How to do dumbbell one arm row(with support)
Master the setup, range of motion, and tempo for safer, more effective reps.
Overview
The Dumbbell One Arm Row is one of the most effective ways to train your lats, traps, and rhomboids. By using a bench for support, you take the strain off your lower back, allowing you to focus entirely on pulling heavy weight with your back muscles.
Because it's a unilateral (one-sided) move, it also forces your core to work hard to prevent your body from rotating. This makes it a great 'two-for-one' for back size and core stability.
Why Use It
- Builds serious thickness in the mid-back and lats.
- Allows for a greater range of motion and a deeper stretch than barbell rows.
- Reduces lower back fatigue by providing a point of support.
When to Use It
This is a 'meat and potatoes' back exercise. Use it as your primary or secondary pulling movement in any upper-body or back-focused session.
Instructions for Proper Form
Setup
- The Base: Place your left knee and left hand on a bench. Your right foot should be on the floor.
- The Grip: Pick up the dumbbell with your right hand. Let it hang straight down.
- The Spine: Flatten your back. Imagine you could set a glass of water on your back without it spilling.
Execution
- The Pull: Drive your right elbow up and back toward your hip. Don't just pull with your hand—think about your elbow.
- The Squeeze: At the top, pinch your shoulder blade toward the center of your back.
- The Stretch: Lower the dumbbell slowly until your arm is straight. Let the weight pull your shoulder blade slightly forward to feel the stretch.
Pro-Tip
Don't pull the dumbbell to your chest. Pull it toward your pocket! This engages the lats much more effectively and keeps your shoulder in a safer position.
Common Mistakes
- Torso Twisting: If you have to rotate your chest toward the ceiling to finish the rep, the weight is too heavy.
- The Bicep Pull: Pulling the weight to your shoulder instead of your hip uses too much arm and not enough back.
- Rounding the Back: This puts your spine at risk. Keep your chest up and your back flat.
Mistakes by Level
Beginner
- Rounding the upper back.
- Pulling the weight straight up to the armpit.
Intermediate
- Using momentum or 'shrugging' the weight up.
- Not getting a full stretch at the bottom.
Advanced
- Letting the hips shift and sway during heavy sets.
- Shortening the range of motion to use heavier weights.

Setup Requirements
- Place one knee and one hand on a flat bench for support.
- Your other foot should be planted firmly on the floor, slightly out to the side for balance.
- Keep your back flat and parallel to the floor.
- Let the dumbbell hang at arm's length, feeling a slight stretch in your shoulder blade.
Form Checklist
- Is my back flat, or am I rounding my spine?
- Am I pulling with my hand, or am I driving with my elbow?
- Is my torso staying still, or am I twisting to get the weight up?
- Am I feeling the stretch in my lat at the bottom?
Range of Motion
Pull the dumbbell up toward your waist/hip until your elbow is just past your torso, then lower it back down to a full stretch.
Breathing Pattern
Exhale as you pull the weight up; inhale as you lower it back down with control.
Tempo Guidance
1 second to pull, a brief pause at the top to squeeze the back, and 2 seconds to lower it down.
Caution Notes
- Avoid 'yanking' the weight off the floor. Start the move by pulling your shoulder blade back first.
Programming
Treat these guidelines as practical programming defaults, then scale load, volume, and frequency to match the rest of the training week.
Best For
- Building back thickness and strength.
- Improving posture by strengthening the muscles between the shoulder blades.
- Developing grip strength.
Goal Tags
Rep Ranges
- 6-10 reps for pure strength and thickness.
- 10-15 reps for muscle growth and endurance.
- 8-12 reps is the 'sweet spot' for most lifters.
Set Guidance
3-4 sets per arm.
Rest Guidance
60-90 seconds between arms. You may need more rest if you are going very heavy.
Frequency
Can be done 2-3 times per week.
Pairings
- Pair with a Chest Press for a balanced upper-body workout.
- Pair with a Plank to double down on core stability.
Audience Notes
- Beginners should focus on the 'elbow-to-hip' path to avoid using too much bicep.
- Advanced lifters can use 'dead-stop' reps (letting the weight rest on the floor between reps) to build explosive power.
Substitution Targets
- Seated Cable Rows if you want more constant tension.
- Chest-Supported Rows if your lower back is feeling sensitive.
Variations
Use progressions to increase difficulty when you master the movement, and regressions if you struggle with proper form or face mobility limitations.
Regressions
Bird-Dog Row
Forces a much lighter weight and extreme core focus.
Best for: Those needing core stability work.
Progressions
Kroc Row
High-rep, heavy-weight rows with a bit of 'controlled' momentum.
Best for: Advanced lifters building grip and upper back mass.
FAQ
Common Questions
Should I use straps?
If your grip is failing before your back does, straps are a great tool. However, try to do your warm-up sets without them to build grip strength.
Which foot should be forward?
Usually, the foot on the floor is slightly behind the knee on the bench to create a stable 'tripod' base.
