If it’s a medical emergency, call 111 first. We also have a St John’s alarm at the front desk, so if you need urgent help, head there and activate it and help will be on its way. Please also make sure your emergency contact details in the GymMaster app are kept up to date.

We’re at 121 Main Street, Upper Hutt. The main address is on Main Street, but gym access is from the rear of the building via Leister Lane. Street parking is available directly in front of the gym, and there’s plentiful parking behind the building off Leister Lane too.

If you’re a business interested in talking about our corporate membership rates, please reach out to us at upperhutt@strengthnation.co.nz. Corporate rates are usually available for business that are open to paying by monthly invoice, that have 10+ employees!

Yes, we’ll keep adding classes as our membership grows.

Yes, classes are included with every membership (how many per week depends on your tier).

The weekly timetable is on our website and in the GymMaster app, and you book directly through the app. Classes open for booking exactly one week in advance, so we’d recommend booking as soon as bookings open to secure your spot. Casuals can contact us directly to book. Any questions, just get in touch.

Members book through the GymMaster app (select ‘Book Service’). Casuals should contact the gym directly. Bookings open one week ahead, and we’d recommend booking early, especially for private sessions, as these fill up fast.

Cold plunge access is included with any sauna booking, private or communal, and can’t be booked separately. In the communal sauna, everyone who’s booked that slot shares cold plunge access, so please rotate respectfully so everyone gets a turn.

Yes, for private sauna bookings you’re welcome share your booking with someone, but they must
also be a member, or have a casual pass. Communal sauna seats are booked individually.

Your full session, sauna and cold plunge combined, runs for 30 minutes.

Please shower before your session to keep things clean for everyone, and bring a towel to sit on in the sauna. Appropriate swimwear or clothing must be worn at all times in both the sauna and cold plunge.

Please don’t use the sauna or cold plunge if you’re feeling unwell. If you’re pregnant, or have a heart condition, blood pressure issues, or any other relevant health concern, check with your doctor before booking. We’d also recommend avoiding alcohol beforehand, staying hydrated, and not exceeding the 30-minute session. If you feel unwell during your session, exit straight away and let a staff member know.

You can cancel your booking through the GymMaster app up until 2 hours before your session. If it’s within 2 hours of your session, please contact the gym directly.

Yes, bookings are essential! Book by selecting ‘book a service’ in GymMaster! Bookings are available for a 1 hour slot. If there are multiple children attending, please ensure you let us know in the notes.

Under 3s can’t use the Kids Zone, but they’re welcome to accompany a parent to MumHIIT sessions.

Over 12s are welcome at a parent’s discretion, but priority goes to the 3–12 age group during busy periods.

No, it’s a self-supervised space. Parents and guardians are responsible for checking on their children regularly and for their safety at all times.

No. For health and safety reasons, children aren’t permitted on the gym floor, in studio classes, or in any training area under any circumstances. They need to stay in the Kids Zone for the full duration of your visit.

No shoes are to be worn in the Kids Zone, please remove them before entering. Food in a lunchbox is welcome, but no loose snacks, open containers, or drinks other than water. Sessions are capped at 60 minutes per visit and 10 children at a time, so everyone gets fair access. Soft play, books, puzzles, and our provided toys are all available; please leave outside toys at home.

We ask that children stay in the designated Kids Zone at all times, don’t use gym equipment or wander through the gym, and avoid running or disruptive behaviour. If behaviour becomes disruptive or unsafe for other children, we’ll ask a parent to collect their child, and we reserve the right to ask a member to remove their child from the space if needed. Parents are responsible for any damage caused by their child.

Please make sure children’s hands are clean before play, and hold off bringing them in if they have a cold, cough, runny nose, or other illness, for everyone’s sake. When you collect your child, please clean up any mess left behind (vacuum and cleaning products are provided) so the space stays clean and respectful for the next family.

Yes, as long as you stay inside the facility, your child stays in the Kids Zone, and you’re reachable. You’re still responsible for checking in on them regularly.

Parents must be reachable and within the facility at all times. In an emergency, staff will locate the parent immediately. We take the safety of everyone on-site seriously, but children are brought to the facility at their parent’s own risk, and by bringing a child into the gym you’re accepting full responsibility for their safety and wellbeing.

If it’s a medical emergency, call 111 first. We also have medical alert necklaces, available at the front desk and a St John’s alarm that they are connected to, so if you need urgent help, activate a medical alert necklace and help will be on its way. Please also make sure your emergency contact details in the GymMaster app are kept up to date.

We’re at 121 Main Street, Upper Hutt. The main address is on Main Street, but gym access is from the rear of the building via Lister Lane. Street parking is available directly in front of the gym, and there’s plentiful parking behind the building off Lister Lane too.
