One Arm Dumbbell Row does not need to look dramatic to be effective. Clean positions and a steady tempo matter more than chasing load or speed. The exercise mainly trains lats and mid back, while rhomboids, rear delts, and biceps help support and control the movement. You will use a flat bench and a single dumbbell while working from standing in a stable stance.
What makes a good One Arm Dumbbell Row repetition?
Let the shoulder blades and elbows follow the intended path without turning the rep into a shrug or lower-back swing. The movement is approachable once the setup is familiar, but balance, load control, or multi-joint coordination make clean repetitions more demanding.
Muscles worked
Primary
Lats and Mid back
These muscles should carry most of the intended work when the setup and movement path stay consistent.
Supporting
Rhomboids, Rear delts, and Biceps
These muscles assist the movement or help keep the rest of your position steady.
Set up before you move
Start from standing in a stable stance. Set your hands and feet so the position feels balanced before the first repetition. Check that a flat bench and a single dumbbell are secure and adjusted before you begin.

Common mistakes to avoid
Starting before the setup is stable
Do not rush the first position. Set the left support hand and knee on the bench, keep the back flat, and hold the dumbbell in the right hand. Make that setup feel repeatable before adding speed or resistance.
Letting the working position drift
Keep your starting alignment consistent through the rep. If another part of the body has to swing or twist, reduce the load or range.
Rushing the return
The return is part of the exercise, not a pause between efforts. Lower the left dumbbell to the long-arm finish.
Forcing a range you cannot control
Both sides shown sequentially; support hand and same-side knee stay on bench.
Sets, reps, and rest
A practical starting point is 3–4 sets of 6–10 controlled repetitions. Rest 90–180 seconds between challenging sets. Choose a load that leaves one or two technically clean repetitions in reserve while you learn the movement.
Treat this as a starting framework. Your load and volume should match your current technique, recovery, and training plan.
