Let's say that lifting your 50-pound child takes every bit of strength you have. After undergoing three months of weight training you develop the necessary strength so that now you are able to lift your 75-pound nephew. This strength increase can make many functions in everyday life easier to perform. As we age, the maintenance of or improvement in functional strength becomes crucially important. A strong musculoskeletal system will help prevent injury.
Muscles act as shock absorbers for the joints of the body.
All of these factors are of great benefit in helping to prevent injuries. Muscle strength can enhance your physical appearance. I'm not suggesting that weight training will transform you into a Mr. America or a Vogue model. Strength training helps in disease prevention. It greatly reduces loss of bone mass, thus helping to deter the possible onset of osteoporosis.
