I never knew how susceptible to injury I was making myself by skipping shoulder day. I can't believe how much more control I have over my chest day lifts just by hitting all my shoulder day lifts from different angles. In addition I do a prehab / rehab rotator cuff routine 2-3 times a week. I am seeing huge benefits from doing this. Angles of movement that previously would have made me wince in pain are no longer giving me trouble.
But really I made this thread because I'm sure theres someone else out there who was like me - they love Arms and Back/Chest but the others they get them in when they can. Don't. Be. That. Guy. Especially after I tore my rotator I told myself I don't need to be doing shoulders. This was true for a while until my rotator cuff healed through time and rehab exercises. I hope to never miss shoulder day again. If you miss one angle of the body, lets say the front delt or side delt that a front raise or side raise would hit or an arnold press, what happens is you go to pick up some dumbbells and do a chest press and there is an angle out there that you are grossly unprepared to compensate for. This is how injuries happen and I wish someone had sat me down and told me this back in the day.
