Single Arm Dumbbell Row

A unilateral back exercise performed with one knee and hand on a bench, targeting the lats, rhomboids, and biceps. The bench takes the lower back out of the equation, so the working side of your back can be loaded hard and heavy in isolation. It is the standard fix for side-to-side back imbalances and often the heaviest row in a program.

Technique

How to Do the Single Arm Dumbbell Row

  1. Place your left knee and left hand on a bench, right foot planted on the floor.
  2. Hold a dumbbell in your right hand, arm hanging straight down, back flat and level.
  3. Row the dumbbell up toward your hip, driving the elbow back past your ribs.
  4. Squeeze the lat and shoulder blade at the top for a beat.
  5. Lower under control until the arm hangs fully stretched.
  6. Finish the set, then mirror the setup for the other side.

Do This

Form Cues

  • Set one knee and one hand on the bench with the back flat and level.
  • Row the dumbbell toward your hip, not straight up to the shoulder.
  • Let the arm hang fully at the bottom to stretch the lat.
  • Keep your shoulders and hips square to the floor. The dumbbell moves, the torso does not.

Avoid This

Common Mistakes

  • Rotating the torso to lift heavier weight.
  • Rowing with the elbow flared wide.
  • Letting the lower back round as the set gets hard.
  • Yanking the weight with torso rotation, which hides the imbalance this exercise exists to fix.
