Single-Leg Dumbbell Romanian Deadlift (Deficit)
- Advanced
- Dumbbell
The deficit version stands the working foot on a low platform so the dumbbell can travel below the level of the foot. Everything else matches the standard single-leg RDL: soft standing knee, free leg extending behind, hips level, spine long, dumbbell tracking down the standing leg. The extra couple of inches load the hamstring at a longer muscle length, which is where hinge variations do most of their work. The turnaround belongs at the point where hamstring length stops the descent, and a deficit simply moves that point lower.
How to do the Single-Leg Dumbbell Romanian Deadlift (Deficit)
- Set a stable platform one to three inches high and stand on it with one foot.
- Hold a dumbbell and shift your weight onto the standing leg.
- Soften the standing knee and set your shoulders back.
- Push the hip back and let the free leg extend behind you.
- Lower the dumbbell past the level of the platform, keeping the hips level.
- Drive the hip forward to stand, then finish the set and switch sides.
Muscles worked
- Primary:
- Hamstrings and Glutes
- Secondary:
- Core and Calves
Why train it
- Adds hamstring range at the bottom without adding external load.
- Trains the hamstring at long muscle length on one leg at a time.
- Gives a progression step for users who have outgrown the flat version.
Common mistakes
- Using a platform so tall that the back rounds before the hamstring reaches its limit.
- Letting the free hip rotate open, which turns the hinge into a rotation.
- Standing on an unstable riser, which makes balance rather than the hamstring the limit.
- Keeping the same load as the flat version, which is heavier through the added range.
