Flex Fitness Masterton is a 24-hour, seven-day gym at 219 Queen Street in central Masterton, described by its own team as Masterton's finest training facility. The club brings together group fitness, weight and cardio training, functional gear and expert trainers, with the stated aim of helping members at every level reach their goals.
The floor is fitted with Hammer Strength and Life Fitness equipment alongside functional training gear, and members have ensuite bathrooms and free parking on site. A Tanita body scanner provides accurate body-composition measurements and data, so progress can be tracked properly rather than guessed at.
Coaching is central to the offer: personal trainers help members maximise their workouts, reach goals faster and recover from injury, while a group fitness timetable adds coached sessions to the week. The club also stocks the protein powder, pre-workout and vitamins members need to perform at their best.
Flex Masterton is part of the Flex Fitness New Zealand network and is locally led, with Rach McMahon as Club Owner and Navi Singh as Club Manager. Members can manage bookings and track results through the MyFlex app, and newcomers can grab a free pass to try the club before joining.
Set on Queen Street in central Masterton, Flex Fitness Masterton is a full-scale training facility that never shuts its doors. Open 24 hours a day, seven days a week, the club is part of the Flex Fitness New Zealand network, which spans dozens of locations across the country, but the Masterton club is led locally — Rach McMahon is the Club Owner and Navi Singh is the Club Manager, so the people running the club are the ones members see on the floor each week.
The team describes the club as Masterton's finest training facility, and the fit-out supports the ambition. Members train across dedicated weight and cardio areas, with functional training gear and equipment from two of the best-known names in the industry: Hammer Strength and Life Fitness. Whatever your style — heavy strength work, machine-based training, cardio sessions or functional conditioning — the floor has the tools for it.
That phrase is Flex Masterton's own, and a few details explain it. Ensuite bathrooms mean you can change and freshen up on site, and there is free parking at the club, which takes the friction out of early-morning and late-evening training. Small comforts, but they add up when you are trying to build a habit.
The club also takes measurement seriously. A Tanita body scanner gives members the full picture of their body composition, delivering accurate measurements and data so progress can be tracked properly over time. For anyone working on fat loss, muscle gain or a performance goal, that kind of feedback changes how you train.
There is fuel on hand too: the club stocks the protein powder, pre-workout and vitamins members need to perform at their best.
For members who want individual guidance, expert personal trainers are available. Flex's own framing is that personal training helps you maximise your workout, reach your fitness goals faster, and recover from injury — covering everyone from first-timers who need a plan to experienced lifters refining technique or coming back from a setback. Personal training can be booked and paid for directly through the club's app.
Group fitness rounds out the coaching picture, adding coached, social sessions to the weekly mix. The club publishes a timetable so members can plan their week around the sessions they enjoy, and for anyone who finds a busy gym floor intimidating, a class can be a friendlier way in.
The MyFlex app ties the club together. Available on the Apple App Store and Google Play, it lets members book and pay for personal training, build personal profiles, record biometrics and connect to other fitness apps, and access daily workouts and exclusive promotional offers. Flex's advice is to see the team in your club to find out more and get set up — one more reason the staffed hours matter.
Staffed hours run Monday to Thursday from 10am to 6pm, Friday from 10am to 4pm, and Saturday from 10am to 12pm, with Sundays unstaffed. Outside those windows, 24/7 member access means the club still works around shift work, early birds and night owls alike.
Newcomers do not have to commit blind. Flex offers a free pass through its website, and there is a VIP list for anyone who wants updates from the Masterton club. The team can be reached on 06 370 1911 or at [email protected], and the club sits at 219 Queen Street.
For Masterton locals, the combination is straightforward: serious equipment from Hammer Strength and Life Fitness, coaching through personal training and group fitness, body-composition tracking with the Tanita scanner, supplements on site, free parking, and a gym that is open every hour of every day. Whether you are starting out or chasing a specific goal, Flex Fitness Masterton has the tools — and the people — to help you reach them.
