RC was killing me, real bad pain.
Hey bro, I saw an exercise on another forum you should try for your RC. I can't access it here at work, but I'll edit this post with it (or link you) when I get home.
Basically, as I remember it, you use a broomstick (or similar) and hold it out in front of you, and use a wide enough grip so you can bring it up over your head and behind your back. You can also use a rolled up beach towel (if you can get one that's long enough). Some have found this to be a little easier if your shoulders are horribly inflexible.
One rep is from in front to behind to back in front. Do 50 reps once a day. Warm up some first - rotate your arms 20 times each direction to warm up your shoulders. Obviously if you are doing shoulders that day, you would be nice and warmed up to do these right after your workout.
Picture arms straight out in front of you about shoulder height. As you're holding the stick, rotate up over your head to again about shoulder height behind you (if you can't reach that point, keep working until you eventually do).
Here's the rest of the info:
Keep your arms STRAIGHT all the way through the reps. Do this exercise carefully/controlled and slowly, don't just whip through it. If your hand is slipping off the broomstick even with the widest grip, or you cant bring your arms over and keep them straight and they start bending on you, you have some serious shoulder inflexibility and need to work this hard and get up to speed (or you could just need a longer broomstick too). Push into the stretch as you go along toward the 50 revolutions, your chest will be pushing outward and your shoulders rolling back. Your shoulders are going to blow up with so much blood its going to be incredibly painfull pumpwise. Do this once a day at nite as many times a week as you can. Sometimes I have people do it every single day, but every time you do it try to move your grip inward (thats the key). Its' going to be very hard to do but try your best to move your grip inward for the next 2-4 weeks and your range of motion with shoulders will increase dramatically and any impingement and the majority of other problems should be gone in 2 weeks.
Try to move your grip in as you are doing the 50 revolutions--start off with a stretching but relatively easy 10 to warm up some, then try to move your grip in even by a centimeter if you can for the next 20 revolutions and then at 30 try to move the grip in another centimeter. Really try to push what you can do stretchwise once your warmed up here. This sounds easy but your going to be cursing after you get to your 25th revolution. I've cured too many shoulder problems with this simple movement now its pretty ridiculous. This and a menthol rub applied liberally daily and before sleep has cured alot of shoulder/bicepital tendonitis.
