Kenshikiryu Jujitsu This class consists of takedowns, throws, pull-downs, and many ways to take an opponent to the ground. It only teaches how to keep them there by striking, choking, joint manipulation and locks, pain points, and finishing holds. Much of this art is modeled after the popular mixed martial arts fighting. This is combative martial wrestling to submission. Jujitsu class is supervised by Kyoshi Gravelin. He has been on the mats for over 25 years and holds a brown belt in Aikido, Judo, and two different styles of Jujitsu -- including a 3rd degree black belt in Kenshikiryu.
