Five very different, very energetic 10-minute segments. The movement variety combined with Michelle Dozois' sincere enthusiasm is sure to keep you motivated. With never a wasted moment, it's totally focused on burning calories and carbs (since carbohydrates are the energy source your body uses first). The initial four sections each use a specific cardio style - basic aerobics, kickboxing, plyometrics and bootcamp/intervals. The fifth segment is a series of metabolism-boosting toning routines.
