@aRay: I've been training for about a year. The problem is inflexibility in the shoulders coupled with occasional rotator cuff and mid back pain. It's certainly nothing that warrants surgery, but the shoulder issue is something I want to sort out immediately.
This is also hardly helped by the physical requirements of a job in IT. I've taken to regular stretching and mobility work just this past week, which includes shoulder dislocates with a resistance band, planks, hip flexor and glute stretches, pec stretches, quite an array of stuff.
