Learn moreWelcome to Big Monkey Muay Thai — where every punch tells a story. This isn't just a gym. It's a haven for dreamers and a battleground for champions in the making.
For founder Tim Wicks, a childhood dream became a lifelong commitment. Tim mastered Muay Thai not just as a sport but as a tool for positive transformation — and built this gym so that everyone who walks through the doors gets the same chance.
A childhood dream turned lifelong commitment. Every session at BMMT is fuelled by the same dedication that built the gym.
Greatness here is about shaping character, fostering discipline, and instilling empowerment in every individual.
We build more than fighters — resilient minds, strong bodies and unwavering spirit. Every challenge faced is a step forward.
