What the hell do you mean! LoL- just kidding.
Gains from AI stretching - I’d say about 3/4 inch. I haven’t measured in a while really cause I’ve gotten what I was after.
I don’t think I got much from 30 second stretches - actually I didn’t get much from 30 second static stretches on major muscle groups either. Most of my other gains came from jelking - but only when I skipped days often.
Honestly, I don’t know much about hanging - the main turnoff about it to me is the time factor however many people have made spectacular gains from it as evidenced by posts here of many of its practitioners. Plus it seems dangerous - even though the reality is that the rate of injury is lower that jelqing probably - still I wonder about the long term effects of hanging and sometimes of pe on the penis (besides initial size increase) in general. I definitely will stop soon.
I think with AI what is happening is that you are successfully stretching muscle because you are avoiding a reflex which prevents injury to muscles due to overstretching. And maybe this in turn allows you to further stretch other structures. That could be wrong however I do know that you could right now increase your flaccid hang by half an inch in a few minutes with 2 second stretches. From there in time, erect legth happens it seems.
Also, you know how when you do 10 - 30 second stretches and the dick gets progressively harder and you get less stretch? This happens to much less an extent with 2 second stretching which I think gives a lot more flaccid stretch like hanging actually. I think it really takes you through the stages of flaccidity very evenly and very, very slowly.
One other thing I do - and I don’t recommend it - its just my own weirdness - on my last set, I’ll get my dick somewhat hard deliberatelly and do a mild set of 10 - 2 second stretches. I’m very careful - you could fuck your dick up with this. I do it much gentler than the flaccid two second stretches. It seems to make a greater erect length right off when I use to measure it. However, I really hesitate saying this as I dont want no one getting hurt by my recommendations.
I think the real length gain is happening during flaccidity anyway,
I do day on day off jelking because it stopped the impotence I was having - my guess because of what was excessive jelqing for me. The jelqing itself has yielded me a solid inch. I do all my measurements nbp - and Im very careful. I stopped doing bp measurements when I was getting growth bp but not nbp which to me just made that measurement useless in terms of getting actual useable dick growth - useable meaning what I could yield to an eye. But its probably better to measure as many ways as makes ya happy.
