A Year of Strength Training After 50: What Actually Changes

What does one year of strength training after 50 actually do to your body? Two versions of you, the same age, the same year: one lifts two or three short sessions a week, the other does nothing. Twelve months later, the lifter can be around 50% stronger, with better blood sugar control, bones that are being rebuilt instead of quietly thinning, and muscle genes that have shifted back toward a younger pattern. In this video we follow one year of strength training after 50, month by month. We cover what happens in your nerves, muscles, blood sugar, bones, brain and joints, and why the biggest benefit isn't what you gain this year but what you refuse to lose over the next 20.
