NASM-CPT, CSCS certified trainers. Every guide is built from peer-reviewed research and real coaching experience.
The chest-supported rear delt fly is the purest rear deltoid isolation possible. Lying face-down on an incline bench eliminates momentum, lower back involvement, and every other variable that lets you cheat. Your rear delts do all the work with no assistance.
Set the bench to about 30-45 degrees. Let your arms hang straight down with a slight elbow bend. Raise by driving your elbows outward, not by pulling your hands up. If your traps burn before your rear delts, your elbows are traveling up instead of out—lower the weight and fix the path.
What muscles does the Chest-Supported Rear Delt Fly work?
Why This Exercise Works
The chest-supported position eliminates your lower back from the equation entirely, making this the purest rear deltoid isolation possible. Unlike bent-over variations, you cannot cheat with momentum or use your spinal erectors to assist.
This makes it ideal for lifters with lower back issues or anyone who finds their back fatiguing before their rear delts during bent-over work. The bench does all the stabilization work, so you can focus entirely on the target muscle.
The common error is going too heavy and shrugging the weight up with your traps instead of leading with your elbows out to the sides. If you feel your upper traps burning before your rear delts, reduce the weight and focus on the elbow path.
