Step-by-Step Instructions

1. 1

   Place one knee and the same-side hand on a flat bench for support, with the other foot planted firmly on the floor slightly behind the hip.

2. 2

   Hold a dumbbell in the free hand with the arm fully extended, allowing the lat to stretch at the bottom.

3. 3

   Maintain a flat back parallel to the floor, with the core braced to resist rotation toward the loaded side.

4. 4

   Initiate the row by retracting the shoulder blade, then drive the elbow upward and back toward the hip, pulling the dumbbell to the lower ribcage.

5. 5

   Squeeze the lat and mid-back at the top for 1-2 seconds, keeping the shoulder packed down away from the ear.

6. 6

   Lower the dumbbell under control over 2-3 seconds to full arm extension, allowing a slight protraction at the bottom to maximize lat stretch before the next rep.

Common Mistakes

• Rotating the torso to heave the dumbbell up rather than pulling with the lat, which converts the exercise into a rotational cheat row.

• Pulling the dumbbell toward the armpit or chest instead of the hip, which over-recruits the upper traps and rear delts at the expense of the lats.

• Rounding the lower back due to poor hip-hinge mechanics or a bench that is set too low.

• Shrugging the shoulder up toward the ear at the top instead of keeping the scapula depressed for proper lat engagement.

About This Exercise

The unilateral dumbbell row is a fundamental horizontal pulling exercise that targets the latissimus dorsi, middle trapezius, rhomboids, and rear deltoids while the biceps brachii serves as a secondary mover. The single-arm setup allows a greater range of motion than bilateral rows, enables heavier relative loading per side, and creates an anti-rotation demand on the core that strengthens the obliques and quadratus lumborum. This exercise is a cornerstone of balanced back development and posture correction.
