Bushin’s senior team regularly attend seminars taught by the world’s best martial artists to evolve and improve our system

one tool, many uses

Bushin was built with this mantra in mind. Our system thrives on giving you a set of effective tools, taken from some of the most effective martial arts such as Muay Thai, Shorinji Kempo, BJJ, plus others. Then we teach you how to use these tools in many scenarios. We pressure test them with sparring every session so that when you need them, whatever the scenario, you can pull them out without thinking and make them work. Check out our original promo now!

Our Story

Bushin was created in 2009 by Sensei Cailey Barker, following 30 years of martial arts experience. He felt that many traditional styles have great discipline and structure but lacked practicality and the flexibility to adapt. Conversely, modern fighting styles lacked some of the tradition that made learning a martial art special.

Sensei Cailey’s approach was simple. Create the syllabus by drawing from his experience, pressure test it, and adapt it to improve. As a result, Bushin is continually getting better as a fighting system as we discover better and more effective methods and techniques.

No two scenarios are ever exactly the same. How you deal with them should be adaptable as well. To help you, Bushin will give you the tools so you can build your own fighting style, pressure test it by sparring to see if it works, and tweak it if it doesn’t. With us, you can truly build a style personalised to yourself.
