The one arm dumbbell row is a powerhouse exercise for building a strong, muscular back. Whether you’re working out at home or in the gym, this move is simple yet incredibly effective at targeting your upper and mid-back, improving posture, and boosting strength.
In this post, we’ll break down the proper form, the muscles it targets, variations to try, and safety tips to get the most out of this classic dumbbell movement.
🔍 What is the One Arm Dumbbell Row?
The one arm dumbbell row is a unilateral strength training exercise where one arm pulls a dumbbell in a rowing motion while the other side is supported (usually on a bench). It allows you to isolate each side of your back and correct muscular imbalances.
🧠 What Muscles Does One Arm Dumbbell Row Work?
This movement engages multiple upper-body muscles, including:
- Latissimus Dorsi (Lats): The primary target; responsible for pulling your arm downward and backward.
- Rhomboids: Assist with retracting the scapula (shoulder blade).
- Trapezius: Stabilizes and moves the scapula.
- Rear Deltoid (Shoulder): Engaged during the pulling motion.
- Biceps Brachii: Assist with the lift and contraction.
- Core Muscles: Engaged to stabilize the body during the movement.
The one arm dumbbell row is a great compound movement that helps in both muscle hypertrophy and strength development.
