Learn how to target your lats and mid-back without rounding your spine or relying on torso rotation during single-arm dumbbell rows.
The single-arm dumbbell row is an unrivaled tool for building unilateral back thickness, correcting lat strength asymmetries, and improving grip strength. Yet many lifters turn this movement into a jerky lawnmower rip that strains the lower back and shoulder joint.
Musculature Recruited
When performed correctly, the dumbbell row targets the latissimus dorsi, rhomboids, middle and lower trapezius, posterior deltoid, and brachialis. Because it is performed unilaterally, it also demands substantial isometric core stabilization from the obliques.
The Arc vs. The Up-and-Down Trap
The biggest error in dumbbell rowing is pulling the weight straight up into your armpit. When you pull straight up, the bicep does the lion's share of the work and the shoulder head tilts forward into anterior impingement.
Start with the dumbbell hanging slightly in front of your shoulder. Pull the weight in a gentle backward arc toward your hip crease, driving the movement with your elbow rather than your wrist. This maintains constant tension on the latissimus dorsi fibers.
Top Mistakes to Avoid
- Torso Twisting: Rotating your ribcage toward the ceiling to heave the weight up. Keep your shoulders square to the bench throughout.
- Cervical Hyperextension: Craning your neck up to look into a mirror. Keep your neck packed in a neutral line with your thoracic spine.
- Dropping the Weight Fast: Letting the dumbbell pull your shoulder out of joint at the bottom. Control the eccentric phase for 2 seconds.
