Marinera you have convinced me to give light hanging for many sets a day a try and I was wondering how much weight would you suggest I use for the next few months?
If you have a lot of time, go for it. I think you should start with about 1 lbs. Depending on the kind of hanger you are going to use, it will require some hours to learn how to properly do hanging. After this first stage, I think you can raise the weigth adding very very little when you think you need it.
I have to say that in my personal views hanging with so little weight is not a good choice when you can use an extender or similar devices. You can have a walk or go to see a movie wearing an extender or an Ads, (first times you’ll not have the balls, but after a while you’ll be able), not the same if you do have an hanger with weigths attached to your penis.
Also, you can easily stretch in any direction with an extender, where if you are hanging you do need a pulley.
I would switch to weights whan I have no gains anymore with low tensions.
Anyway, it will not make that much difference in terms of gains, so if you like hanging many hours with light weights go for that.
