Voodoo floss!!!! Get it from rogue fitness and google Kelly Starrett and golfer's elbow. He has WOD stuff on YouTube to help with it. Also shoulder dislocations with a broom stick or PVC pipe, lacrosse ball into the scapula, lat, tricep, and pec insertion points. Take a PVC pipe or dough roller and have someone work that into your lat, touch your palms together and try to push your elbows to touch at the same time. Sit down and use your knees to help drive elbows together. On squats use a wide thumbs around grip.
