What It Works

The seated reverse fly trains the rear of the shoulders and the upper back. Sitting and hinging forward takes momentum out of the movement so the small muscles can do the work.

In everyday life this pattern helps you pull your shoulder blades back — sitting tall at a desk, opening your chest to carry bags, or reaching behind you.

How to Perform

Sit on the edge of a bench with a light dumbbell in each hand. Hinge forward from the hips so your chest is over your thighs and your back is long. Let the dumbbells hang under your shoulders with a soft bend in the elbows.

Raise the arms out to the sides in a wide arc until they are about in line with your torso. Squeeze the shoulder blades together. Lower under control. Don’t shrug or swing.

Setup & Movement – Quick Bullets

• Sit and hinge forward with a long back
• Dumbbells hang under the shoulders
• Soft bend in the elbows — keep it
• Raise the arms out to the sides
• Squeeze the shoulder blades
• Lower under control

Common Mistakes

Common issues include using too much weight and swinging, bending and straightening the elbows (turning it into a row), shrugging, and rounding the upper back.

Watch Out For

• Swinging the weights
• Turning it into a row
• Shrugging the shoulders
• Rounding the back

Quick Fixes

• Use lighter dumbbells
• Think “open the arms,” not “row the weights”
• Keep a consistent elbow bend
• Stay hinged and still through the torso

Key Cue

Open the arms. Squeeze the back.

This is a small rear-shoulder raise. If you have to heave the weights, they are too heavy.

Scaling

Easier: Use lighter dumbbells or a shorter range.

Harder: Pause at the top or slow the lowering phase.
