If you don't have the strength to pull straight up from the ball, a right heel hook is good, or loop your right calf over the triangular outcrop that the ball is hooked to, and that will get your body in position to grab and pull up with your right hand. After that it's basically over.
Some buddies of mine found some beta that make this V0 for sure. Heel hook/calf loop over definitely not necessary.
