Been trying a few new things, spreading out more days (2 rest days, instead of one) between chest and shoulders, that is definitely helping. I also took some pointers on the internet to avoid certain 90 degree angles, especially with should pressing with the dumbbells, putting my elbows a little more forward seems to be a lot better, also bringing my elbows in more to my body when benching, but its a balancing act between finding the right positions and still feeling comfortable. As long as I don't tear anything I'll keep the workouts going, but the left shoulder (this is the one that is holding me back) was hurting more after Mondays benching, better today when doing shoulders after a few days of impingement exercises/stretches.
