The Girls Who Fight Self Defense & Mixed Martial Arts Program unlocks the hidden super-powers within every girl

So that by the time she reaches her most vulnerable decade of adolescence she's equipped with the confidence, courage, and most incredible fighting skills that will protect and empower her for the rest of her life.


Every parent wants to equip their little girl with effective skills to protect herself. So why are so few girls in martial arts? Because 99.9% of martial arts programs are designed for adult men— not girls. Girls show up eager to learn but they're de-prioritized and too intimidated, self-conscious, and bored to enjoy training, so they quit (and rightly so). This is a tragedy because the people who need effective self defense skills the most, and the confidence that comes with it, are young women.


Girls deserve a top quality martial arts program that's 100% tailored to them. At Girls Who Fight, girls learn relevant self defense skills in the most fun, positive, and confidence-boosting way possible!

Taught By Girls Who Fight Founder & Head Instructor Gemma Sheehan!

Hello, I’m Gemma! I'm a Brazilian Jiu Jitsu brown belt and ex-MMA fighter with 15+ years experience training and competing in kickboxing and Brazilian Jiu Jitsu. I achieved an MMA record of 5-1 and was ranked the best female fighter in Ontario!


In 2017 I retired as a fighter (I was scared of emerging head trauma), but even though I was stepping away from my dream I felt like I could do anything. My martial arts journey gave me immense confidence, significance, physical and mental strength, and conviction that if I worked hard at something I could achieve it.


It’s this life-changing self-belief that girls desperately needed, and gaining super-hero-esque combat skills is a proven avenue to acquire it. It’s such an obvious vehicle for personal growth, so why do so few girls stick to it? Because 99.9% of schools are exclusively focused on adult male competitors, not girls.


Gyms serve the male mass market > girls quit > gyms are re-affirmed they shouldn’t serve girls = almost no girls ever acquire the life-changing benefits of martial arts.

When I left competition, I knew I was the person to change this. I created Girls Who Fight because girls deserve a top quality program 100% dedicated to their needs, growth, and experience. I hope to have the opportunity to share it with you and your daughter one day!

— Gemma
