Meet Gemma Lu - Founder of Fierce Fitness By GL
Empowering women and children through strength, self-defence, and fierce confidence.

Hi, I'm Gemma Lu - certified Krav Maga instructor and personal trainer, and the heart behind Fierce Fitness by GL. I created this brand to help women feel powerful in their bodies, confident in their lives, and capable of defending themselves.
My journey began with a passion for movement and turned into a mission: to create a space where women could train hard , feel safe, and push past limits they never thought they could.
Through strength training, resistance-based programmes, and real-world-self-defence techniques, I help clients build not just muscle, but a healthy, unwavering mindset.
The individuals who train with me are all courageous and powerful. We support one another and take our workouts at our own pace, creating a healthy and enjoyable environment where we leave each session with bigger smiles than when we arrived—myself included! I am an inclusive trainer, working with people from diverse backgrounds, neurodivergent individuals, and all sexual orientations.
I look forward to the opportunity to teach and support more empowered individuals, helping them feel safer and more powerful in the world!
