Sumo deadlift: proper form, muscles worked and common mistakes

Home › Exercises › Glutes › Sumo deadlift

How to do it

Wide stance with toes out and hands inside the knees. Drop the hips, lift the chest and drive the knees out over the toes; the torso stays more upright than in the conventional pull.

Muscles worked

Main muscle: glutes. Also worked: hamstrings. When it plans weekly volume, the generator counts each set of this exercise as one full set for glutes and half a set for each secondary muscle (what is known as fractional counting).

Sumo deadlift: pulling from the floor with the whole body, not just driving the hips

The hip thrust isolates hip extension with your back supported and the bar over your hips; the sumo deadlift lifts the bar from the floor with the whole body. The quads push the floor away at the start, the adductors and glutes work to open and extend the hips, and the back has to stay firm through the pull. With a wide stance and a more upright torso, the range is shorter than in the conventional deadlift, which usually means less torso lean and sometimes less lower-back load, though the hip mobility demand is higher.

It is a heavy, full-body lift for low reps, 3 to 6. It often fits better if you have good hip mobility for the wide stance, depending on your build, or if the conventional deadlift feels uncomfortable for your back. If your only goal is the glute, the hip thrust isolates it better; the sumo adds overall strength, and the two complement each other.

The detail that decides it: before pulling, take the slack out of the bar, meaning you tighten your body until the bar starts to bend against your hands, and push the floor away with your legs instead of pulling with your back. Keep the bar against your legs the whole way up.

Recommended sets and reps

As a compound lift, it fits in 3–5 sets of 5–12 reps leaving 1–3 reps in reserve (RIR). Prioritize it at the start of the session, when you're fresh.

Common mistakes to avoid

• Letting the bar drift away from your legs as you pull: the further it travels, the more leverage your lower back has to resist.
• Gripping the bar with each hand at a different distance from the center: one side works harder without you noticing.
• Leaving it for the end of the session: given the fatigue it creates, it goes better early on, which is where the generator places it.

What the research says

Because it is a multi-joint lift, the 2021 review of the repetition continuum by Schoenfeld and colleagues leaves room to choose: both heavy and moderate sets build muscle if they finish near failure, but maximal strength needs some heavy work.

You do not need to reach failure on every set: according to the meta-analysis by Refalo and colleagues (2023), stopping one or two reps short gives very similar growth. The generator prescribes it with RIR for that reason.

Frequently asked questions

What muscles does Sumo deadlift work?

Sumo deadlift mainly works the glutes muscle group, plus synergist and stabilizer muscles depending on the variation.

How many sets of Sumo deadlift should I do?

Between 3 and 5 sets per session, adjusting the total weekly volume for glutes to your level (about 10–20 sets per muscle per week).

Is a sumo deadlift easier than a conventional deadlift?

It depends on your build and mobility. The range of motion is shorter and the torso stays more upright, so many people find they can lift more or feel less lower-back strain. Others find the wide stance uncomfortable at the hips. Try both, and keep the one that lets you keep good form and progress.
