You'll “Train Like a Contender” with two different workouts: boxing-style cardio and athletic aero/tone intervals. Both programs maximize results by combining fast-paced movements with non-stop action. The boxing segment uses easy-to-follow, eight-count combos. But it's challenging — your upper and lower body are constantly in motion (jabs, hooks and crosses blended with shuffles, skips and marches). The aero/tone workout is equally tough. Its cardio intervals include plyometric jumps and leaping lunges. While its toning drills range from cross-chops to reverse lunges (this workout ends with abs and arms floorwork). Weighted gloves are optional. ©2011.
