Menopause Hormone Therapy and Training: What MHT Can and Cannot Do for Body Composition

Sims emphasizes that the goal of MHT is to attenuate vasomotor and other symptoms, not to mimic the anabolic environment of higher endogenous estrogen. Because the estradiol levels achieved are relatively low, they do not drive significant muscle protein synthesis or bone remodeling on their own. Therefore, the training principles for postmenopausal women—whether on MHT or not—remain identical: heavy strength training for lean mass, impact and jump training for bone density, and high-intensity intervals for cardiovascular and brain health. She notes that MHT does help with bone density and slows visceral fat gain via anti-inflammatory effects, but these benefits can also be achieved with omega-3 supplementation. The key message is that there is 'no free lunch'—pharmacological support does not replace the mechanical and metabolic stimulus of exercise.

Sims explains that the physiological changes of perimenopause—declining estrogen, increasing visceral fat, loss of lean mass—begin years before the final menstrual period. The training shifts she advocates (jump training, heavy strength work, high-intensity intervals) are not just for managing current symptoms like hot flashes or mood swings; they are an investment in postmenopausal health. By building peak bone mass and lean mass during this window, women can better withstand the accelerated losses that occur after menopause. She stresses that the same training components are then maintained into postmenopause, but the starting point and the urgency differ. Waiting until after menopause to begin these practices means missing the opportunity to maximally attenuate the trajectory of decline.
