This abs workout, created by fitness expert Jessica Smith, star of the Yin Yang Fusion Workout DVD, combines the best of kickboxing and Pilates to challenge your abs in new ways -- without a single crunch.
For best results, perform each move back to back without rest, and depending on how much time (and energy) you have, repeat the full circuit up to three times total.
And remember, great abs start in the kitchen, so make sure to pair this routine with a healthy diet.
