Weight Lifting Benefits Everyone
Almost everyone should lift weights. Weight lifting strengthens
bones, muscles ligaments and tendons, increases coordination for
tasks requiring strength, and gives confidence and mobility to
disabled people. Just exercising doesn't do much to strengthen
muscles. If it did, marathon runners would have the largest
muscles. To become strong, you have to exercise your muscles
against progressively greater resistance, such as lifting
heavier weights.
Just exercising doesn't strengthen bones either. Female marathon
runners sometimes stop menstruating and lose tremendous amounts
of bone, even though they may run more than 100 miles a week. To
regain bone, they have to eat more food which will usually start
them menstruating again, or they may need to take estrogen.
People with muscle and nerve diseases can also benefit from
lifting weights. They may be unable to work out as long or as
hard as a healthy person and they take longer to recover from
their workouts. However, if they stop exercising when their
muscles feel heavy or hurt and they take off when their muscles
feel sore, they can make dramatic increases in strength.
Anyone starting a weight training program should be guided by an
experienced instructor. Exercise with machines two or three
times a week, never on consecutive days. On each exercise, use
the heaviest weight you can lift comfortably eight or ten times
in a row. Then allow at least 48 hours for your muscles to
recover. Do not lift if they feel sore.
