Sports drinks are actually engineered for sipping during workouts every 10 to 15 minutes to maintain your blood volume. In my mind, Gatorade, Powerade, and the like are made for working out, not for sipping. I try to avoid caloric drinks as it is, and don't enjoy the taste of sports drinks enough to seek them out when I'm not working out. What about you?
