Dimitri Chrisos Jiu Jitsu Academy offers group and private instruction in Brazilian Jiu Jitsu, the most complete ground fighting system and one of the fastest-growing martial arts in the world. BJJ focuses on grappling or ground fighting. It is based on the principle that a smaller and weaker person will be more likely to survive against a bigger, stronger assailant by “taking the fight” to the ground and using techniques based on leverage and body mechanics (e.g., joint locks and choke holds) to defeat the attacker. In its self defense application, BJJ emphasizes survival first and defeating the opponent (by submission) second. Because it is based on grappling techniques via leverage, rather than striking and an over reliance on speed and body strength, BJJ is an ideal martial art for both women and men of all ages regardless of their physical size or athletic abilities.
