The last few weeks, I've been getting all these really loud pops, and cracks, when I do my exercises. When I reach overhead with my left arm, sometimes I get this weird ripping sound, sounds like someone pulling tape off of something. I guess it's just muscles coming apart. Crazy.

A few days ago my wife was in the other room and she heard this huge crack. She asked me if I was OK. It was just my shoulder popping, didn't hurt. Crazy stuff. I'm assuming it's good, if it doesn't hurt.
