Boost your energy and endurance with these natural power sources.

By Matthew Kadey

Whether you're training for a marathon or keeping up a sweet yoga practice, some goals rarely change: finding healthy ways to add energy, increase endurance, and enhance recovery. We looked at the latest research to identify foods that supercharge a workout and taste good, too.

Beets: New studies show that nitrates in the ruby-red root vegetable help your blood vessels dilate, increasing oxygen delivery to working muscles.

Apples: Recent data suggests that quercetin, a potent antioxidant found in apples, can improve exercise endurance.

Sweet Potato: Its high carbohydrate content makes the sweet potato a natural energy provider for long-lasting workouts. Plus, the sweet flesh is rich in immunity-boosting vitamin A.

Quinoa: The popular South American whole grain is chock-full of energizing complex carbohydrates and magnesium, an essential mineral recognized as being a key player in energy metabolism.

Yogurt: With its optimum balance of protein and carbs, yogurt is a stellar fuel for post-workout recovery. Choose plain Greek-style versions for more protein and no processed sugars.

Lentils: This humble legume is packed with iron, which researchers at Cornell University recently found to be essential to athletic performance.
