Hyperbolic Fitness is a Christchurch gym on Battersea Street in Sydenham, built for people who want to train hard in a space with genuine character. The gym is filled with high-quality equipment and great training spaces, all branded with iconic murals designed to inspire you to be the best version of your gym-self. It is, in their words, your ideal training environment — a place where you can feel yourself getting stronger in no time.
The current chapter began in 2022, when owner Nick — who brings over 12 years of gym experience — bought what was already an iconic Christchurch gym. The brilliant trainers, incredible members and results-driven fitness classes stayed; the equipment got polished up, and a love of limit-breaking training was worked into the interior design. The vibe is proudly anime-fuelled, summed up by Nick's answer when asked how excited he was for others to experience the place: "OVER 9000!"
Training here is flexible and inclusive. A diverse range of classes is updated on a regular basis by experienced instructors and caters for a wide range of fitness abilities, while membership options suit everyone from visitors in town for a day to locals after a longer-term commitment. Hyperbolic Fitness also runs a second Christchurch location in Islington, sharing the same people-first ethos: an inclusive gym, here to level up the Christchurch fitness world.
Tucked into Battersea Street in Sydenham, Hyperbolic Fitness is a Christchurch gym that wears its personality on its walls — literally. Iconic murals brand the training spaces, the team drops Dragon Ball Z references without a hint of irony, and the whole operation runs on one belief: time is irrelevant when it comes to meeting your gym goals. Whether you have years of training behind you or you're stepping onto a gym floor for the first time, the invitation is the same. Come along for a visit, train hard, and go super saiyan.
Inspired by a range of international training regimes, the team's mission is to level up the Christchurch fitness world. The gym's current chapter began in 2022, when owner Nick — a coach with over 12 years of gym experience — took the opportunity to buy what was already an iconic Christchurch gym. Rather than start from scratch, the new ownership kept what worked. The brilliant trainers stayed. The incredible members stayed. The results-driven fitness classes stayed on the timetable. What changed was the polish: high-quality equipment was spruced up, and the team's love of limit-breaking training was baked into the interior design, creating the mural-covered training environment members see today.
Asked how excited he was for others to experience the unique training environment, Nick's answer was as on-brand as it gets: "OVER 9000!"
Inside, the gym is filled with high-quality equipment and great training spaces, giving members room to chase strength, conditioning and general fitness without fighting over a single rack. Between the gear and the layout, it's pitched as your ideal training environment — somewhere you can feel yourself getting stronger in no time. The murals aren't just decoration, either: they're part of the gym's ethos of inspiring you to be the best version of your gym-self every time you walk in.
Classes are a core part of the Hyperbolic offer. The instructors keep a diverse range of classes on the schedule and update them on a regular basis, and every session caters for a wide range of fitness abilities. That makes the floor genuinely inclusive: first-timers, returning exercisers and seasoned lifters can all find a class that meets them where they are, pushed along by trainers who know what they're doing.
Membership is built around flexibility. If you're in town for a day — a visitor to Christchurch, perhaps, or someone whose routine changes week to week — there's a short-term option to get you training. If you're settling in for the long haul, longer-term memberships give you a home base. Sign-up happens online through the club's membership portal, so you can sort out your membership before you even arrive.
Hyperbolic Fitness actually runs from two Christchurch sites. Alongside the Sydenham gym on Battersea Street, there's a second location at 670 Main South Road in Islington, each with its own sign-up portal and phone line — so if Battersea Street is your gym, you'll want the Sydenham contact details: 020 407 95107 or [email protected]. The friendly staff tend to reply to all enquiries within 24 hours.
What ties it all together is the people-first ethos. Hyperbolic describes itself as an inclusive, Christchurch-first gym where the goal is to level up the local fitness world, and everything from the class programming to the artwork is geared toward that. It's a gym that takes training seriously without taking itself too seriously — the kind of place where getting stronger and having a laugh aren't competing priorities.
If you're after a training environment with real character — high-quality gear, regularly refreshed classes, flexible memberships and a community that backs your progress — the Sydenham gym is worth a visit. Time might be irrelevant to your goals, but a gym this welcoming makes showing up a lot easier.
