thanks for the info Mike, i'll try them out.
That's right, I don't know why I was thinking elbow, hmm. But anyways, i'll see how it goes. I've tried them out before, and i've never had any problems with my shoulders, but then I read up on them and stopped doing them. I do a lot of chinups in my workouts, and exercises that work my tricep and back, so maybe that will help with my ability to do dips pain free. When I used to do them, i would go down till my elbows reached a 90 degree angle, then i would go all the way up. They're tiring, but i'll see if they help and if i begin to notice pain, i'll stop doing them.
Thanks for your help. Would you recommend 3 sets of 10-15.
