Who doesn't love a nice, cold glass of chocolate milk? Most of us may scoff and say, "that's for kids!" but the truth is that we secretly love chocolate milk. As a fitness bad-ass, it turns out that chocolate milk is something to add back into your life, no matter how old you are! A study conducted at Indiana University found that athletes who drank chocolate milk were better able to blast through their workouts. Participants drank chocolate milk after their first workout of the day, and when it came time to do their second workout, they were able to push harder and work longer without fatiguing.
