One year of hanging is a lot of time spent. More than half of voters had negligible gains, and only a minority - 16% has good gains, proportionately to the effort.
Hanging has been marketed as the ‘ultimate length technique’; results seem to show that what few of us were repeating from a long time is true: there is nothing magic in hanging, it is like any other PE techninque : it could work wonderful, it could not.
One year is a lot of time, yes, especially if you’re dedicated. But really, if you hang decent weight off of your dick 2 hours a day, that’s 730 hours or 30 days under tension. If your dick doesn’t respond to that with growth, then you’ve got a dick made of steel and you should quit PE altogether. If that doesn’t work, what will?
Disclaimer: I’m talking about proper hanging, i.e. knowing what you’re doing, using decent weights, riding the fatigue, targeting multiple angles (one by one of course) and eventually using a fulcrum.
