 Do you think it's inappropriate to do leg exercises while you're online at the supermarket? I find myself every once in a while getting like when I'm standing there too long. Are you doing deep knee bends? What the heck? No, I thought that would really call attention to myself. I just try and like slowly when no one's looking like do a leg out, leg out, maybe leg back or just a few things just to kill some time. You ever see people doing that?
