What Is Single-Arm Dumbbell Row Exercise?

The Single-Arm Dumbbell Row is a strength-training exercise focusing on the upper back muscles, particularly the latissimus dorsi. To perform this exercise, start by placing one knee and hand on a bench, with the opposite foot on the ground. Hold a dumbbell in the free hand, allowing it to hang directly beneath the shoulder.

Initiate the movement by pulling the dumbbell towards the hip in a rowing motion, keeping the elbow close to the body and squeezing the shoulder blade. Lower the dumbbell in a controlled manner and repeat the movement for the desired number of repetitions. This exercise is effective for improving back strength, promoting balanced muscle development, and enhancing posture by targeting the muscles responsible for scapular retraction.

What Muscle Groups Are Targeted?

The Single-Arm Dumbbell Row primarily targets the muscles of the upper back and arms. The key muscle groups worked during this exercise include:

1. Latissimus Dorsi:
   • The lats are the largest muscles in the upper back and play a central role in the rowing movement, especially when pulling the dumbbell towards the hip.
2. Rhomboids:
   • Located between the shoulder blades, the rhomboids are engaged during the rowing motion, contributing to scapular retraction.
3. Trapezius (Middle and Lower Fibers):
   • The middle and lower fibers of the trapezius assist in the retraction of the shoulder blades and support the movement.
4. Erector Spinae:
   • The muscles along the spine, known as the erector spinae, are engaged to stabilize the back during the rowing motion.
5. Rear Deltoids:
   • The rear deltoids, located at the back of the shoulders, are activated as the arm is pulled back.
6. Biceps Brachii:
   • The biceps play a secondary role in the exercise, assisting in elbow flexion as the dumbbell is lifted.
7. Teres Major:
   • The teres major, located on the outer edge of the scapula, is involved in the rowing movement.
8. Forearm Muscles:
   • Grip strength is required to hold the dumbbell, engaging the forearm muscles.

By targeting these muscle groups, the Single-Arm Dumbbell Row is effective for building upper back strength, improving posture, and promoting balanced muscle development in the upper body.
