I'm no doctor, but Red Bull on an empty stomach before the gym in the morning sounds like the worst drink possible. I knew a guy who drank Red Bull before and after the gym, immediately after he ate 2 snickers to "restore his energy tank", I think he lasted 2 months before he stopped his exercise efforts. Where do people get the idea that Red Bull and exercise is related? Have they started to market it that way perhaps?
