what our clients are saying

  • Malama

    Definitely hands down one of the best gym communities to be apart of. I first began in their semi-private classes & learned 10/10 techniques on how to do proper weight lifting training. I have now been able to transfer that onto a new exciting sport & receiving 1 on 1 coaching from one of their Coaches. They are so big on technique over anything else & 7 months of being a member there, I totally understand why they're so passionate about getting techniques right to avoid any possible injuries. When you get the technique right, the results show up so much faster than you believe. This is the longest my results have been consistent! They don't do challenges, they do lifestyle changes. Super grateful for these guys, highly recommend! I travel from Massey to Browns Bay because of the value they share 👌

    Had my first session with Wiremu today after being off for a long time having my two beautiful babies! I was told he was a stickler for form and would be able to adjust the session to support a postpartum body, and was not disappointed. Really looking forward building my stregnth back with the team’s support - highly recommend. Massive mumma bonus: there’s specific mum lifting classes AND a room with toys and a change table for the kiddies while you train!

  • Mia

    When I first started at NZironStrength, I wasn’t sure what I was doing trialing another gym. But from here on out and currently I’ve learned so much more with exercising, correcting my form and techniques. I get so much patience, knowledge and quality sessions every time! I feel the gains the next day too and you are well looked after too! Worth the prices!🙌

    I used to avoid any machines and not know how to use them. I was so used to doing group classes but one of my goals were to learn how to use the gym equipment. So far, I now know the use of weight machines and the benefits of most machines. 🙌

    NZ Iron Strength is a safe space, a warm friendly family space for all levels and for all ages too😍 Starting from teens. They also offer nutrition plans, good music, showers, and a certified masseuse 😍🔥

    If you’re looking at joining, seriously come through! You’re missing out! You won’t regret it 😊

    Wiremu is an awesome guy. He is a great role model to my boy, and is teaching him the right way to lift, to avoid injuries. I’d suggest starting training here with one-on-one for that very reason. 5/5

  • rae

    Where to start with this place 😍 Wiremu is an absolute legend!! His knowledge, experience and overall manner and vibe is amazing!!

    The space is clean, tidy and a cool spot to be in, the overall feel and energy of the place is something else!! Positive and motivating!!

    Shani promptly sent my meal plan and I’m looking forward to getting a massage in the next few weeks from her.

    Check this place out, you won’t be disappointed.

    Ample carparks, showers and toilets to use and a personal feel to the whole gym.

    Great pricing too!

  • James

    Awesome gym! Wiremu and Shani know their stuff. Good layout and great equipment. Wiremu as a coach was the best thing that happened to my strength training, taught me the fundamentals and helped fixed my form on the key lifts, squat, bench and deadlift. My numbers sky rocketed after that, highly recommend no matter what your fitness goal is!

  • Ricky

    This is the gym to go to, owner and trainers are super friendly and will answer any question you have. Been going here for a couple months now and if you wanna see growth and achieve your goals this is the place to be. Wicked gym all around 👌

  • Bianca

    I don’t say this lightly, but this is honestly the absolute best gym I had ever been too! I left as my family and I relocated to Brisbane, and I have desperately been searching for a gym that even comes close to this gym.

    I had NEVER been taught how to breathe properly (which makes all the difference BTW), I had never had my form watched so closely and corrected, let alone been encouraged to go up in weights like I did, safely.

    Honestly, at this gym, you are not just a number and walking $$$ signs, you’re seen as an individual, human and treated with the utmost respect.

    I learnt so much at this gym, it made me feel confident, not to mention the strength I felt.

    I would highly recommend this gym to absolutely everyone if you want amazing results & to be a part of an incredible environment.

    It’s a small, family owned gym, which makes it ever that more special.

  • Vicki

    I can't rate this gym highly enough. The most supportive and inclusive culture I've ever experienced. Within a month I've noticed a huge difference in my physical well being , strength and body shape. The coaches are passionate, dedicated and extremely motivated to ensure you are being the best you can. I'm hooked.

  • Dennis

    Wiremu is the best trainer I have ever met. He have taken me to the next level! I am thrilled with the varied routines he have developed for me. Keep me interested and motivated, and I love the improvement in my body. I look forward to reaching new heights together. Thank you for taking me on this journey.goes here

  • Eric

    10/10 gym. The owner is great, constantly giving amazing tips and tricks. He knows his stuff, and the equipment is great and an overall great environment to gym in.

  • Thomas

    I have been going to this gym for over a year now and feel very welcomed when ever I come in. The equipment is great and the machines feel like they are giving me the best activation possible. Everyone here is very nice, from the workers to the people here and recommend to any gym goers of all ages.
