Pectoral Fly.

The squeeze, not the push.

In the bench press you push, and the triceps and front delts take a good share of the job before the chest is done. The fly squeezes instead, and with the elbow in a fixed arc the work stays in the chest from a full opening until the hands meet in front of you. You set the seat so the handles sit at chest height, take the 90 kg stack out into the stretch you actually feel, and spend no energy on balance. The machine takes 1350 × 1345 mm, is 1545 mm high and weighs 232 kg. The chest gets the bill alone.
