Dumbbell One Arm Bent-over Row
Learn how to do the Dumbbell One Arm Bent-over Row with proper form and technique. This dumbbell exercise primarily targets your Upper Back, with secondary emphasis on Biceps, Forearms.
How to Do the Dumbbell One Arm Bent-over Row
Follow these steps to perform the Dumbbell One Arm Bent-over Row with correct form:
- 1Stand with your feet shoulder-width apart, holding a dumbbell in one hand with your palm facing your body.
- 2Bend your knees slightly and hinge forward at the hips, keeping your back straight and your core engaged.
- 3Let the dumbbell hang straight down towards the floor, with your arm fully extended.
- 4Pull the dumbbell up towards your chest, keeping your elbow close to your body and squeezing your shoulder blades together.
- 5Pause for a moment at the top, then slowly lower the dumbbell back down to the starting position.

Muscles & Anatomy
The single-arm dumbbell row is one of the most effective exercises for developing the latissimus dorsi, middle trapezius, and rhomboids because it allows a full range of motion — including shoulder girdle retraction at the top — that bilateral rowing movements often lack. With the opposite hand braced on the bench, the torso is horizontal and the working arm pulls the dumbbell from a dead-hang stretch (maximum lat lengthening) to a fully retracted position (maximum lat shortening). The rear deltoid and biceps brachii are heavily involved as synergists. Because each side works independently, the single-arm row naturally corrects left-right strength imbalances.
Pro Tips for Better Results
- 1Pull the elbow — not the hand. Think of your arm as a hook and focus on driving your elbow toward your hip pocket. This cue shifts focus to the lats and away from the biceps.
- 2At the top of the rep, fully retract the scapula — squeeze the shoulder blade toward the spine as hard as you can and hold for a second. This peak contraction is where the rhomboids and middle traps do their best work.
- 3Use a full range of motion: let the dumbbell fully lower until your shoulder drops forward and the lat is completely stretched at the bottom. Cutting the range of motion short is the most common reason people don't develop their lats.
Common Mistakes to Avoid
✗ Using too much bicep and not enough lat
Fix: Initiate every rep with a shoulder blade retraction — pull the shoulder blade down and back before bending the elbow. This pre-activates the lat and ensures it leads the movement.
✗ Twisting the torso on each rep (rowing the weight with body momentum)
Fix: Keep the torso locked in a horizontal position. Rotation uses momentum to help the weight up — reduce the weight and maintain a strict, stationary trunk.
✗ Not bracing the supporting arm properly
Fix: The hand on the bench should be directly below the shoulder (not forward). Push actively into the bench to create a stable base — this transfers directly to heavier rowing loads.
✗ Stopping the range of motion short at the bottom
Fix: Allow the shoulder to drop forward and the arm to fully extend at the bottom. The lat is most lengthened in this position. Cutting it short eliminates the stretched-position stimulus.

Variations & Alternatives
Barbell Bent-Over Row
Both hands on the bar, hinging at the hips. The bilateral version allows heavier loading and stresses the spinal erectors as stabilizers. Less range of motion than the single-arm version but better for developing maximal pulling strength.
Cable Single-Arm Row
Same mechanics as the dumbbell version but with constant cable tension throughout the range of motion, including the full stretch at the bottom. The cable prevents the weight from going 'slack' like a dumbbell does, increasing time under tension.
Chest-Supported Dumbbell Row
Lie face-down on an inclined bench and row both dumbbells simultaneously. Removes all possibility of body English or torso rotation — the support makes this the strictest row variation and is excellent for isolating the middle back.
