Female physiology reshapes strength training
Women’s training often changes when hormones, recovery, thermoregulation, sleep, and body composition shift. Sims explains sex-specific considerations in fueling, hydration, menstrual cycles, pregnancy, and menopause while challenging programs built from male research. Strength training becomes especially important for muscle, bone, power, and future independence, but intensity and recovery still need individual adjustment. During a period of bodily and social change, the book offers practical agency without promising that one protocol fits every body. Use physiology as information, not destiny; combine evidence with symptoms, medical context, and lived response. Training should increase capacity and confidence rather than become another punishment for aging.
