A. Stand with your feet slightly wider than a hip's distance apart. Grasp a medicine ball with both hands, holding the ball just above your right shoulder as if it were an axe that you were getting ready to swing.
B. Bend your left knee and lower yourself into a half squat, keeping the right leg extended. As you bend your knee, swing your axe (the ball) in a diagonal wood-chopping motion, bringing the ball toward and just past your left knee. Rise to the starting position. Repeat to complete 12 to 15 sets, then switch sides.
