Sumo vs conventional deadlift: which is best?

Walk into any powerlifting meet and you’ll see both styles on the platform. Ed Coan pulled conventional. Yury Belkin pulls sumo. Both are among the greatest deadlifters in history.

The debate over which is “better” misses the point. They’re different tools. Your job is figuring out which one fits your body and goals. For an overview of all the lifts in the program, see the exercise guide.

The Key Differences

Conventional deadlift:

• Feet hip-width apart
• Hands outside your legs
• More forward lean at the start
• Longer bar path
• Emphasizes back and hamstrings

Sumo deadlift:

• Feet wide (near the plates)
• Hands inside your legs
• More upright torso
• Shorter bar path
• Emphasizes quads and adductors

A 2019 study in the International Journal of Sports Medicine found total muscle activation was nearly identical between styles when lifters used their preferred stance. The difference is which muscles do the most work, not whether the lift is easier.

Body Type Considerations

Torso-to-Leg Ratio

Long torso, short legs: Conventional often feels better. Your back position is less extreme.

Short torso, long legs: Sumo might suit you. The wide stance lets you get your hips closer to the bar without folding over.

Hip Structure

Wide hips and good hip mobility: Sumo allows you to sink into position comfortably.

Narrow hips or limited mobility: Conventional requires less extreme hip angles.

Arm Length

Long arms: Conventional benefits you — less bending required to reach the bar.

Short arms: Sumo’s upright torso helps compensate.

These are tendencies, not rules. Plenty of long-legged lifters pull big conventional and plenty of short-armed lifters dominate in sumo.

When Conventional Makes Sense

You’re a beginner: Conventional teaches the fundamental hip hinge pattern. This transfers to rows, RDLs, kettlebell swings, and picking things up in real life.

You want maximum back development: Conventional places higher demands on your erectors and lats. If back thickness is a priority, conventional delivers.

Your sport requires it: Strongman competitions usually mandate conventional. Many athletes need the carryover to pulling movements in their sport.

You lack hip mobility: Sumo requires significant hip abduction and external rotation. If you can’t comfortably get into the wide stance, don’t force it.

When Sumo Makes Sense

Your conventional deadlift stalls: Sometimes switching styles bypasses a stubborn plateau. Different leverages challenge different weak points.

You have back issues: The more upright torso in sumo reduces lower back stress. If conventional hurts despite good form, sumo might let you keep deadlifting.

Your body prefers it: Some people just pull more in sumo. Their anatomy makes the wide stance mechanically advantageous. If you’re significantly stronger sumo, use it.

You compete in powerlifting: If sumo lets you lift more, and the rules allow it, there’s no reason not to use it in competition.

Strength Differences

Research shows trained lifters can typically pull similar maxes in either style after practicing both. Beginners usually pull more conventional because they’re more familiar with the movement pattern.

A 2020 analysis across multiple studies found:

• Average 1RM was within 5% between styles for experienced lifters
• Conventional pulled slightly higher in lifters who hadn’t practiced sumo
• Sumo showed less low back loading at equivalent weights

The “sumo is easier” argument doesn’t hold up. The shorter bar path is offset by increased demands on hip mobility and quad strength off the floor.

Muscle Activation Breakdown

Conventional emphasizes:

• Erector spinae (lower back)
• Hamstrings
• Glute max
• Upper back (lats, traps)

Sumo emphasizes:

• Quadriceps
• Adductors (inner thigh)
• Glute max
• Hip external rotators

Both work the grip, core, and posterior chain. You’re not missing major muscle groups with either style.

How to Test Which Suits You

Week 1-2: Pull conventional only. Work up to a challenging but clean set of 5. Note how it feels — where you struggle, where you’re strong.

Week 3-4: Pull sumo only. Same protocol. Compare.

Assessment questions:

• Which style lets you maintain better back position?
• Which feels more natural off the floor?
• Which lockout is smoother?
• Any pain or discomfort in either style?
• Which are you stronger in after equal practice?

Give both styles fair time. Most people default to conventional because it’s what they learned. Sumo might surprise you after a few weeks of practice.

For 5x5: Stick With One

The 5x5 program calls for one deadlift set per workout. Pick a style and stick with it.

Switching between styles workout-to-workout prevents you from getting good at either. You’re building a movement pattern, not just moving weight. Consistency matters.

If you want to eventually train both, master one first. After 6+ months of consistent progress, you can add the other style as occasional variation or assistance work.

The Bottom Line

Neither style is inherently better. Sumo isn’t cheating. Conventional isn’t superior.

Your anatomy, mobility, goals, and preferences determine which works for you. Try both seriously, pick one, and commit to getting strong at it.
