The top left photo is called a Barb Wire, the goal is to be able to stretch out your body perpendicular to the pole, which I am attempting to do in the bottom photo. The bottom arm, with its elbow dug into the ribs and the abs are what makes this trick possible, like most tricks, it is a little more difficult to do once up on the pole vs being on the floor. Since I live to impress people, I prefer to just do it up on the pole, can't wait until I have this one mastered.
