Many of our older population are physically 20 years older than they are chronologically. Physiologically, there is no reason why people need to slow down as they age. The good news is that the body can bounce back from inactivity. The weight training is particularly important as it helps maintain bone density. Taking calcium or estrogen supplements is not enough.
Bones get thicker only when they are used.
Besides the physical benefits of greater energy and body coordination, working out allows seniors a glimpse of the tremendous physical and mental potential they still possess.
