Set the Smith Machine bar to upper-chest height and position it across the front of your shoulders with a clean-rack grip (elbows high, upper arms parallel to the floor).
Unrack and stand with feet shoulder-width apart and toes slightly turned out.
Descend by pushing your knees out and sitting your hips down, keeping your torso upright.
Lower until thighs are at least parallel to the floor, then drive through your heels to stand.
