Reverse Pec Deck
Muscles worked
Instructions
- 1Adjust the handles so that they are fully to the rear. Make an appropriate weight selection and adjust the seat height so the handles are at shoulder level. Grasp the handles with your hands facing inwards. This will be your starting position.
- 2In a semicircular motion, pull your hands out to your side and back, contracting your rear delts.
- 3Keep your arms slightly bent throughout the movement, with all of the motion occurring at the shoulder joint.
- 4Pause at the rear of the movement, and slowly return the weight to the starting position.
About Reverse Pec Deck
The reverse pec deck machine isolates the rear head of the deltoid on a guided path. Seated facing the pad, chest braced, you spread the arms backward while squeezing the shoulder blades, then return under control. The machine removes the need to brace the back and manage balance, letting you focus entirely on the rear-shoulder contraction, a muscle that is often hard to recruit. It is an excellent choice for rebalancing a posture dominated by pressing. Take the handles at shoulder height, keep the elbows slightly bent and avoid shrugging.

helpFrequently asked questions
Reverse pec deck or dumbbell rear fly?expand_more
The machine guides the path and removes lower-back cheating, while dumbbells demand more stability. Both target the rear delt.
Should I grip the handles high or low?expand_more
Handles at shoulder height give the most horizontal angle, which best isolates the posterior deltoid.
Should I fully straighten the arms?expand_more
No: keep the elbows slightly bent and fixed throughout. Fully straight arms change the movement and stress the elbows; the idea is to spread the arms, not lock them.
