Smith Sumo Squat

How to do the Smith Sumo Squat

1. 1Set the Smith machine bar at roughly upper-chest height and load it with your working weight.
2. 2Step under the bar and position it across your upper trapezius, just below the base of your neck. Grip the bar wider than shoulder-width for balance and retract your shoulder blades.
3. 3Place your feet wider than shoulder-width — typically 1.5 to 2 times shoulder-width apart — with toes angled outward 30–45 degrees.
4. 4Unrack the bar by rotating it to disengage the safety hooks, then stand tall with your core braced and chest up.
5. 5Inhale, brace your core, and begin the descent by driving your knees outward in line with your toes while hinging slightly at the hips.
6. 6Lower until your thighs are at least parallel to the floor, keeping your torso as upright as possible and your heels firmly planted.
7. 7Drive through your entire foot to press the floor away, extending your hips and knees simultaneously to return to the standing position.
8. 8Exhale at the top of the movement and reset your brace before the next rep.
9. 9At the end of your set, rotate the bar back onto the safety hooks and confirm it is fully secured before stepping out from under the bar.

Form tips

• Actively push your knees outward throughout the entire range of motion to keep them tracking over your toes — this maintains tension on the adductor magnus and gluteus medius and protects the knee joint.
• Set the Smith machine's safety catches just below your lowest squat depth before starting — this allows you to safely abort a set without a spotter if you reach failure.
• Keep your chest tall and your gaze level; excessive forward lean shifts the load away from the gluteus maximus and onto the lower back.
• Pause briefly at the bottom for one count before driving up — this eliminates the bounce reflex and ensures muscular effort rather than elastic rebound drives the ascent.
• Experiment with foot width and toe angle within the sumo range across warm-up sets to find the position that allows the deepest squat without heel rise or knee cave.

Common mistakes

• Allowing the knees to cave inward (valgus collapse) during the ascent — this reduces gluteus medius activation and places harmful shear stress on the knee ligaments.
• Rising onto the toes at the bottom of the squat — heel rise shifts the center of mass forward, limits depth, and transfers load from the gluteus maximus and quadriceps to the lower back.
• Using too narrow a stance — a stance near shoulder-width eliminates the wide-stance adductor magnus and gluteus medius recruitment that defines the sumo squat, turning it into a conventional squat.
• Descending too quickly and bouncing out of the bottom position — momentum at the lowest point reduces time under tension for the gluteus maximus and quadriceps and can strain the knee.
• Skipping the safety catch setup or setting the catches too low — without catches at the correct height, a missed rep on the Smith machine has no safe bail option.
