Developed by Mari Winsor, this workout is a fast, fun, no-nonsense program requires only 20 minutes a day! Mari has designed the perfect program for when you don't have a lot of time to workout. You'll tighten and tone your buttock and thighs - all the while working your "Powerhouse" and corpuscles to get a flat, lean stomach. Plus, you'll improve your strength, coordination and posture.
