Thanks Sacred, this is the kind of info I am looking for — specific comparison of gains on no manual exercises routines versus routines that incorporate manual exercises. I hope more people will have similar data to share too.
One of the reasons I ask this question is that I have sense that everyone just assumes that, if nothing more, jelqing is at least indispensible compliment to other exercises. Yet, I have also heard things that have made me wonder, alongside my own reluctance to just accept things without strong specific evidence to support it, whether or not jelqing is really as essential as everyone assumes. In particular, I’m intrigued by Dr. Adams’ opinion, related in the ChemPE thread, that jelqing is not an exercise he recommends because he feels it’s likely to promote tunica toughening too much.
I realize that jelqing is awesome for improving erections, and I realize that people get great gains from manual stretching. However, I wonder if, between clamping and hanging, one couldn’t possibly get at least most of the growth capability available through the manual exercises, without as much effort, inconvenience (lubing, cleanup, having hands occupied whole time, etc). In other words, I know manual exercises are awesome. However, I am very interested in finding out what is known out there about how effective routines that don’t use manual exercises can be nonetheless.
