When I was 37, I had a minor rotator cuff injury and since then I have been a little obsessive about the feelings in my shoulder - I have clinical OCD BTW which is a fucking nightmare - Anway, I haven't had any injuries to my shoulders since, but I also want to continue on a shoulder preservation program but not get too exotic; I've been doing external rotations x 3 once a week in recent history.
I also warmup my delts, rotators and mid traps before upper body workouts. I've also started (today) with another exercise that helps the shoulders, (don't know name offhand) - flat bench lying down, dumbbells, arms straight up - exercise executed by ONLY contracting the shoulders toward the ceiling, holding it for a second, then the eccentric.
I have seen many articles and exercises about shoulder health, exercises recommended and not recommended; I've also found more contradictions than I'd like to.
So with that, what are y'all's (Southerner's second person plural possessive with the unusual double apostrophe repped in the Southern version of Merriam Webster) approach to shoulder "support" movements, if any. Too often I get paralysis by analysis when I research this stuff on my own and subsequently feel like I know less than before said research.
