Sprint for Lean Legs

Sprints are cardio intervals, bringing the heart rate up fast and then letting it come down in between. This boosts metabolism and burns more calories than jogging at a steady rate and is a great way to get leaner legs, says Tom Holland, star of the Supreme 90 Day DVD System. Start incorporating sprints into your next cardio workout by moving as fast as you can for 15 seconds (with plenty of recovery in between) up to three times during your session.
