Fight to Find
Yourself.
Our mission is to empower women through combat sports, building a global community that redefines strength, in body, mind, and purpose.
How It Started
Our Story
What began as a single class in London quickly turned into something bigger, a vibrant community of women from all walks of life who wanted to train hard, be themselves, and connect in meaningful ways.
Founded by Kaz Crossley and supported by a powerhouse team of coaches and creatives, Combat Collective was built on the belief that combat sports can be more inclusive, more empowering, and more transformative.
Since then, we’ve hosted sold-out retreats in Thailand, run dozens of run workshops across the UK, and built a global sisterhood that continues to grow.

Our Mission
Built With Purpose
At Combat Collective, we believe every woman deserves a space where she can train hard, take up space, and feel truly seen.
Muay Thai and combat sports are our tools, but transformation is our goal. Whether you’re learning your first jab or finding your rhythm again after a break, we’re here to help you reconnect with your strength.
We’re not only teaching technique, we’re building resilience, community, and confidence that carries far beyond the gym. Together, we’re challenging norms and creating something better.

The Collective in Action
We believe strength doesn’t stop at the mat. From supporting gym builds in Thailand to fundraising for Little Lady Locks, we’re committed to creating impact that goes far beyond our classes and retreats.
We’ve helped underrepresented communities find purpose through Muay Thai, partnered with grassroots initiatives, and made giving back a key part of what we do. Because real strength uplifts others.
