How To Do Single Arm Dumbbell Rows: Step-by-Step Guide for Proper Form and Maximum Back Gains
Among the most effective movements for building a strong, balanced upper body, the single arm dumbbell row stands out as a staple in both beginner and advanced workout routines. This unilateral exercise targets a range of crucial back muscles, enhances posture, and helps correct strength imbalances all with just one dumbbell and a bit of space.
For fitness enthusiasts in the UK who value efficient training without relying heavily on machines, this exercise delivers high returns. This article offers a detailed breakdown of how to perform single arm dumbbell rows with proper form, along with tips to avoid injury and optimise performance.
What Are Single Arm Dumbbell Rows?
The single arm dumbbell row is a unilateral resistance training exercise designed to strengthen the upper and middle back, as well as the biceps and shoulders. It involves pulling a dumbbell towards your body while supporting yourself on a bench or similar surface.
Primary Muscles Targeted
| Muscle Group | Specific Muscles Involved |
|---|---|
| Upper Back | Latissimus dorsi, rhomboids, trapezius |
| Shoulders | Posterior deltoids |
| Arms | Biceps brachii |
| Core (Stabilising) | Obliques, erector spinae, transverse abdominis |
This movement is key for postural support, muscle symmetry, and scapular stability, all of which are essential for injury prevention and functional strength.

Step-by-Step Instructions to Perform Single Arm Dumbbell Rows
1. Setup
- Choose an appropriate dumbbell: Start light if you’re new to resistance training, typically between 6–12 kg for beginners.
- Positioning:
- Place one knee and the same-side hand on a flat bench or sturdy surface.
- Your supporting arm should be directly under the shoulder, knee under the hip.
- The other foot should remain firmly planted on the ground for balance.
- Body alignment: Maintain a neutral spine from neck to hips. Engage your core to avoid arching or twisting.
2. Execution
- Grip the dumbbell with the free hand, palm facing inward.
- Pull the dumbbell towards your hip, keeping your elbow close to your body.
- At the top of the movement, squeeze your shoulder blade towards your spine.
- Lower the dumbbell in a slow, controlled manner, keeping tension in your back.
3. Breathing
- Exhale as you pull the dumbbell up.
- Inhale as you return to the starting position.
Common Form Mistakes to Avoid
Avoiding these mistakes is crucial for targeting the correct muscles and preventing injury:
| Mistake | Why It’s a Problem | How to Correct |
|---|---|---|
| Rounding or twisting the spine | Leads to lower back strain | Keep your core tight, spine neutral |
| Using momentum | Reduces effectiveness and increases risk | Slow down and control each rep |
| Letting the shoulder drop/shrug | Shifts focus away from back muscles | Focus on scapular retraction |
| Not completing full range | Limits gains and mobility | Ensure full extension and contraction |
Variations and Modifications
Depending on your skill level and available equipment, try these popular variations:
- Supported Row on Bench: Standard version, ideal for beginners and intermediate users.
- Standing Bent-Over Row: Challenges balance and engages the core.
- Renegade Row: Performed in a plank position; boosts core strength and coordination.
- Slow Tempo Rows: Increases time under tension for hypertrophy.
How to Incorporate Single Arm Dumbbell Rows into Your Workout
For optimal results, include this movement in your upper-body or full-body routines 2–3 times per week.
| Fitness Level | Sets | Reps | Rest Between Sets |
|---|---|---|---|
| Beginner | 3 | 10–12 | 60–90 seconds |
| Intermediate | 3–4 | 8–10 | 60 seconds |
| Advanced | 4 | 6–8 | 45–60 seconds |
Pairing Recommendations:
- Push-ups or dumbbell chest presses for push-pull balance
- Deadlifts or good mornings for posterior chain synergy
- Pull-ups or lat pulldowns to target the upper back in varied angles
Prioritise a dynamic warm-up before training, including arm swings, band pull-aparts, and thoracic mobility drills.
Benefits of Single Arm Dumbbell Rows
- Unilateral Strength: Identifies and corrects muscular imbalances.
- Posture Improvement: Strengthens upper back and counters desk-related slouching.
- Scapular Control: Enhances shoulder joint stability and mobility.
- Grip and Arm Endurance: Boosts performance in pulling and lifting tasks.
- Functional Strength: Supports athletic movements and everyday tasks like lifting bags or children.
Safety Tips and Precautions
- Always warm up before lifting to prepare muscles and joints.
- Progress gradually by increasing weight only when form is solid.
- Don’t push through sharp pain it’s a signal, not a challenge.
- If unsure about your form, consult a qualified personal trainer or a REPs-registered fitness professional in the UK.
