A side-step squat with wood chop works your arms, torso, abs, back, legs, inner thighs and butt. Stand with your feet shoulder-width apart holding a three- to four-pound medicine ball or dumbbell as resistance equipment in your hands. Bend your arms up so that the resistance is at eye level over your right shoulder. As you bring the piece of equipment toward your left knee, step out with your left leg and bend it no further than 90 degrees, keeping your right leg straight. Return to the starting position. Do 10 to 15 reps and repeat on the other leg.
