What 12 Top Trainers Do After Their Workouts

"I eat right away, and I always eat the same thing because I'm a ritualistic dude," says Gunnar Peterson, CSCS, a Beverly Hills personal trainer. "I take 30 ounces of water, some protein powder, some blueberries and some powdered amino acids, mix it in a huge bowl and put it in the freezer before my workout. By the time I'm done, it's like a slushie with a little bit of crunch. My wife thinks it's disgusting." Research supports Peterson's fruit choice (if not the rest of his combo). A study in the Journal of the International Society of Sports Nutrition suggests that fueling up with blueberries before and after a workout may help muscles regain strength faster and lower your levels of exercise-induced oxidative stress.
