I have been doing some heavy bench press for years (and dips here and there) and mine pops everyday more than twice. If I sit in certain positions where my chess or my shoulders are folded into each other, I can usually stretch out with my arms and pop it. It's a 'must' because I can really feel it if I don't pop it. Sometimes though, it hurts after I do it. Not sure if I can get rid of this. It's gone away for awhile (not sure how or why) and come back. But my friend started getting it when he worked out with heavy bench press.
