It’s never too late to build muscle and strength.

Research shows muscle loss happens about 5 times faster than muscle gain. One study found just 2 weeks of limb immobilization caused 3–9% muscle loss, which was similar to the 4–8% muscle gain seen after 10 weeks of resistance training in young men. Which means rebuilding is much harder than building in the first place. While it’s never too late to break this cycle, the reality is it’s easier when you take earlier action.
