Dumbbell Sumo Squat

You take a wide stance with the toes turned out, hold a single dumbbell at the chest or hanging between the legs, and squat straight down between the heels. The wide base brings the inner thighs into the work alongside the quads and glutes, and most beginners find staying upright easier here than in a narrow squat. Coached by Maddy (NASM-CPT) — these are the exact form cues he gives on every client's first week.

Level — Beginner

Beginner — one of the most forgiving loaded squats; ideal for learning depth with an upright chest.

Proper form — 5 cues

  1. Set the feet about one and a half shoulder-widths apart, toes turned out 30-45 degrees.
  2. Hold the dumbbell vertically at the chest or hanging at arm's length — either way, shoulders stay pulled back.
  3. Track the knees out over the middle toes for the entire descent.
  4. Squat straight down between the heels with the torso tall.
  5. Push the floor apart with both feet as you stand.

Breathing: Inhale and brace at the top, descend on the hold, exhale driving up out of the bottom.

The 3 mistakes Maddy corrects most

Knees caving inward on the way up. The wide stance amplifies any collapse, loading the knee joints instead of the inner thighs and glutes. Fix: Screw the feet into the floor and drive the knees out over the toes from the first centimetre of the ascent.
Wide feet with the toes still pointing forward. A turned-in stance at this width pinches the hips and blocks depth before the muscles are even challenged. Fix: Match the toe angle to the stance — the wider the feet, the more the toes turn out.
Hips shooting up first out of the bottom. When the pelvis rises before the chest, the lift becomes a stiff-legged heave and the lower back takes over. Fix: Lead the ascent with the head and chest, hips and shoulders rising at the same rate.

Common questions

What does the sumo squat work that a regular squat does not?

The turned-out wide stance lengthens the adductors — the inner-thigh muscles — so they contribute far more to each rep, alongside the glutes and quads. The upright torso also reduces lower-back demand. It does not replace the standard squat; it widens the recruitment map, which is why programmes often carry both.

How heavy can I go holding just one dumbbell?

Grip and the awkwardness of holding a single weight cap the load before the legs do, usually somewhere around the heaviest dumbbell you can hold for the set. Beyond that, progress through slower descents, pause reps at the bottom, or one-and-a-half reps — all raise difficulty without needing a heavier bell.

Should my heels lift at the bottom?

No — both heels stay welded down; the wide stance normally makes that easier, not harder. If they still lift, the stance may be too wide for your hip anatomy or the ankles too stiff. Narrow the feet slightly, reduce depth to where the heels hold, and work ankle mobility separately.
