Strangling with your legs: A strange thing about the system that I teach my students is that the most well known component of it – the strait jacket – was so successful in competition that audiences rarely got to see the other of the system. As a result most people have a rather limited view of the back system as just a series of hand/arm leading to rear naked strangles. In fact, there are four systems designed to assist whenever the main strait jacket system fails. of the most important is the rear triangle – ushiro sankaku- which enables you to use the impressive power of the legs to strangle opponents. This immediately gets you around one the more common problems associated with rear strangles – the difficulty of penetrating under the chin/jaw. The very nature of triangle strangles, using the shoulder to assist the strangle does not require that you get under the jaw to be effective. In addition it offers a multitude of back up attacks if the initial strangle is defended. All of my students excel in this technique as it is a big part of our training. Here, and Craig Jones practice their ushiro sankaku finishes. Their long legs make front triangles one of their favorite techniques- both of them excel at it – but the rear triangle is very effective even for short legged athletes due to more favorable angles and positioning.
