CTX is a program created by Sensei Luis Costa and Sensei Salvatore Tranchina, which main base is Cuong Nhu, which is a very complete style, but it incorporates modern tendencies and other styles, that in our vision, not only makes the based style stronger, but it also brings it to a new modern era in training high level athletes. Cuong Nhu was founded in 1965 by Grandmaster Ngo Dong. Cuong Nhu Oriental Martial Arts Association is a federally recognized non-profit educational organization. Cuong Nhu is a martial art that blends the basic elements of a number of different styles. Cuong Nhu has its roots in Shotokan Karate and combines aspects of Aikido, Judo, Wing Chun, Vovinam, Tai Chi Chuan, and Boxing. It is this blending of hard and soft styles from which Cuong Nhu (pronounced Kung New) derives its name, which is Vietnamese for Hard (Cuong) - Soft (Nhu).
