What We Do


Brazilian Jiu-Jitsu

BJJ is a martial arts/combat sport that focuses on grappling and especially ground fighting. It teaches that a smaller, weaker person can successfully defend against a bigger, stronger assailant by using leverage and proper technique.


Submission Grappling

Submission Grappling is a general term describing the aspect of combat sports that focuses on ground fighting with the aim of obtaining a submission using submission holds. This refers to competition and training that does not use a 'jacket' or 'gi'.


Mixed Martial Arts

MMA is a full contact combat sport that allows the use of striking and grappling techniques, both standing and on the ground, including boxing, wrestling, BJJ, Muay Thai, and other styles.
