Chocolate
The bioactive compounds tyramine and phenylethylamine found in chocolate can provide you with an energy boost for an intense exercise session. However, chocolate is packed with sugar, calories, fat, and caffeine, so don't go overboard. Your best bet is dark chocolate; it contains the fewest calories and the most antioxidants.

I always try to give myself a good hour after I eat before an intense workout.
