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'.
