A swimmer, on the other hand, is propelling himself through water -- a substance about twelve times as dense as air.

If that's not enough to get you moving in the pool, the American Heart Association reports that just 30 minutes of exercise per day, such as swimming, can reduce coronary heart disease in women by 30
