HOW TO DO IT: Firmly grasp a seven- to 10-pound medicine ball - or a dumbbell that weighs between four and 10 pounds - overhead with both hands (keeping arms straight). Squat as low as you can go, toes pointing out. Remaining in the squat, walk slowly forward for eight steps, then slowly backward for another eight. Repeat the sequence.
