Gracie Jiu-Jitsu (GJJ) is a superior form of self-defense for kids and teens, as it doesn't rely on sheer strength and athletic ability. Instead, it uses leverage and technique over strength and power, making it possible for kids and teens of all sizes and shapes to reach their full potential. This is a fun and exciting way for kids and teens to learn self-defense skills and grow as both martial artists and human-beings.
