"One-Hand Dumbbell Row: Targeted Muscles & Benefits"

By Richard WhiteNovember 21, 2025

The one-arm dumbbell row is a versatile and effective exercise that targets multiple muscle groups, making it a staple in many fitness routines. This compound movement not only builds strength but also improves functional movements and posture. Let's delve into the muscles worked during this exercise and understand how to perform it correctly for optimal results.

Primary Muscles Worked

The one-arm dumbbell row primarily targets the back muscles, which are responsible for maintaining posture and supporting spinal health. The main muscles worked are:

Latissimus Dorsi (Lats): These are the largest muscles in the back, responsible for the 'V' shape in a well-developed physique. They extend from the middle back to the armpits and are the primary movers in this exercise.
Rhomboids: Located between the shoulder blades, these muscles help to retract and elevate the scapula (shoulder blade).
Trapezius (Traps): The traps extend from the base of the skull to the middle back and are responsible for moving the shoulders and neck. The middle and lower traps are engaged during this exercise.

Secondary Muscles Worked

While the one-arm dumbbell row is primarily a back exercise, it also engages several secondary muscle groups to maintain stability and facilitate movement.

❌ Common Dumbbell Row Mistakes and How to Avoid Them

Biceps Brachii: The biceps are engaged as secondary movers to help flex the elbow and stabilize the dumbbell.
Forearm Muscles: The flexor muscles in the forearms are engaged to grip the dumbbell and maintain a stable wrist position.
Core Muscles: The core is engaged to maintain stability and balance throughout the movement. This includes the rectus abdominis, obliques, and lower back muscles.

Proper Form and Technique

Proper form is crucial to effectively target the intended muscles and prevent injuries. Here's a step-by-step guide to performing the one-arm dumbbell row with correct technique:

Step	Action
1	Place a dumbbell on the floor and position yourself next to it, with your non-working hand and knee on a bench or stable surface. Your working arm should be extended towards the floor, holding the dumbbell.
2	Engage your core and maintain a neutral spine. This is your starting position.
3	Pull the dumbbell towards your torso, keeping your elbow close to your body and maintaining a neutral wrist position. Focus on squeezing your back muscles at the top of the movement.
4	Lower the dumbbell in a controlled motion, resisting the weight throughout the entire range of motion. Do not let the weight pull you down.

Repeat the desired number of repetitions, then switch arms to work the other side. Remember to maintain a controlled tempo and focus on the mind-muscle connection for optimal results.

Progressions and Variations

Once you've mastered the one-arm dumbbell row, you can progress to more challenging variations or incorporate additional exercises to further develop your back muscles. Some progressions and variations include:

Inverted Row: This bodyweight exercise targets the same muscle groups as the one-arm dumbbell row and can be progressed by elevating your feet or using resistance bands.
Pendlay Row: This barbell row variation allows for heavier weights and emphasizes the middle back and traps.
T-bar Row: This machine-based exercise isolates the middle back and rhomboids.

The one-arm dumbbell row is an essential exercise for developing a strong and healthy back. By understanding the muscles worked and mastering proper form, you can effectively incorporate this exercise into your fitness routine. Don't forget to challenge yourself with progressions and variations to continue seeing gains in strength and muscle development.
