Which should you choose?
The Cable Decline Fly keeps constant tension on the muscle through the whole range of motion. The Single Arm Push-Up needs no equipment and scales through leverage, tempo and reps. 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.
