Setup

  1. Position a flat bench in the center of a cable crossover machine, ensuring it is perfectly aligned between the two pulleys.
  2. Set the pulley heights to roughly shoulder level when seated.
  3. Sit firmly against the bench with your feet flat on the floor for stability.
  4. Grip the handles with a neutral grip (palms facing each other) and bring them to the starting position with your arms extended out to the sides.

How to do it

  1. Exhale as you bring the handles together in a wide arc in front of your chest, maintaining a slight, fixed bend in your elbows.
  2. Squeeze your pectoral muscles hard for one second at the point where the handles meet.
  3. Inhale as you slowly reverse the movement, controlling the weight back to the starting position until you feel a deep stretch in your chest.
  4. Maintain a controlled 2-1-2 tempo (2 seconds out, 1 second squeeze, 2 seconds back).

Form checklist

  • Keep your chest puffed out and your shoulder blades retracted against the bench throughout the set.
  • Maintain a consistent slight bend in the elbows; do not allow the movement to turn into a pressing motion.
  • Avoid letting the weights touch the stack at the end of the eccentric phase to keep constant tension on the muscle.
  • Ensure your wrists remain neutral and do not bend backward under the weight of the cables.

Pro tips

  • Focus on bringing your inner biceps toward your sternum rather than just moving your hands to maximize pectoral recruitment.
  • Imagine you are hugging a large tree to maintain the correct arc and isolation mechanics.

Make it harder

  • Incorporate a 3-second isometric hold at the peak contraction of every rep to increase time under tension.
  • Perform '1.5 reps' by bringing the handles together, returning halfway, squeezing back together, and then returning to the full stretch.
