30-Minute Workout: Cardio and Abs

Combo Workout: Quick Cardio and Kickass Abs

Today's workout in our Better-Body Challenge is a fun calorie-burning, ab-toning session. And it only takes 30 minutes. Start with 20 minutes on the treadmill, playing with both speed and incline (or try this elliptical workout). Then end your sweat session with 10 minutes of hardcore ab work! You've been working hard all month, so this quick workout is more about maintenance. Keep it up!
