FerociousD,
That is a very difficult question to answer as we all respond differently to ligament/tunica stress. No one here wants to accidentally give you the wrong advise. However, based on all the reading I have done over the years it seems that the majority of the good gainers employ a less-is-more approach. Consequently, if I had it to do all over again I would hang 5-7.5 lbs for 15-20 minutes at angles between SD and BTC, rest 10-15 minutes between sets and do 4-6 sets totalling 1 to 1 1/2 hrs. If/when gains stopped I would switch angles to between SO and OTS. If gains stopped at all angles I would try increasing time. If still no gains then increase weight by 1 1/4 lbs (standard barbell increment). At the moment I think that increasing weight should only be done as the last resort. Thinking back now, my goal was to hang a lot of weight, thinking it would produce fast and big gains. My hanging gains have been slow and I have tried more weight and it does not help and instead it has hindered. There has been more anatomical discussions on Thunder’s since I started and from what I have read, connective tissue healing takes quit a while to heal and that is just one injury. It would seem that compounding injuries (daily heavy hanging) would eventually confuse the healing mechanism resulting in severe inflammation. Minor healing would occur while the tissue is retracted. This healing would be disorganized and overly thick. Results, slow/no gains, limited long term results. On the other hand, when hanging light and long the healing is more balanced with the lengthening process such that only a minimum of connective tissue strengthening occurs. My $0.02 worth.
Before you start I suggest you carefully measure (ruler on top) your starting size and always take the biggest measurement. You will need to be confident that as little as 1/16” gain has occurred over a months time. That might not sound like much but if you could gain at least that much per month, you will have gained 3/4 ” in one year. I doubt that anyone on this forum would be disappointed with that kind of gain. So again, measure carefully.
Sorry to ramble but I do some of my best thinking when I am trying to answer other peoples questions.
