It's not really surprising that the Cross Armbreaker actually hurts, given that it's a legitimate martial arts hold that's been used for centuries. But hurt, it definitely does. In fact, it hurts a lot. The Cross Armbreaker is more commonly known as a straight armbar, and originated as a Kodokan Judo technique. Since then, it's been incorporated into Brazilian Jiu-Jitsu, Sambo, Jujutsu and catch wrestling. It's also one of the most common submissions in MMA matches, and is a particular favourite of Ronda Rousey's. It even crosses over into video games. The variation used by Del Rio involves crossing your leg over the opponent's arm and flipping them into the hold, which I first saw done by Paul Phoenix in the Tekken series.How the move works is by fully extending your opponent's arm between your thighs, with your legs across his chest and holding his wrist against your chest with his palm facing up. From there, all you have to do is hold on tight to their wrist and lean back, arching your hips forward. This will hyperextend their elbow joint, causing massive amounts of pain and possibly breaking their arm. When the hold is locked in fully in a real martial arts fight, it's nigh impossible to escape from. Unless you tap out. Which you should. Very, very quickly.
