and Dr. Colenso-Semple unpack how social media has fueled misinformation around hormones, menopause, menstrual cycles, strength training, and recovery.
Dr. Colenso-Semple challenges popular narratives around cycle syncing, hormone optimization, and sex-specific training. The episode makes the case that while men and women are biologically different, the fundamental principles of building strength, improving fitness, and maintaining health are remarkably similar. The discussion also explores hormone therapy, hormonal birth control, testosterone, Zone 2 training, and why consistency is the true path to long-term results.
Whether you're new to exercise or a seasoned athlete, this conversation offers practical, empowering advice rooted in high-quality human research rather than hype. If you've ever wondered whether you're "doing it wrong" because of your hormones, this episode will leave you feeling informed, confident, and ready to focus on what actually matters.
