For a lifting move that strengthens your lower body and back while improving flexibility, you can’t go wrong with the dumbbell RDL (Romanian deadlift). Best of all, you don’t have to be an Olympic lifter like its namesake, Nicu Vlad, to add it to your routine.
If the RDL had a tagline, it might be “simple, but not easy.” Performed poorly, it can lead to soreness or strain in the lower back, knees, and hamstrings. But master the form, and you’ll learn a versatile exercise that builds functional strength, flexibility, and sculpted glutes, serving you well in many workouts to come.
Dumbbell RDL 101: What it Works and Benefits
RDLs aren’t just for “leg day.” They’re actually a full-body movement that trains coordination, stability, and control. Here’s what’s working hard when you execute correctly:
- Hamstrings – Hamstrings are the main targets of an RDL. By lifting and lowering your dumbbells, this move strengthens the backs of your legs through a lengthening, or eccentric, movement. This will improve your flexibility by reducing your risk of injury.
- Glutes – When you drive your hips forward at the top of the lift, your glutes work hard to bring you back upright. Over time, this “hinging” movement can help strengthen, shape, and grow your glutes.
- Lower back – During an RDL, the erector spinae muscles that girdle your spine work to keep it stable.
- Core – Throughout the movement, you’ll engage your abdominals and obliques, which support your spine as well as your day-to-day balance.
As a bonus, holding dumbbells through the complete range of motion means your forearm and grip strength will improve.
Activating these key areas offers various benefits that go well beyond building muscle:
- Muscle growth and toning – Yes, it’s true: RDLs can grow your glutes. The key is to gradually increase your weight or reps over time, ensuring you’ve mastered the proper form. By engaging your glutes at the top of each rep, you’ll stimulate muscle growth and improve definition over time.
- Joint-friendly strength-training – Because RDLs have a narrower range of motion than traditional deadlifts, the emphasis is on slow, controlled movement rather than the heavy load. If you maintain proper form, this makes RDLs easier on your knees— while still offering considerable strengthening results.
- Better hip mobility – The hinging motion of RDLs helps to open tight hips, encouraging proper movement mechanics in other exercises and daily life.
- Improved posture – By strengthening the posterior chain, RDLs help counteract the effects of sedentary activities (e.g. sitting at a desk). In this way, it may encourage a more upright, confident posture.
RDL vs. Deadlift: What’s the Difference?
Both the Romanian deadlifts and conventional deadlifts strengthen the posterior chain. However, their mechanics and goals differ:
- Traditional deadlifts – These start from the floor and require you to bend your knees dramatically. It’s a power movement ideal for building total-body strengthening and teaching your body to lift heavy loads.
- Romanian deadlifts (RDLs) – These begin from a standing position and maintain a slight bend in the knees throughout the move. The focus here is on lowering the weight (eccentric movement), which increases time under tension, improving flexibility in the hamstrings and glutes.
Both moves are fantastic and can be a dynamic part of any complete workout routine. However, the RDL’s emphasis on control makes it a reliable tool for building strength while learning proper hip-hinge form.
How to Nail Your Form on a Dumbbell RDL
Performing the dumbbell Romanian deadlift correctly comes down to alignment, control, and intention. Here’s how to complete one, step by step:
- Start in a standing position – Begin with your feet hip-width apart, keeping a soft bend in your knees. You can either start with dumbbells on the floor or holding one in each hand. (If you’re holding your dumbbells to start, gently rest them on the front of your quads to start, palms facing your legs in an overhand grip.)
- Engage your core and set your posture – Pull your shoulder blades down your back. Engage your core, keep your chest and chin lifted, and lengthen your spine.
- Initiate the hip hinge – Keeping a soft bend in your knees with your spine long, begin to push your hips back, reaching down toward the floor. To master your hinge, it can help to imagine you’re using your hips to close a door behind you. (If you’re holding your dumbbells, they should almost skim the front of your legs as you bend forward.)
- Lower the dumbbells – Keep lowering your torso until you start to feel a pull in your hamstrings, and you can’t take your hips back any further. Keep your back flat and your head aligned with your spine.
- Drive through your glutes to stand – Engage your core again, drive your feet into the floor, and push through your hips to come to standing. Once you get to the top, squeeze through your lats and glutes.
- Repeat, focusing on control – Continue with your desired number of reps, focusing on slow, controlled motions rather than rushing to complete them. With RDLs, the quality of your form will yield better results than the quantity of your reps.
If you’re brand new to RDLs, consider practicing them without the dumbbells first to master your hip hinge. In an expert hip hinge, your back remains flat, but your knees won’t be overly bent. Alternatively, you can start with lighter dumbbells and build from there.
Common Dumbbell RDL Mistakes: Tips for Beginners
The RDL may look simple, but it’s surprisingly technical. Even small errors can reduce its effectiveness, strain your hamstrings or lower back, or otherwise interfere with your form.
With all that in mind, let’s take a look at five common mistakes and how to fix them.
Bending the Knees Too Much
Bending your knees excessively can turn your RDL into a squat. This shifts the focus away from your hamstrings and glutes—the exercise’s main targets.
To avoid this, make sure to keep a soft bend in your knees—just enough so that they remain unlocked. This will help you hinge from your hips instead.
Rounding Your Back
Rounding your spine causes you to lose tension in your posterior chain, putting you at risk of injury.
Aim to keep a neutral spine throughout the exercise. It can help to imagine you’re balancing something lying on your back, all the way from your head to your tailbone.
Moving Too Quickly
A major tendency in weight training is to rush through reps. When you slow down, it enhances the mind-muscle connection, which some research shows can get you more bang for your buck during workouts.
As a fix, simply focus on moving slowly. Pay attention to a controlled descent and re-engaging your core, shoulders, and glutes when you return to standing.
Letting the Dumbbells Drift Forward
If your weights drift too far away from your legs, your lower back will feel the strain.
To fix the issue, keep your dumbbells close to your body. They should nearly graze your thighs and shins as you bend down.
Skipping the Warm-Up
RDLs strengthen your hamstrings by introducing time under tension. If yours are tight, it can make them feel uncomfortable or slash your range of motion.
To fix this issue, be sure to warm up with dynamic stretches like hip circles, leg swings, or good mornings (using only bodyweight) to help prepare your muscles for the load.
4 RDL Variations to Try
Once you’ve mastered the dumbbell RDL, spice things up by trying some of these RDLs with a twist:
- Single-leg dumbbell RDL – This variation trains balance and stability while working your legs in isolation. Holding one or two dumbbells, hinge forward on one leg while your other one extends behind you. Or, you can use a couch to prop up your non-working leg.
- Staggered stance RDL – This one’s a killer for beginners transitioning to the single-leg version. Place one foot slightly behind the other, keeping most of your weight in your front leg. Hinge down as usual, pressing your weight down on the heel of your standing leg.
- Barbell RDL – If you’re confident with dumbbells, you can try a barbell for a heavier load. The movement pattern stays static, but using a bar allows you to increase your weight and challenge your posterior chain even more.
- Deficit RDL – Standing on a small step or platform will increase your range of motion and hamstring engagement. At first, it’s best to keep your weights light—this one is all about depth and control.
Introducing one or two of these variations into your routine can keep your body guessing as you target your muscles from different angles.
