In a row, the major muscle group being used is the back, but the biceps help to pull the weight up from the elbow. Here's how to do a single-arm row:
- Start standing with your feet hip width apart, and a dumbbell in your right hand.
- Step your left leg in front of your and hinge your hips forward about 45 degrees.
- Bend your elbow and bring the dumbbell up to your hip.
- Straighten your elbow to return to the starting position.
- Repeat for 10 reps on the right arm, then complete 10 reps on the left arm.
