If you’re not musclemaxxing, now is the time to start. Sarcopenia starts around 40. You lose roughly 8% of your muscle per decade until about 70, and around 15% per decade after that. (In the video I’m doing a pull down with my actual body weight) Before perimenopause, muscle holds steady in most cases. Through the transition it flips, and after menopause it falls about 0.6% a year while fat gain nearly doubles. We also start 30 to 35% behind men in absolute muscle mass. The transition widens a gap that was already there. So the stake is whether you can get off the floor unaided at eighty, whether your blood sugar stays in range, and whether your bones become brittle.
