Weight Control Because exercise helps use oxygen, it causes your body to burn stored fat and helps you maintain a normal weight. For instance, if you walk four miles a day, four times a week, you can burn about 1,600 calories, or nearly half a pound a week. If you don't change your diet at all and keep walking the same distance over six months, you'll lose 12 pounds. Walk the same distance for a year and you'll drop 24 pounds! webmd.com
Stronger Muscles Muscle mass is a metabolically active tissue. In other words, 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 five pounds of muscle will burn about 175-250 calories a day, or an extra pound of fat every 14-20 days. Because men have more muscle mass, they burn calories faster and lose weight more easily than girls. So girls need to work out daily to stay strong and in shape. webmd.com
Better Skin Exercise also boosts circulation and the delivery of nutrients to your skin, helping to detoxify the body by removing toxins or poisons. As exercise boosts oxygen to the skin, it also helps increase the natural production of collagen, the connective tissue that plumps your skin. Your skin color is also improved after exercise because of the increase in blood flow.
