This is not an exercise for a newbie, you do not want to get the cart ahead of the horse. It is a bit of a misnomer to label this “erect hanging,” in my opinion you cannot hang erect due to physiological factors. The excessive force will cause your erection to subside quickly. You can secure the hanger to the semi-erect penis and attach weights and you will see erectile pressure being reduced quickly, it is just nature taking over to prevent a broken shaft.
I engorge to accept as much blood as possible and then apply the hanger in a way that gives optimal size to the glans, to enlarge the glans requires increasing forces in a controlled manner and this hanging routine does that better than anything that I have found. It works quite well, I have a very nice shaped large symmetrical head. It certainly is much easier on the unit than clamps from my experience. I have been hanging for quite some time and use 15lbs for this particular process, my glans has not suffered any ill effects or discoloration.
If you have a head that responds properly to Uli type exercises and balloons proportionately to the shaft, you may benefit from this exercise. Some people have glans that do not manipulate well due to genetics and circulatory factors and cannot take advantage of head enlargement.
