Ep 66 - Lauren's Research

A special interview episode: Trexler interviews Lauren about her research at the intersection of exercise, muscle physiology, and women. She explains how she backed into menstrual-cycle research after realizing it was a perceived barrier keeping labs from studying women at all, and why her finding that cycle phase doesn't much affect training adaptations should have opened the door to more research — before the internet "slapped her in the face." They cover which sex differences actually deserve attention (menstrual symptoms, PCOS, endometriosis, pregnancy, postpartum, menopause) versus the over-complication that markets special protocols off single-hormone claims. The heart of the episode is three practical questions — how to train around your menstrual cycle, how to think about hormonal contraceptives, and what to actually do at menopause — with the same nuanced answer each time: track your own response, adjust reactively rather than proactively, and match the tool to the goal.
