Romanian Deadlift: How to Do It, Muscles Worked and Mistakes to Avoid

The Romanian deadlift (RDL) is a hip-hinge exercise: you push your hips back to lower a weight along your legs, then drive your hips forward to stand tall. It mainly trains your hamstrings and glutes, while your lower back works to hold your spine still. With light dumbbells it suits most beginners, and it builds the strength you use every time you pick something up.

How to do a Romanian deadlift

These steps use dumbbells; a barbell moves the same way.

1. Set up. Stand with your feet hip- to shoulder-width apart, a dumbbell in each hand in front of your thighs, palms facing you.
2. Soften your knees. Unlock them into a slight bend and keep that same bend for the whole rep.
3. Brace. Take a breath, tighten your midsection and draw your shoulders gently back and down.
4. Hinge. Push your hips straight back, as if closing a car door behind you with your rear end. Your chest tips forward and your back stays flat.
5. Lower. Slide the weights down close to your legs until you feel a strong hamstring stretch, usually somewhere between the knees and mid-shin.
6. Stand up. Squeeze your glutes and drive your hips forward, keeping the weights close.
7. Finish tall. Stop with your hips under your shoulders, without leaning back. Reset your breath and repeat.

Form cues

• Feel it in the backs of your thighs, not your lower back.
• Hips go back, not down.
• Look at the floor a few feet ahead so your neck stays in line with your back.
• Breathe in and brace at the top, hold it on the way down, breathe out as you stand.

Muscles worked

The RDL is a hip extension exercise. Your hamstrings and gluteus maximus pull your hips from bent to straight, and they are stretched under load on the way down. Your lower back muscles mostly hold your spine still.

In eight trained men, gluteus maximus activity at a one-rep max on the RDL was not significantly different from the barbell hip thrust, while the back squat drove more front-thigh activity than either (1). In 21 men, the conventional deadlift produced more front-thigh and glute activity than the RDL (2). So the RDL is a hip-dominant lift with relatively little quadriceps work.

A caution: EMG shows how hard a muscle is switched on, and higher activation does not prove more growth. Training studies matter more:

• In 32 young adults, six weeks of either slow-lowering RDLs or Nordic hamstring curls, twice a week, increased hamstring cross-sectional area by about 10%, with no difference between the two (3).
• In 36 untrained people, nine weeks of stiff-leg deadlifts three times a week grew the hamstrings by 7% on average, most of all the semimembranosus, an inner hamstring (4).

Common mistakes

• Squatting the weight down. The knees bend, the hips sink and your thighs take over. Fix: keep your starting knee bend, and practice pushing your hips back to touch a wall a foot behind you.
• Rounding your back to reach lower. Fix: stop where your back stays flat, even if the weights only reach your knees. Range improves with practice.
• Letting the weights drift forward. The farther they hang from your legs, the more your lower back has to hold. Fix: keep them brushing your thighs and shins.
• Leaning back at the top. Fix: finish by squeezing your glutes, ribs down, body in a straight line.
• Going too heavy, too soon. Your grip or form fails first. Fix: use a weight you control for every rep, with one to three reps left in reserve.

Variations: easier and harder

If your back is irritable, a glute bridge loads the same hip muscles with your spine supported on the floor. If your knees are the problem, the RDL itself is usually a good choice, since the knee angle barely changes.

How to do a single-leg Romanian deadlift

1. Hold a dumbbell in the hand opposite your standing leg, with a soft bend in the standing knee.
2. Hinge forward while your free leg reaches straight back, like a seesaw.
3. Keep your hips square to the floor, then drive your hip forward to stand. Touch a wall or chair for balance if you need to.

Of 12 rehab exercises tested in 21 active adults, the single-leg deadlift and single-leg squat produced the highest gluteus maximus activity, plus solid gluteus medius activity (6). In 12 trained men, holding the weight opposite the standing leg raised glute and lower-back activity in a flywheel version, and the authors recommend that position for dumbbells too (7).

Sets, reps and how often

The rep ranges and rest periods below follow the American College of Sports Medicine’s position stand on resistance training (8). The set counts are practical starting points.

The ACSM recommends two to three sessions a week for beginners, and adding 2 to 10% to the load once you can do one or two reps more than your target. The heavy 1 to 6 range is meant for people with roughly six months or more of steady training (8).

Light dumbbells are not a dead end. A meta-analysis of 21 studies found light loads built as much muscle as heavy ones when sets were taken to failure, though heavy loads built more maximal strength (9). That finding earns an A grade in our Evidence Index of health claims. Scheduling matters less: with weekly volume equal, training a muscle once or three times a week grew it about the same (10). For weekly targets, see how many sets per muscle per week.

Romanian deadlift vs deadlift: what is the difference?

A conventional deadlift starts every rep from the floor, with your knees bent more and your hips lower. An RDL starts standing, lowers only as far as your hamstrings allow and never rests the weight on the floor, while your knees stay almost still. So the conventional deadlift is more of a whole-leg lift, with more front-thigh and glute activity (2), while the RDL focuses on your hamstrings and is easier to learn with light weights.

Neither is better overall. To lift the most weight from the floor, train the deadlift. For stronger hamstrings and a simple way to practice the hip hinge, choose the RDL.

The name has a real origin. US weightlifting coach Jim Schmitz writes that Romanian champion Nicu Vlad and his coach demonstrated the lift at his San Francisco gym in 1990, and with no name for it, Schmitz suggested Romanian deadlift (11).

Which is better, RDL or stiff-leg deadlift?

The stiff-leg deadlift (SDL) keeps the legs straighter, and definitions vary between coaches. In ten experienced bodybuilders lifting 80% of their max, the RDL produced more activity in the semitendinosus, an inner hamstring, while the SDL produced more glute activity on the way up (5). That is one small lab study. Choose the version you can do with a flat back, and remember that straighter legs demand more hamstring flexibility.

Do RDLs actually grow glutes?

They train the glutes hard, but the direct evidence is thin. The glutes are one of the two main movers, and at maximal loads their activity rivals the hip thrust (1). A 2025 meta-analysis found a moderate effect of hip-extension training on gluteus maximus size, with hip thrusts, parallel or deeper squats, the leg press and kneeling hip extensions all working (12). We found no trial that measured glute growth from RDLs alone, while hamstring growth from RDLs and stiff-leg deadlifts is documented (3, 4).

In practice, pair RDLs with a squat such as the goblet squat and a bridge or hip thrust to cover your glutes from every angle. The technique and programming are the same for women and men.

Is it safe? Who should be careful

For most healthy adults, a Romanian deadlift with sensible weights and a flat back is safe. A strong hamstring stretch and next-day soreness are normal. Stop if you feel sharp pain, pain that shoots down a leg, or numbness or tingling.

• Low back pain. Deadlifts can help some people, not all. In 35 people with mechanical low back pain who did eight weeks of deadlift training supervised by a physical therapist, those who started with less pain and disability and better hip and back muscle endurance benefited most (13). If your back hurts now, start with a physical therapist and our lower back pain exercises.
• A recent hamstring strain. RDLs are often used in hamstring rehab, but let your clinician decide when to load the stretch.
• High blood pressure, heart disease or osteoporosis. Holding your breath while straining briefly raises blood pressure, so breathe out as you stand. Ask your doctor or a physical therapist before lifting heavy.
• Pregnancy. The American College of Obstetricians and Gynecologists says that without complications, exercise in pregnancy is safe and desirable, though routines may need adjusting (14). Go lighter and skip the single-leg version as your balance shifts, and check with your obstetric care provider.

See a physical therapist or doctor if pain lasts more than a few days, worsens from session to session, or changes how you move. Read our medical disclaimer.

Watch it done

Our video 5 dumbbell exercises for a full-body workout shows the dumbbell Romanian deadlift as its second move, step by step and then in a 40-seconds-on, 20-seconds-off follow-along. Its cues match ours: a flat back, hips pushed back as if closing a car door, lowering to a deep hamstring stretch, then squeezing your glutes to stand.
