A month ago, I sprained my L5-S1 from squatting and soon discovered that I had horrible hamstring flexibility. Since then, I've become somewhat obsessive about reading up on mobility, flexibility, prehab, and all that good stuff. Since I can't squat, deadlift, or do olympic lifts for a while, I have a lot more time to do other stuff.
I just recently read up on Eric Cressey's 3 Shoulder Saver articles and his rotator cuff article on T-Nation. I've had shoulder flexibility problems, but never had any shoulder pain. Anyways, I never knew about all the importance of balancing humeral external rotation with internal rotation, scapular depression and elevation, scapular repression and protraction.
For the upper body, all I usu. do are vertical pushing and vertical pulling movements (and dips for which I don't know the categorization). Basically, I'm wondering whether I should worry about all the stuff Eric Cressey writes about b/c I've never had shoulder pain in the past. I do a lot of shoulder mobility work and am going to add stuff I've read in Super Joints. To increase shoulder flexibility, I do a lot of shoulder dislocates and do kip swings.
From the CrossFit community, I've always heard that to have healthy shoulders, just have a lot of shoulder mobility and press stuff overhead. According to Cressey's chart on Shoulder Saver: Part 1, I do scapular protraction, scapular elevation, and humeral internal rotation exercises, but I don't do any exercises on the other side of the chart.
These trips to the doctor and chiropractor are wearing on me.
