Exercise guide

Cable Fly With Chest Supported

  • Intermediate
  • Isolation
  • Rep-based
  • Chest
  • Shoulders

The chest-supported cable fly isolates the pectorals by using an incline bench to stabilize the torso, eliminating momentum and ensuring constant tension throughout the range of motion. This variation is highly effective for targeting the inner and upper chest fibers due to the stable base and cable resistance profile.

Setup

  1. Position an incline bench (set to approximately 45-60 degrees) in the center of a cable crossover machine.
  2. Set the cable pulleys to a height level with your mid-to-lower chest when lying on the bench.
  3. Grasp the handles and lie face-forward (prone) against the bench with your chest firmly supported and feet planted wide for stability.
  4. Start with your arms extended out to the sides, palms facing inward, and a slight bend in the elbows.

How to do it

  1. Exhale as you bring the handles together in a wide arc in front of your chest, focusing on squeezing your pecs together.
  2. Maintain a fixed, slight bend in the elbows throughout the entire movement to ensure it remains an isolation exercise.
  3. Inhale as you slowly reverse the movement, controlling the weight back to the starting position until you feel a deep stretch in the chest.
  4. Perform the movement with a controlled tempo, pausing for one second at the peak contraction.

Form checklist

  • Keep your chest glued to the bench pad at all times to prevent swinging.
  • Ensure your shoulders remain retracted and depressed (down and back) to protect the rotator cuff.
  • Avoid turning the movement into a press; keep the elbow angle consistent.
  • Focus on bringing your biceps toward each other rather than just touching your hands.

Pro tips

  • At the peak of the contraction, imagine trying to touch your elbows together to maximize pectoral shortening.
  • Use a 'thumbless' grip if it helps you feel more engagement in the chest and less in the forearms or biceps.

Make it harder

  • Incorporate a 3-second isometric hold at the point of maximum contraction on every rep.
  • Perform a '1.5 rep' style where you go to full contraction, halfway back, back to full contraction, and then all the way down.
