One-Arm Dumbbell Row
The one-arm dumbbell row plants one hand and one knee on a bench while the other arm pulls a dumbbell up toward your hip, isolating one side of your back at a time. It builds the middle back and lats without asking your lower back to stabilize a bar, which makes it a solid pulling movement for people who are newer to lifting.
Why it works
Kneeling on the bench fixes your hips and spine in place, so the muscles doing the actual pulling, mainly the middle back and lats, don't have to compete with anything else for the effort. Each side works independently, which tends to expose and correct any strength gap between your left and right back rather than letting a stronger side compensate for a weaker one, the way it can on a barbell row.
Set up
- Place your left knee and left hand on a flat bench, keeping your back roughly parallel to the floor.
- Plant your right foot on the floor, a little wider than the bench for balance.
- Hold a dumbbell in your right hand, arm hanging straight down from the shoulder.
- Keep your spine neutral, not rounded or arched, before the first pull.
How to do it
- Pull the dumbbell straight up toward your hip, leading with your elbow.
- Keep your elbow close to your body as it travels, rather than flaring out to the side.
- Squeeze your shoulder blade toward your spine at the top of the pull.
- Pause for a beat, then lower the dumbbell back down under control.
- Let your shoulder stretch forward slightly at the bottom without rounding your back.
- Finish all reps on one side before switching hands and knees.
Form cues
- Elbow leads, not the hand.
- Keep the elbow close to your ribs.
- Flat back, no twisting the torso.
- Pull to the hip, not the armpit.
Breathing: Exhale as you pull the dumbbell up, inhale as you lower it back down.
Common mistakes
Rotating the torso to help swing the dumbbell up.
Fix: Keep both shoulders square to the floor and let your back muscles do the pulling instead of the twist.
Rounding the lower back over the course of the set.
Fix: Reset your spine to neutral between reps if you feel it curling, and drop the weight if it keeps happening.
Stopping the pull halfway instead of reaching the hip.
Fix: Aim the dumbbell toward your hip bone, not your armpit, so your back gets the full range.
Dropping the dumbbell fast on the way down.
Fix: Lower it over two or three seconds; the descent trains your back just as much as the pull.
How to program it
- Three sets of 8 to 12 reps per arm works well as your main back pull for the day.
- Because each side only works independently and the load is a single dumbbell, most people can row twice a week without it eating into recovery.
- Pair it with a horizontal push like a dumbbell bench press to balance out a session.
- Move up in weight once you can finish every rep without your torso twisting to help.
Safety notes
- Stop the set if your lower back starts to ache rather than pushing through more reps.
- Keep the resting arm's elbow soft on the bench instead of locking it straight.

Frequently asked questions
How many sets and reps of the one-arm dumbbell row should I do?
Three sets of 8 to 12 reps per arm is a solid starting point for building back strength and size.
Can I do a one-arm dumbbell row without a bench?
Yes. Brace your free hand on a sturdy chair, a low wall, or even your own bent knee, as long as your spine stays flat and supported.
One-arm dumbbell row vs bent-over barbell row, which is better?
The one-arm version isolates each side and needs less lower-back stabilizing, which suits beginners. The barbell row loads both sides at once and lets you handle more total weight once your form is solid.
Why does my lower back hurt during dumbbell rows?
It's usually a rounded or twisted spine taking the load instead of your back muscles. Keep your knee and hand planted, your back flat, and drop the weight if the ache continues.
