Progressive Fighting Concepts has as its core art Bushido Jiu-Jutsu, as this is what Kevin and Fergus have trained in for over 20 years. Then about 15 years ago when they started discovering gaps in Bushido Jiu-Jutsu as a streetwise form of Self Protection they adopted Bruce Lee’s philosophy of Jeet Kune Do and started training in other martial arts in order to learn how to negate them. It has been developed and pressure tested over the past 15 years by the Joint Chief Instructors Kevin Spargo and Fergus Robertson.
