If the RDL had a slogan it would be ‘simple, but not easy’. If performed poorly, it can lead to pain or tension in the lower back, knees and hamstrings. But if you master the form, you’ll learn a versatile exercise that builds functional strength, flexibility, and sculpted glutes that will serve you well in many future workouts.
Halter RDL 101: what it works and benefits
RDLs aren’t just for leg day. They are actually full-body movements that train coordination, stability and control. Here’s what works hard if you do it 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 motion. This improves your flexibility and reduces the risk of injuries.
- Glutes – When you push your hips forward at the top of the lift, your glutes work hard to bring you back up. Over time, this “hinging” movement can help strengthen, shape, and grow your glutes.
- Lower back – During an RDL, the erector spinae muscles that surround your spine work to keep it stable.
- Core – Throughout the movement you contract your abdominal muscles and obliques, which support both your spine and your daily balance.
As a bonus, holding dumbbells through their full range of motion means your forearm and grip strength will improve.
Activating these key areas provides several benefits that go far beyond building muscle:
- Muscle growth and toning – Yes, it’s true: RDLs can make your glutes grow. The key is to gradually increase your weight or reps over time to ensure you’ve mastered the correct form. By engaging your glutes at the start of each rep, you’ll stimulate muscle growth and improve definition over time.
- Joint-friendly strength training – Because RDLs have a smaller range of motion than traditional deadlifts, the emphasis is on slow, controlled movements rather than the heavy loads. If you maintain proper form, RDLs are easier on your knees while still providing significant strengthening results.
- Better hip mobility – The hinging motion of RDLs helps 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 can promote a more upright, confident posture.
RDL vs. Deadlift: What’s the Difference?
Both Romanian deadlifts and conventional deadlifts strengthen the posterior chain. However, their operation and goals differ:
- Traditional deadlifts – These start from the floor and require you to bend your knees dramatically. It is a strength movement that is ideal for strengthening the entire body and teaching your body to lift heavy loads.
- Romanian deadlifts (RDLs) – These start from a standing position and keep the knees slightly bent throughout the movement. The emphasis here is on lowering the weight (eccentric movement), which increases time under tension and improves flexibility of 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 Barbell RDL
Properly performing the Romanian barbell deadlift comes down to alignment, control and intention. Here’s how to complete one step by step:
- Start in a standing position – Start with your feet hip-width apart and your knees gently bent. You can start with dumbbells on the floor or hold one in each hand. (If you’re holding your dumbbells to start, gently rest them on the front of your quads to start, with palms facing your legs in an overhand grip.)
- Engage your core and control your posture – Pull your shoulder blades down your back. Engage your core, keep your chest and chin up and lengthen your spine.
- Start the hip hinge – Keep a gentle bend in your knees with your spine long and begin to push your hips back, reaching toward the floor. To master your hinge, it can help to imagine using your hips to close a door behind you. (When you hold your dumbbells, they should almost slide down the front of your legs as you bend forward.)
- Lower the dumbbells – Continue lowering your torso until you start to feel a pull in your hamstrings and you can’t move your hips any further back. Keep your back flat and your head in line with your spine.
- Drive through your glutes to stand – Re-engage your core, press your feet into the ground and push through your hips to stand. Once you reach the top, squeeze your lats and glutes.
- Repeat, focusing on control – Continue with the desired number of repetitions, focusing on slow, controlled movements 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 dumbbells first to master your hip hinge. With an expert hip hinge, your back remains flat, but your knees are not excessively bent. You can also start with lighter dumbbells and build up from there.
Common RDL mistakes with dumbbells: tips for beginners
The RDL may look simple, but it is surprisingly technical. Even small mistakes can reduce its effectiveness, strain your hamstrings or lower back, or otherwise disrupt 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
If you bend your knees excessively, your RDL can turn into a squat. This shifts the focus from your hamstrings and glutes, the main targets of the exercise.
To avoid this, make sure your knees are gently bent – just enough so that they remain unlocked. This will help you hinge from your hips.
Round your back
By rounding your spine, you lose tension in your posterior chain, which puts you at risk for injury.
Try to maintain a neutral spine during the exercise. It may help to imagine that you are balancing something on your back, all the way from your head to your tailbone.
Moving too fast
A major trend in strength training is rushing through reps. Slowing down improves the mind-muscle connection, which some research shows can give you more bang for your buck during workouts.
As a solution, you can simply focus on moving slowly. Pay attention to a controlled descent and re-engage your core, shoulders and glutes when you return to standing.
Float the dumbbells forward
If your weights drift too far from your legs, your lower back will feel the strain.
To solve the problem, hold your dumbbells close to your body. They should almost brush your thighs and shins when you bend over.
Skip the warm-up
RDLs strengthen your hamstrings by introducing time under tension. If yours are tight, it can make them uncomfortable or limit your range of motion.
To solve this problem, warm up with dynamic stretches such as hip circles, leg movements or good morning exercises (using only your body weight) to prepare your muscles for the load.
4 RDL variations to try
Once you’ve mastered the dumbbell RDL, you can spice it up even more by trying some of these RDLs with a twist:
- Single-leg dumbbell RDL – This variation trains balance and stability while training your legs in isolation. Hold one or two dumbbells and hinge forward on one leg while your other extends behind you. Or you can use a bench to support your non-working leg.
- Staggered stance RDL – This one is a killer for beginners transitioning to the single-leg version. Place one foot slightly behind the other, keeping most of your weight on your front leg. Hinge down as usual and press your weight into the heel of your standing leg.
- Dumbbell RDL – If you are comfortable with dumbbells, you can try a barbell for a heavier load. The movement pattern remains static, but by using a bar you can increase your weight and challenge your posterior chain even more.
- RDL shortage – Standing on a small step or platform increases your range of motion and the involvement of your hamstrings. In the beginning, 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.
