Over a decade ago, I dislocated my shoulder. Hospital trip to get it shoved back in and walking around for a week with my arm in a sling. Since then, once or twice a year, I'll over-extend too quickly and it'll pop back out. The wince of pain is usually enough for the muscles to spasm and pull everything back together, leaving me with a couple days of bruised muscle.
Fast forward to present day, I started eating Paleo/Primal/PHD back in mid-January. Been getting my vitamin D and my vitamin K2, my magnesium, and my leafy greens. And I finally took the plunge and signed up for some fitness classes (yes, strength and conditioning, not cardio).
Anyways, class starts off with some warmup calisthenics including jumping jacks. Jump. Jump. Pop. Wince. Ow. Hmm, maybe it was just a fluke? Jump. Jump. Pop. Ow. Okay, not a fluke. (Rest of the class went just fine ... other than pointing out how generally out-of-shape I am.)
So, does anybody have any tips, tricks, pointers, guides, foods, or exercises I should be doing to strengthen up that shoulder (a decade after the fact)?
