What Muscles Does the Row Machine Work?

by Marie Mulrooney

Overview

If you want to add definition to your back before tank-top season, a rowing machine can be your best friend. This apparatus features three grip possibilities that each target specific muscles. For example, rowing with a wide grip in which your palms are down and your elbows are away from your body focuses primarily on your trapezius. A narrow grip in which your palms face each other, or an underhand grip where your palms face up, make your latissimus dorsi the prime mover. Regardless of which grip you use, your back is sure to get a workout.

Latissimus Dorsi

The latissimus dorsi (lats) is the most powerful muscle in your back. It’s responsible for any pulling motions that bring your elbow down toward your body from the side, or bring it from in front of your body toward the back. Using the narrow or underhand grip on a row machine will focus most of the load on your lats. These muscles also help on the wide-grip row, but to a much lesser degree.

Trapezius

The trapezius (traps) is another powerful back muscle that is responsible for most pulling movements. The traps sit a bit higher than your lats and the middle and lower portions of this muscle are most actively recruited when using a wide grip on the row machine. You may sometimes see a row machine with a wide grip that is dedicated specifically to working the traps and labeled as a “Trap Row.”

Elbow Flexors

The biceps brachii, brachialis (sometimes called the lower biceps) and brachioradialis muscles all work together to bend the elbow as your lats and traps pull backward on your upper arm bone, the humerus. All three row machine grips work these muscles.

Rotator Cuff

While the four small muscles of your rotator cuff are always working to stabilize your shoulder joint during any arm movement, the infraspinatus and teres minor, in particular, activate to assist with the pulling motion used on a row machine.

Rhomboids

Your rhomboids help pull your shoulder blades back and down, a critical factor in maintaining proper form throughout the row exercise.

Core Muscles

The natural tendency when using a row machine is to jerk back with the back muscles, using as much momentum as possible to make lifting the weight easy. Squeezing your abdominal muscles and the rectus abdominus, in particular, to press forward against the machine’s chest pad helps eliminate this bad habit, reducing your risk of injury and forcing your back muscles to work that much harder.
