Kamau trains and instructs jujitsu with an emphasis on self defense, utilizing sport and traditional techniques as well as techniques derived from wrestling, judo and MMA. He strongly believes jujitsu is a game of human chess, utilizing technique and problem solving skills over strength and agility. The study of jujitsu teaches humility while instilling confidence, gets one in amazing shape while learning to not rely on physical attributes and it teaches how to win by understanding your losses. The smallest opponent can defeat the biggest by using angles and manipulating leverage, making it as much a thinking game as a physical sport.
