One-Arm Dumbbell Row
Also works: Biceps · Lats · Shoulders
One knee and one hand on a bench, the other hand rowing a dumbbell from a full stretch to the ribs. Bracing three points against the bench takes the lower back out of the equation, so you can row heavy on a day your spine has already had a deadlift, and each side gets its own honest rep count.
Own the movement
Set up first, then execute. Every cue below is something you can check on your next set.
Before the first rep
- Put your right knee and right hand on the bench, left foot flat on the floor a little behind your hip.
- Set your torso roughly parallel to the floor and your back flat — a slight natural arch, not a rounded curve.
- Let the dumbbell hang with your arm straight and your shoulder blade allowed to slide forward toward the floor.
- Square your hips to the bench before the first rep so you are not already rotated.
- Keep your neck in line with your spine; eyes on the bench a foot ahead of your hand, not up at the mirror.
Every rep
Breathing & tempo — Exhale as you row, inhale on the way down. One second up, one second paused at the top, three seconds down.
Sets, reps & load
Where to start, and what to change when it stops being hard.
Most trained men start around 20-25 kg and most trained women around 8-12 kg. A useful benchmark is rowing half your bodyweight in one hand for 10 controlled reps. Add weight once you can pause the top of every rep for a full second with a level torso — if you cannot pause it, the extra kilos are being lifted by your hips.
What goes wrong
The errors that show up most often, and the cue that fixes each one.
Keep your shoulders level with the floor and pick a dumbbell 20% lighter until you can hold that for all twelve reps. Film one set from behind — the rotation is invisible from inside the movement.
Pause for a full second at the top of each rep with the shoulder blade squeezed back. A weight you cannot pause you cannot row.
Let the arm straighten completely and the shoulder blade travel forward at the bottom of every rep. Touching the dumbbell lightly to the floor between reps forces the full range.
Row the weaker side first, count its reps, and stop the strong side on that same number. Give the weak side one extra set at the end of the exercise.
Why bother
A bent-over barbell row is limited by how long your spinal erectors can hold a hinge. Put a knee and a hand on the bench and that limit disappears — the bench holds you up, so the set ends when your back muscles are done rather than when your lower back gives out.
Rowing one side at a time also exposes what a barbell hides. Most people find one side rows two or three reps further than the other, and the dumbbell gives that side nowhere to hide. Always start the set with your weaker arm and match the stronger arm to its rep count.
Where it fits
Second or third on a pull day, after your vertical pulling, for three to four sets of 8-12 per side. It pairs particularly well with a heavy deadlift day precisely because it adds back volume without adding spinal loading. Twice a week is comfortable for most people.

Asked and answered
Should I row to my hip or to my chest?
To the side of your ribcage, roughly level with the bottom of your sternum. Rowing high toward the shoulder shifts the work to the rear delts and traps; rowing low toward the hip turns it into a straight-arm pull with a bent elbow. Ribs is the compromise that keeps the lats and mid-back doing the job.
Do I need a bench, or can I brace on a rack?
Any stable waist-height support works — a rack upright, a heavy dumbbell rack, an incline bench set high. The bench-and-knee version is just the most stable. What matters is that one hand takes your torso's weight so your lower back is not the limiting factor.
Is it cheating to use a little body English on the last reps?
Yes, and it is worth being honest about it. A small controlled heave on the final rep or two of a set is a legitimate intensity technique if the eccentric stays slow. Doing it from rep one means you picked a dumbbell you cannot row, and the mid-back never gets the tension it was there for.
How does this compare to a barbell row?
It builds the same muscles with less systemic and spinal cost, a longer range of motion, and honest per-side feedback. The barbell row moves more total load and trains the isometric hinge, which the dumbbell version deliberately removes. Run both: barbell on your heavy day, dumbbell for volume.
