Which should you choose?
The Cable Fly keeps constant tension on the muscle through the whole range of motion. The Floor Fly (With Barbell) lets you load the heaviest weights and progress in small, steady jumps. If your gym has both options, neither is a wrong choice: pick the one that feels strongest through a full range, and swap after 6 to 8 weeks to keep the pectorals adapting.
