The Triple-Play Cardio Plan

Want to fire up your fat-burning furnace? Make your workout a three-way, logging equal amounts of time on the stair-climber, elliptical, and treadmill. "Performing short stints on several machines allows you to work at a higher intensity for a longer period, which increases the number of calories you torch," says Jessica Matthews, an exercise physiologist for the American Council on Exercise, who designed this routine. Plus, breaking up your session into 10-minute segments makes the time fly by. So come on and mix it up at the gym-your body (and mind) will thank you.
