Why is exercise important for your muscles and losing weight?

ANSWER

Strong muscles burn more calories. The more muscle mass you have, the more calories you burn even when you're not working out.

Studies estimate that for each pound of muscle you add to your body, you will burn an additional 35-50 calories per day. So an extra 5 pounds of muscle will burn about 175-250 calories a day -- or an extra pound of fat every 14-20 days.
