Physical Self Defense
At Girls Who Fight, we teach a complete system of self-defense designed for girls and women. Our training blends the most effective techniques from Jiu Jitsu and Muay Thai to give you the skills, mindset, and confidence to handle real-world threats.
Self-Defense Jiu Jitsu
Escape grabs, chokes, headlocks, and ground pins, and learn how to use leverage, joint locks, and submissions to overcome larger attackers. We focus on practical self-defense, not sport.
Muay Thai Kickboxing
Build striking power with punches, kicks, knees, and elbows while mastering defense, footwork, and timing. You’ll gain the speed, strength, and control to protect yourself and stay one step ahead.



We Help Girls Build the Character and Habits
That Lead to Confidence, Health, and Success
The Girls Who Fight Self Defense Program® empowers girls ages 7–16 with real-world self-defense skills—physical, mental, and verbal—that protect and strengthen her for life.
Not only will your daughter learn how to defend herself, she'll gain the knowledge to never become a target, the positive habits that foster health and happiness, and the strength of character to live a confident, successful life.

Meet Your Instructor
Jiu Jitsu Black Belt • MMA Champion • Girls Who Fight Founder
Coach Gemma Sheehan, a former MMA fighter and champion, earned her Jiu Jitsu Black Belt from 12-Time World Champion Rafael Barbosa, and spent years training under World Kickboxing Champion “Bazooka” Joe Valtellini. She has won Pan American Championships in Jiu Jitsu, and was ranked as the #1 Female MMA Fighter in Ontario, with a record of 5 wins 1 loss. Her competitive background brings together the worlds of Jiu Jitsu and striking, but her true passion and teaching expertise is in applying martial arts for Women’s Self Defense.
"In 2017, I retired from competition. Walking away from my dream wasn’t easy—but I left with something even more powerful: the belief that I could do anything. Martial arts didn’t just give me the ability to win fights in the octagon, it gave me something far more valuable: the unshakable belief that I could do anything.
Confidence, strength, grit, mental and physical toughness, patience, focus, self-discipline– it gave me the MINDSET of a champion. A mindset I could apply to anything I wanted.
This made me wonder: there’s a martial arts gym on every corner, so why aren’t more women and girls experiencing this transformation?
The answer was clear—most martial arts schools are built for men who want to win fights, not for girls who want to protect themselves and gain all the qualities of a strong character.
That’s why I created Girls Who Fight. Since 2017, I’ve been building a program that would revolutionize self defense for women and girls. We stripped the elements that hold girls back, and narrowed in on the most valuable, priceless, life-changing benefits of a martial arts education:
-
The physical skills to defend your life.
-
The knowledge to avoid violence.
-
The confidence and character that propels you to health, happiness and success in every endeavor.
The Girls Who Fight Black Belt represents excellence in all three areas. It is the only program of its kind, and I am honored to share it with your family."
