Exercise guide

Cable Lying Fly

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

The cable lying fly provides constant tension on the pectoral muscles throughout the entire range of motion, offering a superior peak contraction compared to dumbbells. It is highly effective for isolating the chest and improving the mind-muscle connection without the stability requirements of free weights.

Setup

  1. Place a flat bench in the center of a cable crossover machine, aligned evenly between the two low pulleys.
  2. Set both pulleys to the lowest height setting and attach D-handles to each side.
  3. Grasp the handles and lie flat on the bench with your feet firmly planted on the floor for stability.
  4. Position your arms out to the sides with a slight bend in the elbows, palms facing up, so your hands are level with your chest.

How to do it

  1. Exhale as you pull the handles together in a wide arc, bringing them toward each other directly over your mid-chest.
  2. Squeeze your chest muscles hard at the top of the movement, ensuring your hands do not quite touch to maintain tension.
  3. Inhale and slowly lower the cables back to the starting position in a controlled arc until you feel a deep stretch in your pectorals.
  4. Maintain a steady 3-0-1-1 tempo: three seconds on the way down, a one-second squeeze at the top, and one second on the way up.

Form checklist

  • Keep a fixed, slight bend in your elbows throughout the movement; do not allow them to flex or extend.
  • Keep your shoulder blades retracted and pinned against the bench to prioritize chest activation over the front deltoids.
  • Avoid arching your lower back excessively; keep your core engaged and spine neutral.
  • Ensure the movement occurs only at the shoulder joint, keeping the rest of the body still.

Pro tips

  • Think about bringing your biceps toward each other rather than just your hands to maximize the contraction of the inner chest.
  • At the top of the movement, slightly rotate your pinkies toward each other to further engage the upper and inner pectoral fibers.

Make it harder

  • Add a 2-second isometric hold at the peak of the contraction on every repetition.
  • Perform a slow 5-second eccentric (lowering phase) to increase time under tension and muscle fiber recruitment.
