The right playlist doesn't mean just choosing a bunch of songs you hear on the radio. We're talking about creating a scientifically engineered mix that makes torching calories automatic. "Manipulating tempo can work like a remote control, telling your body to speed up or slow down without a heightened sense of exertion," says Carl Foster, Ph.D., professor of exercise and sports science at the University of Wisconsin in La Crosse.

Warm Up
Whether you're running, biking or elliptical-ing, you need to ease into cardio to prime muscles. So pick two songs at about 120 BPM.

Athletes were able to bike faster after warming up to music between 120 and 140 BPM, an Asian Journal of Sports Medicine study reports.

Sprint
Kick it up with three fat-burning intervals. You'll select a speedy song, follow it with a slow one, and repeat the combo three times.
