Heavy Ball Floor Workout

The heavy ball supplies the resistance as Gilad takes you through all the core muscle groups. Lots of core workouts neglect the mid and upper back muscles--but not this one! Core Challenge is beautifully designed to work both the entire abdominal region and the opposing back muscles, to help you develop a stronger, balanced midsection. NOTE: A 3- to 5-lb. dumbbell can be used instead of a heavy ball
