One-Arm Dumbbell Row Steps:
Step 1: With a dumbbell on each side of a flat bench, place your right hand and your right knee on the flat bench.
Step 2: With a straight back and your stomach parallel to the weight bench, grasp the left-hand side dumbbell with your left hand, palm facing towards you.
Step 3: Exhaling, bring the dumbbell straight up to your chest by bending the elbow back to a 90-degree angle.
Step 4: Inhaling, lower the dumbbell until your arm is straight down and your elbow has only a slight bend.
Step 5: Repeat for a full set of repetitions and then switch sides.
