Barbell One Arm Bent Over Row
The one-arm barbell row in a bent-over position strengthens the upper back and improves scapular control, helping to correct imbalances in the back. The movement specifically targets the muscles of the scapula and mid-back, while the core, glutes, and hamstrings stabilize the position. Keep the technique tight: neutral back and minimal torso rotation.

Why Barbell One Arm Bent Over Row?
The one-arm barbell row in a bent-over position is an excellent exercise for developing upper back strength and muscle balance. This movement specifically targets the muscles of the scapula and mid-back, such as the latissimus dorsi, trapezius, and posterior deltoids. Its unique advantage is the unilateral load, which forces the core to work harder to stabilize the position and helps correct body side imbalances. If you notice that one side is stronger or controls movements better, this row is a perfect tool for restoring balance. This exercise is great for intermediate fitness enthusiasts who want to take their back training to the next level and develop functional strength. It is effective because it simulates many movements in daily life and sports where one side of the body works independently. Additionally, it improves scapular control, which is critical for shoulder health and versatile upper body strength production. A strong and balanced upper back not only looks good but also prevents posture problems and back pain. Remember to keep your back neutral and avoid excessive torso rotation to maximize the effectiveness of the movement and minimize the risk of injury. Using a bench for support helps maintain a stable position and focus on the target muscles.

How to perform
Setup
- Choose an appropriate load and place the barbell on the floor. Stand with your feet hip-width apart next to the center of the bar.
- Grip the bar with one hand in an overhand grip at the knurling in the center (or slightly outside of it). Support your free hand on your thigh or a bench.
- Push your hips back, lean forward 30–45°, keep your spine neutral, knees soft, and neck long. Engage your core and pull your shoulder blade slightly back down before the first pull.
Execution
- Inhale. Pull your elbow back towards your hip, keeping your forearm close to your side and wrist neutral.
- Squeeze your shoulder blade towards your spine at the top position and pause for 1 second without rotating your torso.
- Lower the barbell in a controlled manner until your arm is nearly straight, maintaining scapular support and body tension throughout. Exhale during the pull, inhale during the lowering (or vice versa consistently). Repeat the desired number of repetitions, switch sides, and use the same load and tempo.
Coaching cues
- •Pull with your elbow, not your hand – feel the shoulder blade sliding back down.
- •Keep your hips and chest straight; avoid rotation and jerking at the beginning or end of the movement. Press your feet into the floor and keep your weight centered over your feet.
- •Neck long, gaze at the floor a few meters ahead.
- •Grip the handle tightly but do not bend your wrist; if your grip fails, use chalk or a thicker grip.
- •A short 0.5–1 second pause at the top position enhances scapular activation.
Common mistakes
❌ Excessive torso rotation
Why it's wrong: Excessive torso rotation reduces the load on the upper back muscles and shifts pressure to the lower back, which can lead to injuries.
✓ Fix: Focus on keeping the pelvic line as stable as possible and allow the movement to occur primarily in the shoulder blade and arm area. Tight core support is key.
❌ Too much weight
Why it's wrong: Using too heavy a weight can easily compromise technique, making the movement jerky and preventing the target muscles from receiving optimal stimulation. Additionally, the risk of injury increases.
✓ Fix: Reduce the weight and focus on a controlled, steady range of motion. The goal is to feel the target muscles working, not just to lift the weight.
❌ Rounded back
Why it's wrong: Rounding the back during the position or pull places undue stress on the spine and significantly increases the risk of disc injuries.
✓ Fix: Keep your back in a neutral position throughout the movement. Imagine your back is straight and stable like a tabletop. Engage your core and squeeze your shoulder blades together at the top of the pull.
Frequently asked questions
How often should I do the one-arm barbell row?
Generally, 1-3 times a week is a suitable frequency depending on your overall training volume and recovery ability. If you want to correct side imbalances, you can focus on the weaker side a bit more often or add sets for it. Listen to your body and ensure adequate recovery.
Can I do the movement without a bench?
Yes, you can also perform the movement without a bench by keeping your free hand stable on a support point such as a rack or your thigh. However, a bench provides better stability and allows for a deeper stretch, but you can still get a good workout for your core and upper back without one.
How do I choose the right weight for this movement?
Always start with a light weight and focus on technique. When you can perform the desired number of repetitions with clean technique and feel the activation of the target muscles, you can gradually increase the weight. Never sacrifice technique for weight, especially in this movement where back health is at stake.
Why do a one-arm row instead of a two-arm row?
The one-arm row effectively helps correct body side imbalances and develop unilateral strength. It forces the core to work harder to stabilize the body, improving body control and functional strength. Additionally, it may allow for a deeper stretch and contraction in the target muscles.
Safety tips
- Always start with a light weight and ensure the purity of your technique before adding weights.
- Keep your back in a neutral position throughout the movement to avoid lower back injuries.
- Focus on a controlled and steady range of motion; avoid jerky movements or swinging.
- Engage your core tightly to keep your body stable and prevent excessive rotation.
- Breathe correctly: exhale during the pull and inhale during the return.
