Keystone Martial Arts (Baulkham Hills)

Keystone has strong links to both traditional & contemporary martial arts. At Keystone we teach the Northstar Jujitsu (NJJ) system of Martial Arts which is a powerful, easy to learn self-defence system suitable for men & women of all ages and children from 5 years of age.

NJJ combines elements from various martial arts including Taekwondo, Jujitsu, kickboxing, Judo and Aikido into a blended system that gives students the advantage they need to protect themselves in virtually any situation.
