Female Self-Defence
We are committed to creating a safe and empowering space for women and girls to learn effective, practical self-defence through BJJ. Brazilian Jiu-Jitsu is uniquely suited for real-world scenarios, focusing on leverage, positioning, and control – allowing a smaller person to defend themselves against a larger opponent.
Whether you’re interested in self-defence, fitness, or just trying something new, you’ll find strong support, expert instruction, and a positive community here. We welcome women of all ages and experience levels to join our regular adult classes – no prior martial arts background needed. Contact us about booking your free trial!
