How high should the deficit be for sumo deadlifts?

Most coaches use 1 to 2 inches for sumo, a little less than for conventional deficits, and a single plate under each foot is usually enough. A taller deficit makes it hard to reach the bar with a flat back in a wide stance, so raise the height only once the lower one feels controlled.

Can I stand on a platform instead of two plates?

Yes, as long as it is flat, stable and wide enough for your whole stance, with the barbell's plates still resting on the floor beside it. Two separate plates are popular for sumo because a wide stance rarely fits on a standard deficit block.

Should sumo lifters pull deficit sumo or conventional deficits?

Deficit sumo is the more specific choice if you compete sumo, because it trains the floor break where sumo pulls usually stall. The Barbell Deficit Deadlift trains the conventional pull and fits better as variety or for lifters who use both styles.

How much weight should I use for deficit sumo deadlifts?

Start clearly lighter than your floor sumo working weight, since even a 1-inch deficit makes the start much harder. Build the load over several weeks, and drop it if your hips start rising before the bar or your back rounds off the floor.

Is the deficit sumo deadlift a good choice if my hips feel tight?

Not yet. The deficit asks for more hip bend and turnout than a floor sumo pull, so build the floor version first and add a deficit once you can reach the bar with a flat back and your knees tracking over your toes.

Barbell Deficit Sumo Deadlift

What Is the Barbell Deficit Sumo Deadlift?

Barbell Deficit Sumo Deadlift is a compound exercise that primarily targets the glutes, quads and inner thighs and also engages the hamstrings, lower back, upper back and grip. It is an advanced-level movement in which you stand on a low platform, here a weight plate under each foot, and pull a barbell from below your usual starting height with a wide stance, toes turned out and hands inside your knees.

The sumo stance already shortens the pull. Filming lifters at a national powerlifting championship, researchers found that bar travel and mechanical work were roughly 25 to 40% greater for the conventional pullers than for the sumo pullers, who stood about twice as wide with a more upright trunk. Standing on a plate gives some of that range back: your hips start lower, your knees are more bent and you have to break the bar from the floor in a deeper position than a regular sumo pull asks for.

Powerlifters who compete sumo use it as an assistance lift, because a sumo pull most often stalls right as the bar leaves the floor. It is usually done from a small deficit of 1 to 2 inches, with less weight than floor sumo, after or in place of the main deadlift on a pulling day. Compared with the conventional style, a study of 30 experienced male lifters pulling at 85% of their max found the sumo deadlift produced more vastus lateralis activity early in the lift, while the conventional deadlift produced larger hip extension moments and more biceps femoris activity. The deficit stretches out that quad and adductor-heavy start, and the glutes take over to finish the lockout. Lifters who pull conventional get the same longer range from the Barbell Deficit Deadlift or the Trap Bar Deficit Deadlift.

It suits lifters who already sumo deadlift with a consistent setup and have the hip mobility to reach the bar with a flat back from a deeper position. If the Barbell Sumo Deadlift from the floor is still new, groove the stance with the Kettlebell Sumo Deadlift or the Dumbbell Sumo Deadlift first, then add a deficit only once the floor pull looks the same from rep to rep.

Instructions

Set two flat weight plates on the floor just behind a loaded barbell, spaced for your sumo stance, and stand with one foot fully on each plate.
Take a wide stance with your toes turned out and the bar over the middle of your feet, close to your shins.
Push your hips back and bend your knees, pushing them out over your toes, until you can reach the bar.
Grip the bar with both palms facing you, hands about shoulder-width apart and inside your knees, with your arms straight.
Lower your hips until your shins touch the bar, flatten your back and lift your chest so your torso is fairly upright.
Take a deep breath, brace your core and pull the slack out of the bar until you feel tension through your arms and legs.
Push your feet down and out into the plates and lift the bar, keeping your knees out and your hips and chest rising together.
Keep the bar close to your legs as it passes your knees, then drive your hips forward to stand up.
Finish standing tall with your hips and knees fully extended and your shoulders over the bar, without leaning back.
Lower the bar under control by pushing your hips back and bending your knees, keeping your knees out, until the plates touch the floor, then reset and brace before the next rep.

Common Mistakes

Using too tall a deficit
Standing on a platform higher than you can reach with a flat back turns the start into a rounded-back pull instead of a deeper sumo position.
Hips shooting up first
Letting the hips rise before the bar moves throws away the deeper start the deficit is there to train and leaves the lower back doing the lift.
Knees caving in
Letting the knees drift inside the feet as the bar breaks the floor loses the leverage of the wide stance and strains the knees and groin.
Unstable footing
Feet hanging off the edge of the plates, or plates of different heights, let a foot rock or slip while the bar is heavy.
Yanking the bar off the floor
Jerking the bar without first pulling the slack out loosens the back and hips at the bottom, where the deficit makes the position hardest to hold.
Using floor sumo weights
Loading the bar like a regular sumo pull makes a clean start from the deficit impossible and turns each rep into a grind with poor positions.

Injuries

Barbell Deficit Sumo Deadlift is a medium risk exercise when performed with proper technique. The deeper start puts the groin and inner thighs under heavy load in a stretched position, and the lower back has to stay flat from a lower hip height than in a floor pull. The hips and knees take more twisting and sideways stress than in a conventional deadlift, especially if the knees drift inward as the bar leaves the floor.

Keep the deficit small, about 1 to 2 inches, and use clearly less weight than your floor sumo. Warm up the hips and groin before heavy sets, take a stance width you can reach with a flat back, and keep your knees pushed out in line with your toes for the whole rep. Stand on flat, stable plates of the same height with your whole foot on each one. A double overhand grip, a hook grip or straps spare the biceps of the arm that would turn palm up in a mixed grip.

To regress, lower the deficit, return to the Barbell Sumo Deadlift from the floor or use the Kettlebell Sumo Deadlift to rebuild the position. Strengthening the inner thighs with the Copenhagen Plank helps the groin handle the stance. To progress, add load to a deficit you can already control before making the deficit taller.

Stop if you feel a sharp pull or pain in the groin, a pinching pain at the front of the hip, sharp pain in the lower back, pain or tingling running into a leg, or a pop at the front of the elbow. Lifters with existing hip pain should check with a clinician before training a deep, wide-stance pull.
