Designed to blast your midsection and give you chiseled abs

Each workout is completely different so you stave off boredom and prevent plateaus. Mix and match based on your schedule and how much time YOU have to exercise. If you only have 10 minutes, choose one workout. If you have 20 minutes, do two -- and so on. You can even mix and match them with the workouts from 10 Minute Body Transformation DVD! As always, Jillian offers modifications and progressions for every move in each workout.
