A few months ago I was working through the start of a concept - an Armbar from the Turtle position, when you are in front of the guy, and you have an underhook on one arm (something that I had picked up from wrestling). The reason I figured there was an armbar was because the arm was hinging in the same motion except the guy was flipped vertically on his knees not his back.

So I messed about with it for a few nights and spoke with Ahmad and Mikey, 2 senior belts, one Saturday about the concept too but it was decided it would take too long to achieve and not be a very high success rate but was encourged to keep exploring it.

I have pulled a few armbar's from Turtle position now and am still trying to discover the details that will increase the efficiency of it. However as we know there are many variations and tonight Renzo Gracie posted the following video which explains how he has developed the concept and explains the technique and how to do it without injuring your shoulder (which I of course found interesting)...so I thought I would share
