One-Arm Dumbbell Row
Quick answer
The One-Arm Dumbbell Row mainly works the lats, with help from the traps and biceps. Single-arm pull braced on a bench that targets the lats and corrects imbalances. Beginners: 2–3 sets of 10–12 reps with a load you control.

How to do it
- Place one knee and the same-side hand on the bench, the other foot on the floor, back flat.
- Grip the dumbbell with your free hand, arm extended under your shoulder.
- Pull the dumbbell toward your hip, keeping your elbow close to your body.
- Lower slowly until you feel a stretch in your back, then switch sides at the end of the set.
