I believe this is the stretch. Take note that the picture is my own creation, and it may be incorrect from how DLD planned the stretch. It still does stretch, however, so either way, give it a try.
I tried this stretch quickly about three days ago. By quickly I mean less than a minute. The following day I still noticed a little pull. I was impressed, so I tried it for longer and with more intensity. I awoke that night to use the bathroom, when I looked down at my
hanging member, it was the longest hang I've ever seen. And of course, 2 days later, I'm still sore.
And yes, the wrists are the size of the shaft.
