Brazilian Jiu Jitsu (BJJ) is a martial art, combat sport and self defense system that is one of the most popular and fastest growing activities today. BJJ is an art form that emphasizes ground fighting techniques which involve various chokes and joint locks used to dominate and submit the attacker.

Princeton Brazilian Jiu Jitsu provides expert instruction in the Princeton, New Jersey area in both gi and no gi grappling. Taught by two renowned instructors, Arthur Keintz and Emily Kwok, students can expect classes that will include a dynamic warm up, technique and live sparring. This program will expose the student to both the self defense and competitive aspects of the sport. Must be 14 or older to register, beginner and advanced practitioners are welcome.

You can't teach someone to read and tell them not to read other books ... so why would you do that to jiu jitsu?  —Art Keintz

JDK/Muay Thai

JKD, or Jeet Kune Do is a hybrid martial art that was created and introduced to the world by the legendary, Bruce Lee. The art covers the 4 ranges of combat: kicking, punching trapping, and grappling, which ideally build the framework for a student to develop a 'personal system' of self defense. 
Class time is also spent learning one of the most effective combat systems from Thailand, 'Muay Thai', or the art of eight limbs. You will continue to explore how to effectively strike using fists, elbows, shins, knees and feet, while developing their physical and mental discipline.
