Stand as tall as you can with your feet spread slightly wider than shoulder width apart. Hold a dumbbell on each side and bring straight up over your shoulders. Your arms should be fully extended and palms facing out
Look straight ahead, and keep your torso as upright as possible for the entire exercise with your lower back slightly arched. Tighten your abs, bend your knees, and lower and push back your hips as far as you can into a squat position with your thighs almost parallel to the floor.
Push through your heels to return to the starting position and repeat to complete the set.
