I have always had this light popping noise in my shoulders(most of the time with no pain and sometimes with a little pain) in my right arm when I do any over the head "push up" or "pull down" exercises. When I was younger 18, and in great shape( 5'9" 165# 5%BF) I asked my doctor about it and he said not to worry about it. Im now 30(5'9" 190# and im sure at least 20%BF) and trying to get back in shape. My right shoulder is doing the same popping but now it hurts. Will this get better over time or am I predisposed to shoulder problems(my left pops a little but it never hurts). Will the YTWL workout/warmup help my problem? Thanks for any advice.
