Flex Fitness Newmarket is a 24-hour, seven-day gym on Calton Gore Road in the heart of Newmarket, Auckland — a club built around the motto that 'your gains are our gains.' Members get round-the-clock access to a floor kitted out with Hammer Strength and Life Fitness equipment, along with ensuite bathrooms for showering and changing on-site.
The club goes beyond the weights and machines. Expert personal trainers help members maximise their workouts, reach goals faster and recover from injury, and a group fitness timetable adds the energy of training alongside others. A smoothie bar sits inside the gym serving a variety of healthy options to refuel after a session, with supplements also available in-club.
Progress tracking is a real focus here: a body composition scanner gives accurate measurements so you can see the full picture of your body, while the MyFlex app lets members book and pay for personal training, record biometrics and connect to other fitness apps. The club is staffed Monday to Thursday 10am–7pm and Friday 10am–4pm, with member access continuing outside those hours, and free trial passes are available for anyone keen to try Flex today.
Flex Fitness Newmarket sits on Calton Gore Road in the heart of Newmarket, and its pitch is simple: the gym where your gains are our gains. This is a 24-hour, seven-day club, so whether you train before dawn, after a late shift or straight through the weekend, the doors are open for members whenever you are ready to work. And the club's message to newcomers is just as direct — everyone's reason for change looks different, and its job is to help with yours.
Most gyms ask you to fit your life around their hours. Flex Newmarket flips that. Members have round-the-clock access to the club, while the team is on hand during staffed hours — Monday to Thursday from 10am to 7pm and Friday from 10am to 4pm. Weekends run unstaffed, but member access continues, which makes the club a practical option for shift workers, early birds and anyone whose schedule doesn't fit a nine-to-five. If you're new, it's worth timing your first visit for a staffed hour so the team can show you around, talk through memberships and get you set up.
The gym floor is equipped with Hammer Strength and Life Fitness equipment — two of the most recognised names in gym hardware. That means plate-loaded strength stations for lifters and a full spread of cardio and resistance machines for everyone else, whether you're chasing your first pull-up or your next personal best. Ensuite bathrooms mean you can shower and change on-site and head straight to work or home afterwards.
Coaching is a big part of the offer. Flex Newmarket's personal trainers work with members to maximise workouts, reach fitness goals faster and recover from injury under expert guidance. Recovery is part of the picture too — trainers can help you come back from injury with a structured plan rather than leaving you to figure it out alone. Sessions can be booked and paid for directly through the club's MyFlex app, so planning your training week takes seconds. There's a group fitness programme as well, with a timetable of classes for members who like the energy of a full room; check with the team for the current schedule.
One thing you won't find in every gym is a smoothie bar — Flex Newmarket has one inside the club, serving a variety of healthy options to help you refresh and refuel after a workout. Supplements are also available in-club if you want to back up your training with the right support.
Progress here isn't left to guesswork. The club runs a body composition scanner that gives you the full picture of what's happening under the skin — accurate measurements and data you can track over time. Scans can be booked online, and members can record their biometrics in the MyFlex app and connect it to other fitness apps they already use. The app is also the place to find daily workouts and exclusive promotional offers once you're a member.
Flex Newmarket is led by Club Manager Louie Chung and his team, and it's part of the wider Flex Fitness New Zealand network, which spans dozens of clubs from Auckland to Queenstown. That scale shows up in the details — the app, the booking systems, the equipment — but the atmosphere is local, and the club describes itself as more than just a gym: it's a lifestyle.
If you're curious, the easiest way in is a free trial pass, available from the Flex Fitness website. You can even take a virtual tour of the club online before you visit. Once you're ready, you'll find Flex Newmarket at 96b Calton Gore Road — reachable on 09 522 4522 or at newmarket@flexfitnessgym.co.nz — ready whenever you are.
