The problem with weight and time is one answer doesn’t fit us all. One person might need 30 pounds before they see any gains. This is probably the rare exception.
My concern is hanging should be something you do secondary to something else. I am typing, studying, learning, playing games, watching TV and the hanging itself doesn’t really get on my mind that much.
To me that is the real power of hanging. If you can multitask then hanging isn’t this huge time sink.
I have done hanging just for the sake of hanging and it is hard to stay motivated. That is why I admire your perseverance. To be in that amount of pain session after session I don’t know if I could have done that.
My main concern would be injuring myself.
If you can spend 4 hours hanging everyday then more power to you. I just think I would go out of my mind if hanging was the primary thing I was doing. But if you can do homework or learn job skills for 4 hours while you are also happening to make your penis bigger then to me that’s is the best situation.
If you get a chance go to Bib’s forum. I know you bought the Male Hanger but you should still be able to read around. In the basics section find the post on managing fatigue. To me this is the gold standard. This is what I aim for. Now I have still gained during periods of time where I didn’t hit fatigue like this. However, I have a very high exit point and I am under the belief that this is why I have had easy gains. It is just a pattern that I have been noticing with others.
But the main thing is to build up to a weight that you feel that you start watching the clock. You want to get to that feeling of strain/discomfort within 2 sets. This isn’t pain. This is more of a sense of I don’t think I can take much more. Then you drop a pound or 2. If the feeling persists you drop a little more. Usually a couple pounds and the feeling goes away. However, by the next set or maybe even later in the same set the feeling comes back. Now you drop another pound or 2 again. You keep on doing this throughout your session. You are trying to ride that level of fatigue all the way down.
Now Bib recommends that if you get to half of your starting weight and you still have more time to hang, now is a good time to change angles. Now start moving up the angles.
If you get a chance to try this I am guessing it might take you a little while to get a feel for that fatigue feeling. You probably have conditioned yourself for pain that the fatigue feeling won’t feel like it is doing anything for you.
