Dumbbell Cross Body Romanian Deadlift

A single-leg Romanian deadlift with the dumbbell moving across the body — emphasizing the working glute and hamstring through a long hinge.

How to do it

  1. Hold one dumbbell in one hand and stand on the leg opposite that hand with a slight knee bend.
  2. Brace your core and pull your shoulder blades down so the working side stays square at the start.
  3. Hinge at the hips, sending your free leg straight back while the dumbbell travels across toward your standing foot.
  4. Lower until your torso is roughly parallel to the floor and you feel a strong stretch in your working hamstring.
  5. Pause at the bottom, keeping your hips square and back flat, without letting the working hip open up.
  6. Drive your working heel into the floor and stand tall, squeezing your glute hard at the top of the rep.

Key technique cue

Keep the hips square to the floor; reach down only as far as your back stays flat.

Common mistakes

  • Opening up the hip of the free leg, which turns the exercise into a rotation instead of a clean hinge.
  • Rounding the lower back at the bottom because the hamstrings can't yet reach the dumbbell.
  • Bending the standing knee too much, which turns the exercise into a single-leg squat instead of a hinge.
  • Lifting the dumbbell with the lower back instead of pushing the floor away through the working glute.

Benefits

  • Builds single-leg glute and hamstring strength with a long, loaded stretch.
  • Trains balance and anti-rotation through the trunk under a real load.
  • Exposes and corrects posterior-chain strength differences between sides.

About the exercise

The Dumbbell Cross Body Romanian Deadlift is a single-leg hinge where the dumbbell is held in the hand opposite the working leg and travels across the body on the way down. The cross-body load creates a stronger pull into the working glute and hamstring, while the trunk is forced to resist rotation all the way down. It is a high-value exercise for hypertrophy and athletic conditioning when you need serious glute and hamstring work without a barbell. It also suits rehab-adjacent and movement-quality work when you are rebuilding single-leg control.
