Six challenging ab workouts -- from 15 to 20 minutes each. Each program features different exercises and different workout styles. The moves range from straight-forward crunches, curls and Pilates exercises to stability and medicine ball routines. As always, Cathe's form is flawless and her cuing is superb. Note: the last part of the medicine ball workout is done with a partner. Requires a medicine ball and a stability ball. One workout uses ankle and wrist weights. ©2008.
