Most of my shoulder issues went away when I reversed the order of my delt exercises. Instead of starting with my main exercise, standing overhead presses, I now do all the isolation exercises first ( side lateral raises, reverse flys, exc ) then I finish with the standing ohp. Little humbling at first not being able to press as much weight but after a few weeks of doing it like this I started noticing new growth in my delts, and a lot less pain. Only other exercise I gave up on was flat barbell bench, they are probably the actual culprit of my shoulder issues to begin with. I still like the bar, i just switched to decline instead of flat, somehow they don’t bother my shoulders . I do the standing ohp on the smith machine, at 5’8 inch im short enough to be able to get to full extension without hitting the top.
