Romanian Deadlift: The Hamstring Builder

The Romanian deadlift trades range of motion for tension, making it one of the best hamstring builders there is — if you keep the bar close and the back flat. Here is how.

Romanian Deadlift demonstration

The Romanian deadlift (RDL) is a hip hinge, not a squat and not a full deadlift from the floor — the bar starts at hip height and travels only as far down as your hamstring flexibility allows with a flat back.

How to do it

  1. 1Start standing with the bar — hold it at hip height, feet hip-width apart, knees softly bent.
  2. 2Push your hips back — keeping the bar close to your legs, hinge your hips back while your torso lowers forward.
  3. 3Keep a flat back throughout — your spine should stay neutral — that is what limits how low you go, not your hands touching the floor.
  4. 4Feel the hamstring stretch — lower until you feel a strong stretch in your hamstrings, typically around mid-shin.
  5. 5Drive your hips forward — reverse the movement by pushing your hips forward to standing, squeezing your glutes at the top.

Sets and reps

3–4 sets of 8–12 reps, moving slowly enough to feel the stretch on the way down rather than dropping quickly.

Common mistakes

  • Bending the knees too much. This turns the RDL into a squat and takes tension off the hamstrings. Keep the knee bend soft and constant, not increasing as you descend.
  • Rounding the back to go deeper. Depth should be limited by hamstring flexibility, not by rounding your spine to reach further. Stop where your back would otherwise round.
  • Letting the bar drift forward. A bar that drifts away from your legs turns into a much heavier, less stable lift. Keep it close, brushing your thighs.

Safety note

This exercise puts significant demand on your hamstrings and lower back — start lighter than your regular deadlift weight, even if the movement looks familiar.

Depth is not the goal here — tension is. A shorter range with a flat back beats a deeper one with a rounded spine every time.
