Stand under a Smith machine bar with feet about shoulder-width apart and the bar positioned slightly lower on your upper back. Hinge at the hips and bend your knees to lower into a squat while keeping your chest up and spine neutral. Once your thighs reach roughly parallel to the floor, drive through your heels to return to standing, emphasizing hip drive and glute engagement throughout the movement.
