How wide should my stance be?

Start with your feet about one and a half to two times shoulder width and your toes turned out 30 to 45 degrees. Then adjust until your knees can follow your toes and you reach parallel without your heels lifting or your lower back rounding.

Is the sumo squat better for the glutes than a regular barbell squat?

Not necessarily. In competitive bodybuilders squatting 80% of their max to parallel, doubling the stance width raised inner-thigh activity on the way up but did not change gluteus maximus activity compared with a regular-stance back squat. Both versions train the glutes hard, so choose the stance that suits your hips and goals.

How is it different from a sumo deadlift?

Both use a wide, toes-out stance, but the sumo squat starts standing with the bar on your back and lowers into a squat with an upright torso. The Barbell Sumo Deadlift lifts the bar from the floor with your hands inside your knees and relies more on a hip hinge.

How deep should I squat?

Aim for your thighs to reach at least parallel to the floor. Sink deeper only if your hips allow it without your lower back rounding or your heels lifting.

Do I need a squat rack?

Yes, for any meaningful load. A rack lets you unrack the bar at upper chest height instead of lifting it overhead onto your back, and its safety pins or arms catch the bar if you miss a rep.

Barbell Sumo Squat

What Is the Barbell Sumo Squat?

Barbell Sumo Squat is a compound exercise that primarily targets the upper legs and glutes, with extra emphasis on the inner thighs, and also engages the lower back and core. It is an intermediate-level movement that combines a barbell back squat with a stance well wider than shoulder width and the toes turned out.

The wide stance lets the hips sit down between the legs, so the torso stays more upright than in many regular squats while the hips and inner thighs take on a bigger share of the work. It is usually programmed as a main or accessory lift on a lower-body day, either in place of a regular Barbell Squat or after it for extra hip and adductor volume, and it suits the same strength and muscle-building rep ranges.

Turning the feet out and pushing the knees wide brings the hip extensors and rotators into play alongside the quads. A motion-capture study of men and women squatting with a barbell found that a wide stance demanded more hip extensor and hip outward-rotation effort than medium or narrow stances. The adductors, especially the large adductor magnus, help extend the hips out of the bottom, which is why the movement is known for training the inner thighs. The quads still work hard throughout, so it remains a full lower-body lift rather than a hip-only exercise.

The Barbell Sumo Squat suits lifters who want more hip and inner-thigh work from their squatting, and those who find a wider stance more comfortable for their hips. It needs enough hip mobility to turn the knees out over the toes at depth, so build up with a wide-stance Kettlebell Goblet Squat or Dumbbell Sumo Squat and a solid regular Barbell Squat first. The Smith Machine Sumo Squat is a useful stepping stone when balancing a free bar in a wide stance is the limiting factor.

Instructions

Set the bar in a squat rack at upper chest height and set the safety pins or arms just below the depth you plan to reach.
Step under the bar and rest it across your upper back, on the muscles just below your neck, gripping it with your hands well outside shoulder width.
Brace your core, stand up to lift the bar off the hooks and take two or three short steps back.
Set your feet well wider than shoulder width, about one and a half to two times, with your toes turned out 30 to 45 degrees.
Take a breath, brace, and lower by bending your hips and knees together, pushing your knees out so they stay in line with your toes.
Keep your chest up and your torso close to upright, and lower until your thighs are about parallel to the floor.
Drive through your whole foot to stand back up, keeping your knees pushed out and squeezing your glutes at the top.
After the final rep, walk the bar forward into the rack and set it on the hooks before stepping away.

Common Mistakes

Knees caving inward
Letting the knees drift inside the line of the toes stresses the inner knee and takes work away from the glutes and adductors.
Stance too wide
Setting the feet wider than your hips can handle limits depth, lifts the heels or pinches the front of the hip, and raises the risk of a groin strain.
Toes pointing straight ahead
Keeping the feet straight in a very wide stance makes it hard to push the knees out over the toes, so depth suffers or the knees cave.
Leaning too far forward
Letting the chest drop and the hips shoot back shifts the load onto the lower back and gives up the upright torso the wide stance is meant to allow.
Bouncing at the bottom
Dropping fast and rebounding out of the bottom loads the inner thighs and hips at their most stretched point.
Bar resting on the neck
Placing the bar too high on the spine causes neck discomfort and makes it harder to keep the upper back tight under load.

Injuries

Barbell Sumo Squat is a medium risk exercise when performed with proper technique. The wide stance adds demands on the groin, hips and knees on top of the usual squat strain points, and the most common trouble spots are the inner thigh at the bottom of the squat, the inner knee when the knees cave, the front of the hip when the stance is wider than your mobility allows, and the lower back when the torso tips forward.

Warm up with bodyweight wide-stance squats or a few sets of Cossack Squat before loading the bar, and pick a stance width that lets your knees follow your toes all the way down. Lower under control rather than dropping and bouncing, since the adductors are at their longest at the bottom. Squat inside a power rack with the safety pins or arms set just below your lowest point, and start lighter than your regular squat, because the wider stance is a new position even for experienced lifters.

To regress, hold a kettlebell or dumbbell for a wide-stance Kettlebell Goblet Squat or Dumbbell Sumo Squat, or use the Smith Machine Sumo Squat to take balance out of the lift. A wide-stance Barbell Box Squat helps control depth while you build mobility. To progress, add load gradually or pause briefly at the bottom of each rep.

Stop the set if you feel sharp pain in the groin or inner thigh, a pinching pain deep in the front of the hip, pain around the kneecap, or back pain that spreads into the buttock or leg.
