One-Arm Dumbbell Row
The best back-builder for learning to actually feel your lats work.
Setup
- One knee and same-side hand on the bench; other foot planted wide.
- Back flat like a table, dumbbell hanging straight down.
How To Do It
- Row the dumbbell toward your hip pocket — not your armpit.
- Lead with the elbow; keep the shoulder away from your ear.
- Squeeze the shoulder blade at the top for one second.
- Lower long and controlled — get the stretch.
Breathing
Exhale as you row, inhale as you lower.
Common Mistakes
- Twisting the torso to heave the weight — the table doesn't tilt.
- Rowing to the chest — hip pocket puts it in the lats.
- Shrugging — pull the shoulder DOWN and back.
Programming It
Three to four sets of 8-12 per side.
Why This Exercise Works
Supporting one hand on a bench takes the lower back out, so the lat can be loaded heavily without the hinge fatiguing first. It also allows a longer range than a barbell — the dumbbell can travel past the ribs where a bar hits the chest.
Where You Should Feel It
Lats and mid-back through a longer range than a barbell allows, because the dumbbell can travel past the ribs. The supported hand takes the lower back out entirely.
Where It Fits in a Program
The best back-builder for learning to actually feel your lats work. This is main-lift work. Put it first, when your technique is still honest.
Progressing and Regressing It
To progress the one-arm dumbbell row: add the next pair up, or pause at the top. To regress it: reduce the load until the torso stops rotating to finish.
Who It's For
Anyone whose barbell row is limited by their lower back, and anyone with a side-to-side difference. One of the most useful back exercises there is.
Equipment and Substitutions
This version uses a dumbbell and a bench. No dumbbells? A kettlebell of similar weight works for almost all of this, and the cable and machine versions below cover the rest.

Do I need a dumbbell and a bench to do this?
This version uses a dumbbell and a bench, and it trains the back, lats, biceps. Any hand-held load will do — kettlebell, plate, or a filled bag. The related list below covers the machine versions.
Is this safe if I have an existing injury?
The one-arm dumbbell row puts the shoulder and elbow under load through a range many people have lost, so a cranky shoulder usually objects here before anything else does. Pain that pinches at a specific point is worth assessing; ordinary training discomfort is not. Not medical advice.
