I would like to know your thoughts, as I have heavily taken up hanging again too. I use a vac-hanger, and have been doing 10lbs, for a long time beforehand. As I got into it again, I soon upped that 10 to 12.5lbs. I try to do 2 sets a day of 30 mins, morning and night. I also use heat, and have yet to see any gains.
