Romanian Deadlift Strength Standards

The conventional deadlift starts from the floor, uses a concentric pull with significant quadriceps involvement, and returns the bar to the floor each rep. The Romanian Deadlift (RDL) starts from standing, emphasizes the eccentric (lowering) phase, maintains a slight knee bend throughout, and reverses at the point of maximal hamstring stretch \u2014 typically mid-shin to just below the knee. The bar does not touch the floor between reps.

Because of the reduced quadriceps contribution and the emphasis on eccentric control, the RDL typically uses 73\u201383% of conventional deadlift load for men (increasing with experience level) and approximately 75% for women. StrengthLevel.com comparison data (1.15M RDL lifts vs 22.9M CDL lifts) confirms these ratios. Do not use these standards interchangeably.

Lower the bar until you feel a strong stretch in the hamstrings, typically somewhere between mid-shin and just below the knee. There is no single correct depth for everyone \u2014 hamstring flexibility, femur length, and hip anatomy all affect range of motion.

The key indicators of appropriate depth are: (1) you feel a distinct hamstring stretch, (2) your lower back remains flat or slightly arched (no rounding), and (3) the bar stays in contact with the legs throughout. Forcing the bar lower than your flexibility allows leads to lumbar flexion, which changes the exercise into a stiff-leg deadlift and increases spinal load. Consistent range of motion across sets is more important than absolute depth.

Yes, though many people use the terms interchangeably. In the Romanian Deadlift, the knees maintain a slight, consistent bend (approximately 15\u201320\u00b0), the hips push back, and the bar stays very close to the legs. The range of motion is limited by the hamstring stretch. In the stiff-leg deadlift (SLDL), the knees are nearly locked, the bar may drift forward away from the body, and the range of motion often extends further toward the floor, placing greater stress on the lower back and less emphasis on hip-hinge mechanics.

McAllister et al. (2014, J Strength Cond Res 28(6):1573\u20131580) demonstrated that the RDL and SLDL activate the hamstrings similarly but the RDL places less demand on the erector spinae due to the more posterior weight distribution and hip-dominant mechanics. These standards apply to the RDL specifically \u2014 results from a stiff-leg deadlift are not directly comparable.

Grip can become the limiting factor before the posterior chain is fully challenged, especially at the intermediate level and above. Using lifting straps or a mixed (over-under) grip is a practical option when the goal is to maximize hamstring and glute loading.

If you use straps, your effective hamstring loading will be higher than with a double-overhand grip. For these standards, use whichever grip allows you to complete the set with strict RDL form. Be consistent across assessments \u2014 switching grip method between tests reduces comparability.

The RDL and hip thrust are complementary, not interchangeable. The RDL emphasizes the hamstrings in a lengthened (stretched) position and trains the hip-hinge pattern under axial load. The hip thrust emphasizes the glutes at peak hip extension with a shorter range of motion and allows heavier loading due to the mechanical advantage.

At the intermediate level for a 180 lb male, the StrengthRegimen RDL standard is 252 lb while the hip thrust standard is 279 lb. The hip thrust is higher because its short ROM and supported back position allow greater absolute load. Both exercises are valuable for posterior chain development, and most strength programs benefit from including both.
