Some interesting facts taken from the Bib Hanger web site that I felt would be relevent:
“After hanging for several months, a good stress is to hang under each leg, over the side edge of the chair while seated in an almost BTC position. This greatly stresses each SIDE of the ligament bundle, dividing and conquering. Then, a normal BTC hang will stress the MIDDLE of the bundle. The sides are already longer from the side stretch. So the middle then has to take the load. This is just one example.”
“So when hanging straight down or BTC, the tunica may not be affected at all, taking none of the stress. Only the ligaments. Now, as the angle rises, say to hanging straight out, the ligaments take less and less stress and the tunica takes more and more stress. So then when hanging straight up (over the shoulder), most (if not all) will have all the stress on the tunica and the anchor points within the body, and none on the ligaments. Further, hanging over the legs will stress the sides of the tunica, and the anchor points within the body on each side.”
“If you are very sore in the pubic bone area (the ligaments), it is time to work on the tunica and anchor points. This means over the shoulder and legs or straight out, 90 degrees from the body. If the tunica (shaft) and area above the testicles is sore, it is time for straight down or BTC.”
I have posted these quotes in response to my own questioning hoping that it MAY guide or answer some other questions another hanger or potential hanger may have about the different positions.
Hope it helps! TT
