Best Cardio Ever: 15 Ways to Make It Really Work

Eat Smarter

Fuel Up First

Even if you're a get-up-at-the-crack-of-dawn-for-a-workout person, you need something in your stomach before heading out, says Seebohar. "You'll go stronger if you have a 100- to 200-calorie snack with some carbs and a little protein, like a banana or half a whole wheat bagel with peanut butter," he says.

Replenish ASAP

"There's a 30- to 60-minute window after exercise when your body restores glycogen, or energy. If you refuel during this period, you'll improve muscle recovery and help to better prepare yourself for the next workout," says Seebohar. Some good options: A non-sugary sports drink with sodium to replace lost electrolytes and a complex carbs/lean protein combo, such as a turkey sandwich.
