I've always been amazed at how the human body can change and adapt. Almost like kinky physiotherapy!

This made me think about single sleeve armbinders. I'm told very few men are flexible enough to be put into one. In most Bondage videos you see the subject is a woman and a very flexible one at that.

I wonder if it was possible to have your arms secured behind you with belts at upper arms, elbows and wrists several times a week for an hour or two (with tension increased several times during the session) if you would eventually be able to reach the goal of elbows touching?

As I type this it strikes me that the same might apply to the strappedo position as well. You see video's of women bent over with their arms very nearly vertical while I can barely achieve a bit past horizontal.
