Man that side advice in the OP on hanging from the bar is pretty good, great stretch for my spine and lats. Doing it every day now. One cool trick is Jutting your head forward while hanging, keeping your chin up. Cracks your back and feels great. It's actually helping me hang longer because I am so distracted trying to get that deep crack, and once I get it, the relief powers me through for a while longer!
