Sumo Squat
The sumo squat is a wide-stance, toes-out squat holding one dumbbell, either hanging between your legs or held at your chest. It works the glutes, inner thighs (adductors) and quadriceps with no bar on the back, and it is a straightforward way to load a wide-stance squat.
Also called: Sumo Goblet Squat, Wide Stance Squat, Dumbbell Plié Squat, Wide-Stance Dumbbell Squat · Equipment: dumbbell · Pattern: squat
Step by step
- Stand with your feet wider than shoulder width and your toes turned out about 30–45°.
- Hold one dumbbell upright by one end with both hands, arms long so it hangs between your legs, or hold it close to your chest.
- Brace your trunk and stand tall with your shoulders down.
- Bend your knees and hips together and sink straight down, pushing the knees out so they track over the toes.
- Descend until your thighs are about parallel to the floor or as deep as your heels stay down. The hanging dumbbell stays just off the floor.
- Drive through the whole foot to stand back up, squeezing the glutes at the top.
- Keep the chest up and the dumbbell close to your body for every rep.
- Knees out over the toes
- Sit straight down between your heels
- Chest up, dumbbell close
- Whole foot on the floor
- Squeeze the glutes to stand tall

What goes wrong, and the fix
Knees caving inward
Fix: Push the knees out so they track over the turned-out toes on every rep.
Toes pointing forward
Fix: Turn the toes out about 30–45° so they match the direction of the knees.
Heels lifting
Fix: Keep the whole foot flat and sink only as deep as your heels stay down.
Chest dropping forward
Fix: Keep your chest up and let the dumbbell hang straight down between your legs.
Dumbbell hitting the floor
Fix: Stand on two low plates or steps, or hold the dumbbell at your chest, to reach full depth.
Cutting depth short
Fix: Sink until your thighs are about parallel to the floor on every rep.
What the research says
General fitness · first choiceEndurance · first choiceFat loss & conditioning · first choiceStrengthMuscle growthRehab & prehab
- Stance width — Lab studies found a wide squat stance raised glute and inner-thigh muscle activity compared with narrower stances, while front-thigh activity was unchanged. That is a measure of activity, not of growth.
- Inner-thigh focus — In a lab comparison of six exercises, the sumo squat produced the least inner-thigh (adductor longus) activity, and side-lying hip adduction produced the most.
- Depth — In a 10-week study, full-depth squats grew the glutes and inner thighs more than half squats, while front-thigh growth was similar.
- Load and effort — Research comparing loads finds muscle growth is similar across a wide range of loads when sets are taken close to failure. Studies show sets that finish a few reps short of failure capture most of the growth benefit.
- Volume and frequency — Research links more weekly sets for a muscle to more growth, with diminishing returns. Around 10 or more hard sets a week has been associated with more growth than fewer than 5, and training a muscle about twice a week is a common way to spread that volume.
