This mental model highlights how hormonal changes after the age of 40 impact muscle building capabilities.
As we age, especially after 40, hormonal changes play a crucial role in muscle building. Testosterone levels decline in men, which can lead to reduced muscle mass and strength. In women, after menopause, estrogen levels drop, impacting muscle repair and growth. Growth hormone and insulin-like growth factor (IGF-1) also decrease with age, further hindering muscle development. Understanding these hormonal shifts is essential for developing effective training and nutrition strategies to maintain and build muscle despite these changes.
Age is no barrier. It's a limitation you put on your own mind.
