The gymowner/ trainer I go to has a lot of shoulder injury guys come in. our 6 week training splits hardly ever has normal flat bench also no smith machine.
We utilize many press movements. Here are a few, my shoulders have never felt better.
Slight incline DB banded press, use of chains to load the top with a neutral bar for bench, assisted resistance band bench, free motion cable presses, chain weight elevated push-ups, hammer press machine.
