Machine rear delt fly

The machine rear delt fly is an exercise targeting the rear head of the shoulder muscle or deltoids, as well as the muscles of the upper back. It's sort of the reverse of the machine chest fly, and is sometimes performed on the same machine, but facing the opposite direction. Because it targets such small muscles, this exercise is usually performed with light weight for high reps, such as 10-15 reps per set or more.


  1. Adds size and strength to the posterior deltoids
  2. Easy to learn and master the technique
  3. Helps develop bigger, more balanced, and healthier shoulders
  4. Great burnout movement on shoulder day
  5. Works the rhomboids and lower and middle traps
