EUROPEAN
BORN.
THAILAND
BRED.

Kai Voss began training Muay Thai at 18. Within a decade he was competing at the highest level — fighting at Lumpini, Rajadamnern, and eventually winning the Omnoi Stadium title, one of only a handful of Western fighters to do so.

After 6 years living and training in Bangkok at one of Thailand's top 10 ranked gyms, Kai returned to Europe with a singular focus: teaching authentic Muay Thai the way it's done in Thailand — not watered down, not adapted. Real technique, real strategy, real results.

"I don't teach Muay Thai for fitness. I teach it because it's the most intelligent striking art in the world."
