Dumbbell Row
The dumbbell row has you supporting yourself with one hand and one knee on a bench, torso close to parallel with the floor, pulling a dumbbell up toward your hip with the free arm. It builds the lats and middle back through a full pulling range, with the biceps helping finish the motion, and the bench support lets you focus entirely on the pull without your lower back working to hold you up. It suits anyone building back strength and width, especially if a bent-over barbell row has felt hard on the lower back.
Why it works
Pulling the dumbbell from a fully extended arm up to your hip drives your shoulder blade through a full range of retraction, which is what recruits the lats and middle back through their whole working length rather than just a partial one. Because your hand and knee are braced on the bench, your spine doesn't have to fight to hold a bent-over position the way it does in a standing row, so nearly all the effort goes into the pull itself instead of into staying upright. Training one arm at a time also lets you focus fully on driving the elbow back and squeezing at the top, without the other arm's fatigue or momentum sneaking in to help.
Set up
- Place one knee and the same-side hand on a flat bench, keeping your back flat and roughly parallel to the floor.
- Hold a dumbbell in your free hand, arm hanging straight down.
- Plant your other foot firmly on the floor for balance.
How to do it
- Pull the dumbbell straight up toward your hip, leading with your elbow.
- Keep the dumbbell close to your body as it travels, brushing past your ribs.
- Squeeze your shoulder blade back at the top of the pull.
- Lower the dumbbell under control until your arm is fully extended again.
- Complete all reps on one side before switching to the other arm.
Form cues
- Elbow leads the pull, close to the body.
- Squeeze the shoulder blade at the top.
- Back stays flat, roughly parallel to the floor.
- Full arm extension at the bottom of every rep.
Breathing: Exhale as you pull the dumbbell up, inhale as you lower it back down.
Common mistakes
Rotating the torso to help heave the dumbbell up instead of pulling with the back.
Fix: Keep your hips and shoulders square to the bench throughout the set; if you need to rotate to finish a rep, the weight is too heavy.
Stopping the pull short and never fully extending the arm at the bottom.
Fix: Let the dumbbell travel all the way down until your arm is straight before starting the next pull, so the lats get a full stretch each rep.
Shrugging the shoulder up toward the ear instead of pulling the elbow back.
Fix: Focus the motion on driving the elbow behind you and squeezing the shoulder blade, keeping the shoulder itself down and relaxed.
Letting the supporting arm bend and collapse, dropping the chest toward the bench.
Fix: Keep the supporting arm locked and your back flat throughout; if it starts to collapse, the weight is likely too heavy for now.
How to program it
- Eight to ten reps per side, for two or three sets, is a strong working range for building both back strength and size.
- This is a genuinely loaded compound pull, so once a week as your main back-building movement is enough; add a second session only if it's the only direct back work that week.
- Do the weaker or less coordinated side first each session so it gets your freshest effort.
- Pairs naturally with a pressing exercise like a bench press or overhead press on the same day, since they work opposing muscle groups.
Safety notes
- Keep your back flat and avoid rounding it to reach further down for the dumbbell; adjust your bench height or grip point instead of rounding your spine.
- Choose a weight you can pull with a controlled elbow-first motion; jerking the dumbbell up with your torso is where most rowing strain happens.

Frequently asked questions
How many sets and reps of dumbbell rows should I do?
Two or three sets of 8 to 10 reps per side is a solid range for building strength and size. Since it's a loaded compound pull, once a week is enough as your main back movement.
Why does my lower back hurt during dumbbell rows?
It's usually from rounding the spine to reach the dumbbell or twisting the torso to muscle the weight up. Keep your back flat, lower the weight if needed, and make sure your supporting arm stays locked to hold the bench position steady.
Dumbbell row vs barbell row, which is better?
The dumbbell row lets you train one side at a time with bench support, which is easier on the lower back and helps fix side-to-side imbalances. The barbell row can move more total weight but demands more from your lower back to hold the bent-over position.
Can I do a dumbbell row without a bench?
Yes, a bent-over two-dumbbell row without any support trains the same pulling motion, though it asks more from your core and lower back to hold the position.
