Steps

  1. 01

    Adjust the seat so the handles are about chest height; keep the back on the pad and feet flat.

  2. 02

    Hold both handles with a slight, mostly fixed elbow bend and shoulders away from the ears.

  3. 03

    Bring the arms together in front of the chest along the machine path, pause briefly, and avoid lunging forward.

  4. 04

    Open under control within a comfortable shoulder range without letting the stack slam.

Common mistakes

  • Poor seat height causing shrugging or excessive backward shoulder travel.
  • Turning the fly into a press by changing elbow angle, or slamming the stack.

Before logging, know the load basis

This exercise is logged as:

Machine stack
Record the stack number shown on that machine; comparable on the same machine only · Load + reps
