The Romanian Deadlift (RDL) is a highly effective exercise that emphasizes the hip-hinge movement pattern, which is fundamental to athletic performance and overall strength. This lift is distinct from the conventional deadlift because it focuses on a controlled eccentric (lowering) phase, starting from a standing position rather than the floor. Using a barbell allows for heavy loading, which is a primary driver for muscle growth and strength development. The barbell RDL is a compound movement targeting the entire posterior chain.
Target Muscles and Benefits
The barbell RDL primarily targets the posterior chain, the group of muscles running along the back of the body. The hamstrings, specifically the hip-extending portions, and the gluteus maximus are the main muscles responsible for the movement. These muscles work together to control the descent and powerfully drive the hips forward during the ascent. The spinal erectors, also known as the lower back muscles, work secondarily to maintain a rigid and neutral spine throughout the entire range of motion.
Strengthening the posterior chain through RDLs improves athletic movements like sprinting, jumping, and explosive hip extension. The exercise strengthens the hamstrings through an extended range of motion under load, which helps increase the muscle-tendon unit’s resilience and reduces the risk of strains. The consistent engagement of the core muscles also helps stabilize the torso, translating into improved posture and spinal stability. Furthermore, the RDL is an excellent tool for increasing muscle mass in the glutes and hamstrings, as the eccentric focus places the muscle fibers under significant stretch and tension.
Setup and Starting Position
To begin the barbell RDL, first unrack the bar or deadlift it to a standing position, ensuring your feet are positioned about shoulder-width apart. Establish a firm grip on the bar just outside of your legs, using either a double overhand grip or a mixed grip for heavier loads to prevent the bar from slipping. Your knees should have a soft, slight bend that remains relatively constant throughout the movement. The initial posture must be upright, with the chest lifted high and the shoulders pulled back and down to engage the upper back muscles, which helps keep the bar close to the body.
Before initiating the movement, take a deep breath to brace the core, locking the ribcage down over the pelvis to create a cylinder of tension around the torso. This bracing action is necessary to maintain a neutral spine angle and prevent the lower back from rounding. The barbell should rest against the thighs, and the chin should be slightly tucked to keep the neck in alignment with the rest of the spine.
Executing the Movement
The dynamic phase of the RDL begins by initiating the hip hinge, which means actively pushing the hips backward as if reaching for a wall behind you. This movement, not a downward squat, is the defining characteristic of the RDL, and it is crucial to keep a neutral spine throughout the descent. As the hips travel backward, the torso naturally pivots forward, ensuring the barbell travels down the front of the legs, staying close to the body at all times. Maintaining this close bar path minimizes stress on the lower back by keeping the weight’s leverage close to the hip joint.
The descent continues until a deep stretch is felt in the hamstrings, or just before the lower back position is compromised by rounding. The depth will vary based on individual hamstring flexibility, but the bar will typically stop somewhere between mid-shin and just below the knees. The knees should maintain their slight bend, but no further significant knee flexion should occur, which differentiates the RDL from a squat. The eccentric (lowering) portion should be controlled and slow, often taking two to three seconds to maximize time under tension.
To complete the repetition, drive the hips forward powerfully while contracting the glutes and hamstrings. The movement should feel like an aggressive hip extension returning the torso to the upright starting position. Avoid hyperextending the lower back at the top; instead, focus on finishing the movement by squeezing the glutes fully.
Avoiding Common Form Errors
A frequent error is allowing the lower back to round, which shifts the stress away from the glutes and hamstrings and onto the spinal ligaments. This indicates the weight is too heavy or the lifter is going too low past their hamstring mobility limit. To correct this, reduce the weight and stop the descent the moment the neutral spinal position is about to break.
Another common mistake is “squatting” the movement by bending the knees too much instead of pushing the hips back. Allowing the barbell to drift away from the legs places excessive horizontal leverage on the lower back. Correct this by actively engaging the lats and thinking about dragging the bar up and down the legs. The movement concludes when the hips are fully extended and the body is standing tall, so resist the urge to hyperextend the spine at the top of the lift.
