Blueberries Superpower: fuel fitness Fat-blasting cardio is an essential ingredient for sexy, sculpted abs—and antioxidants in berries enable you to step up crucial conditioning.

How they work "Antioxidants help improve blood flow—which delivers more oxygen to your muscles," says Leslie Bonci, R.D., director of sports nutrition at the University of Pittsburgh Medical Center. "Giving your muscles the oxygen they need makes exercise feel easier, so you may work out harder, longer and more often." Blueberries and blackberries top the antioxidant chart; try them on whole-grain waffles or in a turkey-lettuce roll-up.
