What We Teach

Our martial arts school teaches Dutch-style K1 Kickboxing and Boxing, with elements from Western & Soviet Boxing styles, Muay Thai, Karate and Taekwondo. We focus mainly on K-1 Kickboxing and Amateur Boxing, but we also practice and compete in Full-contact Kickboxing and Continuous Tatami Disciplines.

Coached by Champions

Our coaching team blends Multi-time British Champions and battle-tested instructors who’ve cornered and competed in hundreds of bouts. Whether you’re chasing a world podium or lacing up for the first time, you’ll learn from coaches who’ve fought, won, and coached fighters to victory—in both K1 Kickboxing and Amateur Boxing.
