Lots of great advice here, thank you! Yesterday afternoon I worked on internal rotation with a barbell anchoring my shoulder down. Then worked my pecs with the lacrosse ball and reset my shoulders to the back of their capsule. The combination of those 3 things seemed to help when I retested doing some very light BB OH pressing. First rib mobilization sounds very intriguing as well. I’m going to make a habit of doing these things and see how I progress from here on out. Thanks for your guidance!
