One-arm Dumbbell Row: Techniques, Benefits, and Mistakes to Avoid

The single or one-arm dumbbell row is a versatile exercise that targets multiple muscle groups, primarily in the upper body. It's particularly effective for strengthening the upper and central back, as well as the shoulders. This exercise also engages the forearm flexors, albeit to a lesser extent than other workouts.

Most commonly used in bodybuilding, the one-arm dumbbell row can also be beneficial for sports that require strength or hypertrophy development, such as powerlifting. Moreover, it can be a valuable tool in health-related contexts like injury prevention, rehabilitation, and functional reconditioning.

Despite its many benefits, this exercise also has its disadvantages when compared to other rowing exercises, such as the standing barbell row.

The Single Dumbbell Row: A Step-by-Step Guide

To execute the single dumbbell row effectively, follow these steps:

1. Positioning: Place a dumbbell of appropriate weight next to a flat bench. Stand next to the bench with your legs apart. The side of your body that will perform the exercise should be next to the dumbbell.
2. Stabilize: Place your non-working arm perpendicularly on the bench. Simultaneously, bend the knee on the same side to a 90° angle and rest it on the bench. Your body should be leaning forward, with the non-working side firmly resting on the bench.
3. Prepare: Extend the opposite leg slightly to the side and towards the back. This position allows the working arm enough space to perform the exercise.
4. Grip: Reach out and grip the dumbbell with your forearm in a neutral position, then lift it off the floor.
5. Execute: Inhale and begin the rowing motion. Keep your focus on the movement of the upper arm, not the forearm. Avoid twisting your torso, which is a common mistake when dealing with heavy weights.
6. Breathing: Exhalation can occur progressively, or be postponed towards the end of the repetition. We recommend the latter as it helps maintain core stability, especially with heavy loads.

Advantages of the Single Dumbbell Row

The single dumbbell row offers several key benefits. For one, it allows for almost isolated engagement of the back muscles, reducing the involvement of the forearm flexors. Furthermore, when performed with one knee on a bench, it provides an excellent solution for those experiencing lower back pain or issues. This position reduces the strain on the spine and associated muscles by distributing the weight onto the arm and knee.

Disadvantages of the Single Dumbbell Row

Despite its advantages, the single dumbbell row does have some drawbacks. Compared to standing rows, this exercise involves less overall effort. The limited engagement of the deep back muscles, the quadratus lumborum, and the gluteus muscles makes it less functional and less preparatory for weightlifting exercises.

Common Mistakes to Avoid

To ensure safe and effective execution of the single dumbbell row, avoid these common errors:

• Poor positioning on the bench, with the knee or arm placed too far forward or backward.
• The non-working leg positioned too close to the bench or dumbbell.
• Loss of focus on the shoulder blades.
• Improper synchronization of breathing.
• Excessive twisting or oscillation of the torso.
• Incomplete range of motion during the rowing movement.

In conclusion, the single dumbbell row is a versatile and effective exercise for upper body strength and conditioning. As with any exercise, it's crucial to use proper form and avoid common mistakes to ensure safety and effectiveness.
