Set the bar on a Smith machine at about shoulder height and stand in a split stance with your front foot elevated on a bench or step. Place the bar across your upper back and keep your chest up and core engaged. Lower your body by bending your front knee until your thigh is roughly parallel to the floor while the rear foot stays elevated. Press through the front heel to return to standing. Complete all reps on one leg before switching to the other.
