Include Intervals

Cyclists who pedaled at an all-out effort with high resistance for a total of five 30-second sprints (that's just 2.5 minutes!) burned a whopping 200 calories, according to recent Colorado State University research.

"Changing the intensity forces your muscles to work harder," says Andia Winslow, a personal trainer in New York City.
