How to Do a Romanian Deadlift (RDL): Proper Form Guide

To do a Romanian deadlift, hold a barbell at the top of a deadlift, soften your knees slightly, then push your hips straight back to lower the bar down the front of your legs until you feel a deep stretch in your hamstrings — then drive your hips forward to stand tall. The RDL is a hip hinge, not a squat and not a back-rounding "stiff-leg" lift. Master that hinge and you have one of the most effective hamstring and glute builders in the gym.

The most common mistake is treating it like a squat or a toe-touch. This guide breaks down the correct romanian deadlift technique step by step, shows you how to find your depth, and explains how the RDL differs from a conventional deadlift.

Muscles worked: the best hamstring builder

The RDL trains the entire back of your body, but it specializes in the hamstrings.

Hamstrings (primary): The lift loads your hamstrings under a long, controlled stretch — exactly the stimulus that builds size and resilient, injury-resistant tissue.
Glutes: Standing back up is hip extension, which is the glutes' main job. The RDL is one of the cleanest ways to overload them.
Spinal erectors and upper back: Your lower back and lats work isometrically to keep your spine neutral and the bar pinned to your body.

Because the knees stay relatively fixed, the hamstrings can't "cheat" by helping at the knee — they're forced to do their second job, extending the hip, against a long lever. That's why a properly executed hamstring deadlift like the RDL outperforms most machine curls for building the posterior chain.

How to do a Romanian deadlift, step by step

Good rdl form comes down to one idea: move the bar by moving your hips, not by bending your spine.

The setup

Stand with feet hip-width apart, holding a loaded barbell at the top of a deadlift, arms straight, bar resting against your upper thighs.
Brace your core as if about to be lightly punched, and pull your shoulders down and back so your lats are tight.
Unlock your knees so they're "soft" — a slight bend, then hold that bend. You do not bend them further during the rep.

The descent: hips back, bar dragging the thighs

Initiate by pushing your hips straight back toward the wall behind you, as if closing a car door with your butt.
Let your torso tip forward as a single rigid unit. Your spine stays neutral the whole way.
Keep the bar in contact with your legs, dragging it down your thighs and shins. If it drifts away from your body, the load shifts onto your lower back.
Lower until you feel a strong stretch in your hamstrings — for most people that's somewhere between mid-shin and just below the knee.

The drive back up

Reverse the motion by driving your hips forward into the bar.
Squeeze your glutes hard at the top and stand tall — don't lean back or overextend your lower back.
The bar finishes back against your thighs, ready for the next rep.

A useful cue: your hips and the bar should reach the top at the same moment. If your chest pops up first and the bar lags, you're using your back instead of your hips.

Finding your depth: stretch, not the floor

A Romanian deadlift does not need to reach the floor. Your range of motion is set by your hamstring flexibility, not by touching a plate to the ground.

Lower only as far as you can while keeping a neutral spine. The moment your lower back starts to round, you've gone past your usable range.
Most lifters bottom out between just below the knee and mid-shin. Long-legged or less mobile lifters may stop higher — that's fine.
Chasing extra depth by rounding your back doesn't add hamstring tension; it just shifts load onto your spine. Stop at your honest stretch limit and own that range.

As mobility improves over weeks, your depth will naturally increase. Let it come to you.

RDL vs conventional deadlift vs stiff-leg

The rdl vs deadlift question trips up a lot of beginners. They look similar but train different things.

Conventional deadlift: Starts from a dead stop on the floor, with more knee bend and a bigger contribution from the quads and hips. It's a maximal full-body strength lift. See the conventional barbell deadlift for that pattern.
Romanian deadlift: Starts from the top, knees stay softly bent and fixed, and the bar never touches the floor. It biases the hamstrings and glutes through a controlled eccentric stretch.
Stiff-leg / straight-leg deadlift: Keeps the knees nearly locked and often does pull from the floor, putting the hamstrings on an even longer stretch — but it's harder on the lower back and demands more flexibility.

When to use each: Train the conventional deadlift for raw pulling strength. Use the RDL as your primary hamstring and glute hypertrophy builder. Save stiff-leg variations for when your hinge and mobility are already solid.

Common RDL faults and fixes

Squatting it down. If your knees travel forward and your hips drop, you've turned it into a squat. Fix: lock in a soft knee angle at the start and think "hips back," not "knees bend."
Rounding the back. Usually means you're going too deep or losing your brace. Fix: shorten your range, re-brace your core, and keep your chest proud through the descent.
Bar drifting forward. The bar swinging away from your legs overloads your spine and kills hamstring tension. Fix: actively pull the bar into your thighs and keep your lats tight so it drags down your legs.
Hyperextending at the top. Leaning back and arching at lockout stresses the lower back. Fix: finish tall with a hard glute squeeze and a stacked, neutral spine.

Loading, reps, and how the RDL complements your deadlift

The RDL responds best to controlled, moderate loading — this is a feel-the-muscle exercise, not an ego lift.

Rep range: 6–12 reps per set works well for hamstring and glute growth. Lower the bar with a deliberate 2–3 second tempo to maximize the stretch.
Sets and frequency: 2–4 working sets, once or twice a week, is plenty for most lifters.
Progression: Add a small amount of weight or a rep when you can hit the top of your range with clean form — the foundation of progressive overload.

As an accessory, the RDL directly strengthens the hamstrings and glutes that drive lockout on your conventional deadlift, so building them here tends to carry over to a bigger pull. Track your RDL alongside your main lifts so you can see the strength transfer over time.

Frequently asked questions

Is the Romanian deadlift better than the conventional deadlift for hamstrings?

For hamstring and glute growth specifically, yes — the RDL keeps constant tension on the posterior chain through a long stretch. The conventional deadlift is the better choice for overall pulling strength and full-body power.

How low should I go on a Romanian deadlift?

Only as low as your hamstring flexibility allows while keeping a neutral spine — usually between just below the knee and mid-shin. Stop the moment your lower back starts to round; you don't need to reach the floor.

Should my knees be bent or straight in an RDL?

Softly bent and fixed. Set a slight knee bend at the start and hold it the entire rep. Bending the knees further turns the lift into a squat; locking them straight makes it a stiff-leg deadlift.

Why does my lower back get sore instead of my hamstrings?

Almost always because the bar drifts away from your legs or your back rounds. Keep the bar dragging against your thighs, brace hard, and shorten your range until you feel the work in your hamstrings, not your spine.

How much weight should I use on Romanian deadlifts?

Start lighter than your conventional deadlift — the RDL is about controlled stretch and tension. Pick a load you can move for 6–12 clean reps with a slow descent, then add weight gradually as your form holds.
