Which should you choose?
The Barbell Skier lets you load the heaviest weights and progress in small, steady jumps. The Cable Supine Reverse Fly keeps constant tension on the muscle through the whole range of motion. 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 delts adapting.
