Smith Machine Squat
The smith machine squat is a guided barbell squat variation targeting the quads, glutes, and hamstrings. The fixed bar path provides additional stability compared to a free barbell, making it suitable for beginners learning squat mechanics or for isolated muscle focus.
How to do it
- Set the bar height on the smith machine to shoulder level and step under the bar.
- Position the bar across your upper back and release the safety latches.
- Stand with feet shoulder-width apart and toes pointed slightly outward.
- Lower into a squat until your thighs are parallel to the floor.
- Press through your heels to return to standing.
- Re-engage the safety when complete.
Form cues
- Keep your chest lifted throughout the movement.
- Drive through your heels as you stand back up.
- Keep your knees tracking in line with your toes.
- Maintain a flat back against the fixed path.
Breathing: Inhale as you lower down into the squat, and exhale as you press back up to the starting position.
Common mistakes
- Placing feet too far forward can over-stress the knees and limit your depth.
- Lifting heels off the floor reduces stability and shifts balance forward.
- Rounding the lower back can place unnecessary stress on the spine.
Muscles worked
Primary: quads. Secondary: glutes, hamstrings, lower back.
