Romanian Deadlift

What is the Romanian deadlift?

The Romanian deadlift (RDL) is the highest-yield isolated hamstring exercise and one of the best teaching tools for the hip hinge pattern. Unlike the conventional deadlift, the bar starts at the top and lowers from a standing position; the knees stay bent throughout, and the hips drive the movement. The RDL targets the hamstrings and glutes through a long, productive range of motion.

Who should do RDLs?

Almost every lifter benefits from RDLs. Beginners should learn the RDL before the conventional deadlift; the hip-hinge pattern is the foundation of both, and the RDL teaches it with lighter loads in a safer position. Intermediate and advanced lifters use the RDL as accessory work for hamstring hypertrophy and to build hip-extension strength that supports the conventional deadlift and squat. The RDL is one of the most universally applicable hip-hinge exercises.

How do you program RDLs?

Once or twice per week, typically as accessory work after the squat or conventional deadlift. For hypertrophy: 3 to 4 sets of 8 to 12 reps. The RDL is rarely loaded for true 1-rep max strength; it is an accessory lift that works best in moderate rep ranges where the hamstring stretch and contraction can be felt and controlled. Most trainees can RDL 70 to 85 percent of their conventional deadlift weight for sets of 8 reps.

What is the difference between RDL and stiff-legged deadlift?

The RDL keeps a soft knee bend throughout the lift and emphasizes the hamstrings and glutes. The stiff-legged deadlift locks the knees out completely, which extends the range of motion and emphasizes the lower back along with the hamstrings. The RDL is generally safer and more productive for hamstring hypertrophy; the stiff-legged version has niche applications in advanced strength programs but is rarely the better choice.

Why does the bar need to stay close to the body?

As the bar drifts away from the body, the lever arm on the lower back lengthens and the hip hinge becomes a lower-back movement. The hamstrings stop working efficiently and the lower back takes increasing percentages of the load. Keeping the bar in light contact with the legs throughout the descent and ascent maintains the correct lever and ensures the hamstrings are doing the work the lift is designed to train.

Frequently asked questions

How low should you go?

To the point of strong hamstring stretch without losing flat-back position. For most trainees this is just below the knees; for trainees with excellent hamstring mobility, the bar can travel mid-shin or to the floor. Going lower than your mobility allows breaks form (lower-back rounding) without adding hamstring stimulus; stop where the hamstrings feel maximally stretched but the back stays flat.

Why am I feeling RDLs in my lower back instead of hamstrings?

Three common causes. First, the bar is drifting forward of the body, lengthening the lower-back lever. Second, the lower back is rounding at the bottom, indicating mobility limits or going too low. Third, the hamstrings are weak relative to the lower back, so the back compensates. Address by maintaining bar contact with the legs, limiting depth to flat-back range, and gradually building hamstring strength through repeated sessions.

Can you do RDLs with dumbbells?

Yes, and they are a productive variation. Dumbbell RDLs allow the hands to travel slightly differently, which suits some trainees with shoulder mobility limitations. The total load is lower, but the hamstring stretch and contraction can be more pronounced because the dumbbells can pass closer to the body. Dumbbell and barbell RDLs are interchangeable for most hypertrophy goals.

What is the single-leg RDL?

A unilateral variation where one leg is on the floor and the other extends behind the body during the hinge. Single-leg RDLs train balance and address asymmetries that bilateral RDLs hide. They use much lighter loads (20 to 40 percent of bilateral RDL weight) and produce excellent glute and hamstring stimulus per rep. They are a productive accessory addition to most leg programs.
