Based on Brad Schoenfeld’s High-Energy Fitness training program and featured in his best-selling book Look Great Naked, the three workouts on this program are designed to optimally work the muscle groups in your buttocks and hamstring muscle groups. Emphasizing the quality rather than the quantity of your training, Brad instructs you in the proper and effective way to exercise and sculpt, tone and develop your butt. The workouts are short yet very effective – taking no more than 12 minutes each to complete.
