Shoulder strength/mobility is tested during this leg exercise.
How To: Lift the bar directly overhead with a wide, overhand grip. Inhale and lower your body until your thighs are parallel to the floor. Imagine trying to sit in a chair that is directly below your butt. Exhale and extend your knees and hips, pressing through your heels to push your body up to starting position. Keep your back and neck straight and your head level.
