Do you drink sports drinks while you workout? I do. Some people say that it hurts a workout because of the calories; however, if you're not working out to lose weight, it helps. If you workout in the morning before breakfast, a sports drink helps give you energy and carbohydrates which help fuel the muscles. When I workout, I workout for a long period of time...usually about 2.5 to 3 hrs. After an amount of time, your muscles become depleted of carbohydrates and other "stuff" that is necessary for a successful workout. Sports drinks help replinish these needs. So I would say, unless your main goal is to lose weight, which it may very well be, sports drinks while working out are a good idea.
