The Ready State Virtual Mobility Coach is like having a virtual Kelly Starrett in your pocket.
Not sure about your exact problem, but they way you describe it would make me spend a ton of time stretching and mobilizing the chest. I’ve found that my chest is so tight it restricts much of my over head movements. After aggressively stretching my chest I found that my biceps got super stretched. Might help you or maybe lead you in the right direction. http://flic.kr/p/ePGZBz
