So about a month ago, this weird thing started happening. If I was driving a car, at a computer, watching tv, or anything that somewhat had my chest muscles close together, when i would lean far back or just spread out my chest, something in the center between the pecs would crack. I don't know what it is as it's never happened before until a month ago, and happens every day now. It doesn't hurt any though.
Another weird one, before I started Poliquin's S-A program, when I would db bench press, i'd never hear spinal cracks when i leaned back from the sitting position. Now on the first set of every DB bench press, as i start to lean back, i hear my whole spine crack in different places. It doesn't hurt and never happens on the next 4 sets, but I am just curious why it is happening to begin with.
Thanks for any help.
