About

At CrossFit TwentyThree, we believe that great coaching builds fitness, but great people build community. Every workout is an opportunity to challenge yourself, support those around you and become part of something bigger than a gym. Whether you’re stepping into CrossFit for the very first time or chasing your next competition, you’ll find expert coaching, genuine friendships and a community that’s invested in your success; both inside and outside the gym.

OUR SPACE

More than just a gym, our purpose-built facility gives you the space to train, recover and connect. Dedicated training areas, luxury changing rooms, flexible open gym access and welcoming community spaces all come together to create an environment where you’ll genuinely enjoy spending your time.

The Box

Our main CrossFit and HYROX class floor, built for high-energy classes, big lifts and serious conditioning, with space to move, breathe and perform at your best.

The Workshop

A dedicated open-gym and performance space where you can train your way, whether that’s extra strength work, skill practice or your own programming.

Changing Facilities

Spacious, modern changing rooms with premium showers and vanities, so you can go from training to the rest of your day feeling fresh and ready.

Members’ Lounge & Co-Working

A relaxed mezzanine space to recover, work or socialise. Perfect for coffee, laptops, and catching up with the community after a session.

Meet the Coaches

At CrossFit TwentyThree, our coaches are more than just great trainers, they’re educators, mentors and teammates. We coach with purpose, using simple and smart programming, clear instruction and genuine care to help every member move better, train harder and keep making progress, whatever their starting point.
