Answer:
Swimming is an excellent way to work your entire body and cardiovascular system. An hour of swimming burns almost as many calories as running, without all the impact on your bones and joints. Swimming is the fourth most popular activity in the United States.
Swimming is an efficient way to burn calories. A 160-pound person burns approximately 423 calories an hour while swimming laps at a low or moderate pace. That same person may burn up to 715 calories an hour swimming at a more vigorous pace.
It burns any excess fat that your body has reserved for energy, regardless of whether this fat is located on your stomach, hips, thighs, or other parts of your body.
