Yeah the real tricky thing they do is to make a 20oz bottle have 2.5 servings in it so the nutrition facts have lower numbers. Thats what got my attention, I saw 50 calories and looked further to see that was per servings.
I do my best to focus on the task at hand, and give 100% in what I'm doing at the time. Nothing else matters except the task at hand.
Sometimes I just squeeze fresh lime, or lemon juice into a bottle of filtered tap water. It adds a nice variation occasionally. But mainly after Intense cardio I get the gatorade/powerade powder and make it up 1/2 strength and then drink that.
but other than that, the only liquids that pass my lips are water, skim milk and maybe a diet coke 1-2 times a week
