Stand in a Smith machine with feet about shoulder-width apart and positioned slightly forward of the bar. With your back upright and core braced, bend your knees and hips to lower into a squat until your thighs are roughly parallel to the floor. Press through your heels to rise back up in a controlled motion, focusing on leg muscle engagement throughout.
