A question I get a lot is: do athletes need a sports drink or is just water okay? Here is the scoop... if you are exercising over one-hour consistently then yes, a sports drink would be best to fuel your body. Although, if you are exercising less than one-hour, just water will do!
Most importantly, drinking enough fluids is what is essential to maximize performance! Why? When you're just 2% under-hydrated your performance is compromised by 10 - 15%! Best advice: don't wait to drink until you are thirsty!
