It’s The Process Not Just 1 Thing
Seeing posts asking what is the best…or the 1 thing… for results. As mentioned above, I think you need the right conditions AND routine. For routine the majority of my time is hanging tension, but I do a lot of other things each session as well, for different reasons; warm up, injury prevention, blood flow, stress angles & phases and recovery. So this includes ADS, wet and dry jelqs, stretches and a short pump or CR. My opinion is that the hanging does the most, but when you couple the other thing, then you are maximizing your efforts.
Time seems to be a big hurdle with everyone. When it is for me, and I have to only do one thing, I do the weighted ADS over everything else.
