Honestly man, my shoulders were messed up for years. I’d do some stuff and get a little better for awhile then slide back into bad posture and sore, restricted shoulders.
I was doing part of what it took to get better, working/strengthening the mid back “posture muscles” and stretching the tight stuff (pecs and biceps) and that would get me unslumped for awhile, like 2/3 of the way there.
What I was missing was work for the actual shoulder joint (like the tissue around the ball and socket) to build up the ROM and strength of the joint. I learned that when your posture sucks and your shoulders are slumped you only use some of the tissue around the joint. The rest goes unworked so your body doesn’t want to use that tissue, that restricts the ROM of the joint and as a result your shoulders can slump to make up for this. Or your posture gets bad because your body is trying to put your shoulders in a position to get the most out of your extricated range of motion.
Anyway, I started doing stuff like this after I had my mid back fired up and my shoulders unslumped. To “stress” or train shoulder joints. After like 4-6 weeks I had huge improvements.
Or the rotational move at 2:00
