The Sumo Squat: A Complete Guide From First Rep to Advanced Variations

Quick Intro

The sumo squat is a lower-body exercise performed by squatting with the feet set wide and the toes turned outward, lowering the hips straight down between the legs and standing back up.

Equipment Needed

None. A sumo squat needs nothing but floor space.

Why the Sumo Squat Matters

The sumo squat asks the front of the thigh (quadriceps, specifically the rectus femoris and vastus medialis) to control the descent and drive the ascent, while the glutes (gluteus maximus) extend the hip back to standing. The wide, toes-out stance also brings the inner thigh (adductors) and side glute (gluteus medius) into the movement far more than a standard squat does, since the wide base changes the angle those muscles work through.

That inner-thigh and glute emphasis is what actually separates this exercise from a standard squat, not just the wider stance for its own sake. A regular squat keeps the feet roughly shoulder-width and the load moving mostly straight up and down through the quads and glutes. Turning the feet out and widening the stance shifts a share of that load sideways onto the adductors, a muscle group a standard squat works far less.

The sumo squat is a useful muscular endurance exercise for the quads, glutes and adductors, with muscular strength carryover as well. The wide, externally rotated hip position asks for flexibility too.

When to Do It

The sumo squat fits well anywhere in a lower body session, and works equally well as a stand-alone strength movement or worked into a faster-paced circuit. Paired with a regular squat it trains both stance widths in one workout, and a set or two makes a useful warm-up before loaded sumo squats or sumo deadlifts. Two to three sessions a week on non-consecutive days lets the legs recover fully between sessions.

• Existing hip or groin tightness. The wide, externally rotated stance asks more of the hip’s range of motion than a standard squat does. Starting with a narrower stance and a shallower depth, widening gradually as the hips open up, is the safer approach until that range feels comfortable.
• Knee discomfort in the wide stance. This usually comes from the knees drifting inward off the line of the toes, which loads the joint unevenly. Narrowing the stance slightly and turning the toes out a little less while the tracking improves is a reasonable adjustment.

For most people without an active hip issue, this is an effective way to train the inner thighs and glutes without any equipment.

Getting Ready

A minute of hip circles and a few bodyweight squats at a standard stance warm up the hips before asking them to move through the wider, more externally rotated range this version demands.

Turn the toes out roughly 30 to 45 degrees and track the knees directly over the toes as the hips sink straight down, rather than letting the knees cave inward toward each other.

Step-by-Step Instructions

1. Starting position. Stand with your feet wider than shoulder width, toes turned outward roughly 30 to 45 degrees.

2. The descent. Sink your hips straight down between your legs, keeping your knees tracking out over your toes and your chest lifted.

3. The ascent. Push back up to standing by driving through the whole foot, squeezing the glutes and inner thighs at the top.

Repeat for the full set, keeping the same stance width and depth on every rep.

How Many, How Often

Letting the knees cave inward toward each other is the easiest way to make the wide stance feel more comfortable while quietly taking work away from the adductors and side glute that are supposed to be doing it, so knee tracking matters more here than depth alone.

Modifications and Variations

The sumo squat has one close relative, which changes the muscle emphasis without being easier or harder.

For a different technique, the Bodyweight Squat uses a standard shoulder-width stance, shifting the emphasis back toward the quads and glutes and away from the adductors this wider version adds.

Widening the stance further, or adding a brief pause at the bottom of the range, are reasonable ways to add difficulty within this exercise. With no added weight, load runs out before technique does, so once 20 or more clean reps at full depth are manageable, holding a light weight at the chest, such as a book or a filled water bottle, keeps adding demand without changing the stance. In the other direction, a narrower stance with less toe turnout reduces the demand while the hips and knees adjust to the pattern.

Common Mistakes to Avoid

Letting the knees cave inward. This is the fault that defeats the exercise’s purpose, since caving knees take the inner thigh out of its stretched, engaged position. Tracking the knees out over the toes keeps the rep honest.

Using too narrow a stance for a true sumo squat. A stance that’s only slightly wider than standard doesn’t create enough of an angle change to meaningfully shift the load onto the adductors. Widening the stance until the outward-turned toes and the deeper hip angle are both clearly present keeps the intended emphasis real.

Leaning the torso too far forward. Collapsing forward at the hips shifts load toward the lower back and away from the glutes and quads. Keeping the chest lifted and the torso closer to upright keeps the target muscles doing their share of the work.

Shifting weight onto the toes. Letting the heels lift or the weight drift forward reduces glute engagement and increases strain on the knees. Keeping weight distributed through the whole foot, heels included, keeps the glutes properly engaged.

Turning the toes out too far or not far enough. Both extremes make the squat feel awkward and limit how deep the hips can comfortably go. The 30 to 45 degree range is a starting point, and the right angle is the one that lets the knees follow the toes through a full, comfortable range.

Cutting the depth short late in the set. Stopping the descent early as fatigue builds shortens the range and reduces how much the inner thighs and glutes work. Keeping the depth the same from the first rep to the last keeps the set meaningful.

After Your Set

The wide, externally rotated stance leaves the inner thighs and hips with real tension by the end of a set. A seated butterfly stretch, soles of the feet together and knees easing toward the floor, lengthens the adductors through the same rotated position they just worked in. A standing quad stretch afterward, pulling one heel gently toward the glutes, releases the front of the thigh that drove every rep.

Going Deeper

The sumo squat sits alongside the standard squat as an emphasis variation, usually added by anyone who already handles a full squat progression and wants to bring more inner-thigh and glute work into a session. It pairs naturally with a hinge-pattern exercise like the Hip Hinge in the same session, balancing a wide-stance squat with a hip-dominant movement.

The stance quietly narrowing back toward a standard squat width as fatigue sets in is what usually stalls progress here, letting someone finish a set while the adductors and side glute do progressively less of the intended work. The fix is checking the foot position at the start of every set and resetting it if it’s drifted narrower, rather than letting the stance shrink rep by rep.

Someone with a strong standard squat already can expect ten clean reps at a comfortable wide stance within the first one to two weeks, and twenty reps at full depth somewhere in the four to six week range.

How to Know You’re Improving

1. Ten clean reps at a shallow depth with the knees tracking correctly
2. Fifteen reps completed at a deeper, near-parallel depth
3. Twenty reps in a row with a consistent wide stance held throughout
4. A controlled 3 second lower maintained on every rep of a full set

A rep counts as clean when the knees never cave inward, the weight stays distributed through the whole foot and the stance width stays consistent from the first rep to the last. Consistent knee tracking through the full set matters more here than how many reps get completed.

Muscles Worked

• Rectus Femoris (one of the quadriceps at the front of the thigh, extending the knee out of the wide stance)
• Vastus Medialis (the inner portion of the quadriceps, working harder with the feet turned out)
• Gluteus Maximus (the largest glute muscle, extending the hips to stand from the wide bottom position)
• Adductors (the inner thigh muscles, taking far more work than they would in a narrow squat)
• Gluteus Medius (a smaller glute muscle at the side of the hip, holding the knees tracking out over the toes)

FAQ

How is a sumo squat different from a regular squat? The wider, toes-out stance shifts load onto the inner thighs and side glute, muscles a standard shoulder-width squat works far less.

How wide should my stance be? Wide enough that the toes turn out 30 to 45 degrees and the hips can sink straight down between the legs. A stance that’s too narrow won’t create the intended shift in emphasis.

Is the sumo squat harder than a regular squat? Not necessarily harder overall, just different in emphasis. It trains the adductors and side glute more directly, while a standard squat leans more on the quads and glutes.

Can I do sumo squats if I have tight hips? Yes. Starting with a narrower stance and shallower depth and widening gradually works better than forcing full width and depth from the first session.

Why do my knees hurt more in this squat than a regular one? That usually points to the knees drifting inward off the line of the toes. Narrowing the stance slightly helps while that tracking improves, and pain that stays is worth showing to a doctor or physical therapist.

Should I do sumo squats in place of regular squats, or both? Both, ideally. Each stance works a somewhat different part of the hip’s range, and neither fully replaces the other.
