Jiu Jitsu

With deep roots in late feudal Japan, Jujutsu (traditional spelling) spread its roots to Brazil during the beginning of the industrial revolution. Japanese businessmen visiting the area such as the legendary Mitsuyo Maeda began teaching "street judo" the locals who were interested in the Japanese culture. Over the last hundred years, the Brazilian blend of Jiu Jitsu has since spread to the four corners of the globe as the most advanced, conceptual fighting art known to man. Built for the smaller person to utilize technique and timing, Jiu Jitsu is the #1 martial art world wide to overcome a larger, stronger single aggressor.

Thai Box

Reaching back to ancient Siam, Muay Thai was developed to protect their capital city and later became the preferred hand-to-hand combat strategy of the nations military. Spanning hundreds of years, the "art of the eight limbs" has become a world renowned striking fight-sport and the national past time of Thailand. Its well-balanced and overwhelming striking style utilizes powerful kicks, knees, elbows and punches along with strategic clinching. Thai Boxing is now the preferred striking accompaniment to Jiu Jitsu by mixed martial artists worldwide.
