Very nice article Bernie.
I have some kinda shoulder problem myself. I had slight shoulder pain for a few months, then one day, it started hurting pretty bad (kinda sharp pain). Funny thing is this pain started about 24 hrs after a workout (di bi's and back that day, guess the back stuff could have put the strain on it). Didn't have pain during the workout or that night.
So I took off 1 month and things felt better, but it still felt a little odd in my shoulder (pain was pretty light, more annoying than anything). Now I've been working out for about 6 weeks and trying to take out some excersises that could hurt and I also do stretches and some of these RC strengthening excersises.
What I'd like to know is if some of you don't really have problems during the workout (or very minimal pain), but maybe more pain the next day or two. This happens to me, and I thought it may be out of the ordinary?
