Reverse Dumbbell Flyes are a strength exercise performed by bending at the hips with a flat back, holding dumbbells, and raising your arms out to the sides in a reverse fly motion to target the posterior deltoids. The primary purpose is to strengthen and build the rear shoulders, improving posture, shoulder stability, and upper back development. Main muscles worked include the posterior deltoids, rhomboids, and trapezius; it's ideal for athletes, bodybuilders, or anyone addressing rounded shoulders, using just a pair of dumbbells.
How to Perform Reverse Dumbbell Flyes
- 1Stand with feet shoulder-width apart, holding a light dumbbell in each hand with palms facing in.
- 2Hinge at your hips to bend forward until your torso is nearly parallel to the floor, knees slightly bent, core braced, and back flat.
- 3Let dumbbells hang straight down from your shoulders with arms extended, elbows slightly bent.
- 4Inhale, then exhale as you squeeze your shoulder blades together and raise the dumbbells out to the sides in a wide arc until arms are parallel to the floor.
- 5Pause briefly at the top, focusing on the rear shoulder contraction.
- 6Inhale as you slowly lower the dumbbells back to the starting position with control.
- 7Repeat for desired reps, then stand up straight to finish the set.
- 8Key form tips: Keep a neutral spine—avoid rounding your back; use light weights to prioritize rear delt squeeze over momentum; elbows stay slightly bent throughout; if lower back fatigues, reduce range or weight. Common mistakes: swinging the weights, shrugging shoulders, or flaring elbows too much.
