Some guys swear by the conventional deadlift. Others won’t touch anything but sumo. And the truth is, both camps are right — because neither variant is universally better, harder or easier than the other.
Although both exercises are very similar, they have their own unique requirements and accentuate different parts of the body, so your choice should depend on your body composition and personal bodybuilding goals.
It’s important to note that there are no factors that make either variant easier or harder — it all depends on your individual strengths and weaknesses.
So, what exactly are their differences? And more importantly, which one should you be using?
The Core Difference
The fundamental difference between sumo and conventional is stance width — and that one change creates significantly different mechanics, muscle emphases and demands on your body.
With the conventional deadlift, your feet are roughly shoulder-width apart and your hands grip the bar outside your legs. With sumo, your feet are significantly wider, toes flared out, and your hands grip the bar inside your legs.
Hip extension demands are almost identical between the two variants — that’s one of the most consistent findings in deadlifting research. The differences show up everywhere else.
The Conventional Deadlift
The conventional deadlift transfers a big part of the workload from the quads to the lower back, which essentially means it’s more efficient for strengthening the lower back than the sumo variant.
However, conventional deadlifts are tougher on your spinal erectors. Multiple deadlifting studies show that spinal extension demands are approximately 10% higher in the conventional deadlift. In other words, keeping the back extended as the bar breaks off the floor results in a harder contraction of the spinal erectors — and this can increase the risk of injury in guys with a weak lower back.
On the other hand, for higher or max reps, conventional is generally the better option. And it also works best for guys with a shorter torso.
Conventional is your best bet if:
- Your lower back is healthy and strong
- You have a shorter torso
- You want to prioritize lower back and overall posterior chain development
- You’re doing higher rep work

The Sumo Deadlift
The sumo deadlift has its own set of attributes, starting with a shorter range of motion. Within powerlifting competitions, this variant is a fully accepted alternative to conventional — and some of the strongest deadlifters in the world pull sumo, which should end any debate about whether it “counts”.
Although the motion is the same, the wider stance required makes a big difference in the results. This variant is great for guys with lower back issues because it takes a lot of the pressure off the back and places it on the legs — which means it’s most suitable for building strong, massive legs.
It also works best for guys with shorter limbs and longer torsos. The one catch is that the sumo deadlift requires a higher level of flexibility around the hips, especially the adductors, since a lot more mobility is needed to get into the correct position compared to conventional pulling. If you can’t get into a proper sumo setup, work on hip flexibility before loading the movement.
Sumo is your best bet if:
- You have lower back problems or a history of back injury
- You have a longer torso and shorter limbs
- You have good hip mobility
- Your goal includes quad and adductor development alongside the posterior chain
Side by Side
| Conventional | Sumo | |
|---|---|---|
| Stance | Shoulder width | Wider than shoulder width |
| Hands | Outside the legs | Inside the legs |
| Range of motion | Longer | Shorter |
| Lower back demand | Higher | Lower |
| Leg demand | Lower | Higher |
| Hip mobility needed | Moderate | High |
| Best for lower back issues | No | Yes |
| Best torso type | Shorter | Longer |
Should You Do Both?
Yes — and many experienced guys do. Using both variations across a training cycle hits the posterior chain from different angles and addresses weaknesses that one variation alone won’t fix.
A common approach is heavy conventional pulling once per week with sumo on a lighter technique day, or simply alternating between them week to week.
You can also add Romanian deadlifts as an accessory movement regardless of which main variant you use — RDLs build hamstring strength and reinforce the hip hinge pattern without the same spinal loading as either pulling variation from the floor.
The Bottom Line
So, both exercises work great for different body parts, which means you should definitely try both and make up your own mind. But if you’re suffering from lower back pain, stick with the sumo deadlift.
Regardless of your preferences, make sure to include deadlifts in your program because they always bring some pretty amazing gains. Just grab a bar with some weight on it, don’t be afraid to experiment a bit, and soon enough you’ll find your ideal deadlift variant that works best with your body type and personal goals.
