@EyeDentist Have you found a different exercise now that you prefer for chest or is pec deck still your favourite? I’ve ignored some shoulder impingement for a long time and now it’s really limiting my repertoire of pain-free chest exercises. For now, I’m taking focus off of training chest so that I’ll be able to accurately gauge if an exercise actually does cause me pain or not as right now almost everything involving the chest seems to illicit a lot of tightness at the front of the shoulder.
Doing inverted rows I saw the visual discrepancy between how much more developed my pec was on the non-affected side 
so ignoring the pecs isn’t a long-term solution.
