How much time are your hanging sets? How many do you do? How much weight? Do you use heat (rice sock, etc)?
I know everyone is going to get shocked about this, but I hang 1h-1h30min daily in one set. Yes, one set. I don’t have any problems hanging 1h30min in one set, but when I started vacuum hanging, I only did 20-30min sets. I warm up with hot towel first and then fill coke bottle with hot water and keep it on my penis when I hang. I only apply heat for 15-25mins and then let my penis cool down.
I’m still using 5lbs. I feel very stretched after hanging, actually I just finished 1h hanging(In one set :-P ).
