Every gym has a story. Ours starts back in 2012, in a suburb called Alderley on Brisbane’s Northside. This is where City 4051 CrossFit first opened its doors.
Where It All Began
When we opened in Alderley in 2012, the owner Jimmy had already been coaching CrossFit for 3 years. Having learned from some of the top CrossFit coaches in the country, Jimmy developed a strong in the methodology, a passion for coaching, and a small but dedicated community of members who trained hard and looked out for each other.
That community grew. Members referred friends, partners started training together, and before long, City 4051 had become something we were incredibly proud of — not just a gym, but a genuine community.

The Move to Chermside West
In 2020, we made the move to Chermside West. A larger space, better facilities, more equipment — and the same team and community that had been built over eight years in Alderley.
The name stayed the same. 4051 is Alderley’s postcode, and it’s where this all started. Keeping it felt right — a nod to our roots, and a reminder of what this gym was built on.
What We’ve Learned in 14 Years
After more than a decade of coaching, we’ve learned a few things that shape everything we do. The most important: people don’t stick with training because they have iron willpower. They stick with it because they enjoy it, because they feel part of something, and because they see real results.
Functional group training elicits far more benefits than just physical fitness. This style of training can be a great stress relief and helps improve mental health and wellbeing. It’s also a great way to form social connections and build lifelong habits that are great for long-term health.
That’s why our coaching philosophy puts the experience front and centre. Class workouts are programmed to be challenging and rewarding for everyone — whether you’re a beginner scaling your first workout or a competitive athlete chasing a personal best. The environment is supportive without being soft. And the results speak for themselves.

The Best Gym Community on Brisbane’s Northside.
Today, City 4051 is home to students, parents, grandparents, shift workers, couples, and competitive athletes. They’re all here for different reasons, and they all stay for similar ones: great coaching, genuine community, and training that works.
