How to Do Machine Chest Flyes

  • Adjust the the back support and handles, so that you can grip the handles in shoulder height, and get a long range of motion.
  • With just a slight bend in the arms, push the handles forward until they meet in front of your body.
  • With control, let the handles go back to the starting position.


Machine chest fly is an isolation exercise for the chest and front deltoids. Compared to dumbbell chest flyes, the resistance curve in machine chest flyes is more evenly distributed, and you have more of a constant load on your chest muscles throughout the whole range of motion.
