The idea
Muscle mass declines about three to eight percent per decade after thirty, accelerating after sixty, yet resistance training raises strength even in the nineties.
In practice
A ninety-two-year-old lifting light weights twice a week and climbing stairs more easily months later.
Where people slip
The misconception is that muscle loss in old age can't be reversed; strength responds to training at any age.
