Allie HawthorneJuly 2026

The gym space that Dayna has created is a very welcoming environment. The coaches give you guidance and encouragement throughout the class and the people and community make you want to show up. If you want to try a functional training space and are anxious, this is where you want to start.

Shania MitchellJuly 2026

I can’t recommend Within Lifestyle and Fitness Centre highly enough. From day one, I was made to feel genuinely welcome by every member of the team. The staff are friendly, encouraging, and always take the time to say hello, making it feel like so much more than just a gym. The functional training classes are one of the best things about Within. Every workout can be adapted to suit your individual fitness level, so whether you’re stepping into a gym for the first time or have been training for years, you’ll feel supported, challenged, and included. The centre is always spotless, creating an environment that’s enjoyable to train and recover in. I also love how simple and convenient it is to book recovery sessions through their system—it makes prioritising recovery effortless. What really sets Within apart is the community they’ve built. It’s a place where you feel encouraged to become the best version of yourself, surrounded by coaches and members who genuinely want to see you succeed. I’m so grateful to have found this gym and wouldn’t hesitate to recommend it to anyone looking for a welcoming, supportive place to train.

Madeline DimmockJuly 2026

WITHIN has been a game changer for me!!. Amazing community, everyone is welcomed and celebrated no matter where you are at or who you are. With the most epic workouts, I’m never bored and my skills have improved significantly in a shorter period of time than they ever in the past. I recommend WITHIN to everyone 🫶🏼

Chelsea BoothJuly 2026

After being away from the gym for 18 months returning to Within felt like coming home. The community is unreal and the coaches are amazing!

Samuel BoothJuly 2026

Great community & Gym

Elli LeonardJuly 2026

This gym has genuinely changed my life, both mentally and physically. Every single day I'm challenged to become a stronger, healthier version of myself, and I leave feeling proud of what I've achieved. The coaches are incredibly knowledgeable, supportive, and motivating. They know exactly how to push you beyond what you think you're capable of while making you feel encouraged every step of the way. The community is just as amazing, everyone is welcoming, uplifting, and always ready with a smile or a laugh. If you're looking for a place that will challenge you, improve your health, boost your confidence, and make you actually enjoy working out, this is it. And a special shout-out to Dayna, you're an absolute superstar! Your encouragement, energy, and genuine care for every member make such a difference. Five stars simply aren't enough! ⭐⭐⭐⭐⭐

tyla AddertonJuly 2026

Unreal place to workout! Great for mums, such a lovely community Dayna and all the coaches are awesome both Pilates and functional :)

angie jancJuly 2026

I’ve been training at Within Lifestyle and Fitness Centre for since it opened, and being part this gym has been one of the best investments I’ve ever made in my health and wellbeing. I’ve become stronger, fitter, and more confident than I ever thought possible. As I’ve gotten older, staying active has become even more important to me, and the coaches have always been there to support, encourage, and challenge me in a way that feels safe, achievable, and rewarding. The programming is fantastic—every workout is different, challenging, and can be adapted to suit every ability. Whether you’re completely new to functional fitness or have years of experience, you’ll never feel out of place. What keeps me coming back, though, is the people. The community at Within is unlike any other gym I’ve experienced. Everyone is welcoming, encouraging, and genuinely happy to see each other succeed. It’s a place where you feel supported on the hard days, celebrated on the good days, and motivated every step of the way. Within Lifestyle and Fitness Centre is so much more than a gym—it’s a community that has had a positive impact on my life, and I’m incredibly grateful to be part of it. I wouldn’t hesitate to recommend it to anyone, regardless of age or fitness level. Love this place 🥰

Nicky MaudeFebruary 2026

Great workouts, with fantastic instructors who always change it up and make it work for everyone. Highly recommend giving it a go.

Ryan AllanFebruary 2026

The best.

Koda MatthewsFebruary 2026

Pilates at Within Lifestyle and Fitness Centre has been such a positive experience for me. The sessions cater to every ability level and are thoughtfully adapted for anyone managing injuries, so you always feel safe and capable. The instructors are experienced, encouraging and very mindful. They focus on proper form and individual support, helping you build strength and confidence at your own pace. The atmosphere is friendly and uplifting, making it easy to feel comfortable from your very first class. I couldn’t recommend Pilates more highly.

Casey WilliamsFebruary 2026

Pilates at Within is the best thing I’ve done for myself in a long time. Great for any level and accomodating of injuries. All the instructors make you feel welcome and supported and I highly recommend you give it a go.

Rachelle MorrisseyFebruary 2026

I started with the 10 day trial pass to see how I felt after taking a year away from training and trying to find something I could do while recovering from an ankle injury. Pilates turned out to be exactly what I was looking for! I have felt so welcomed and supported since joining. The timetable is also incredible! So many options for busy schedules! I’m so glad I finally joined and wish I didn’t put it off for so long!

Emma TaconFebruary 2026

I love within! As a plus sized woman and mum, within makes me feel so comfortable to train there and the trainers make the feel safe and informed to give anything a go. My health and fitness has improved massively since joining, and love the options of the ice bath and sauna for recovery, even as a once off every now and then.

PhoebeFebruary 2026

Within is the best gym I have ever been too! The gym that has it all - weight training, mat pilates AND a recovery area (sauna/icebath). Could not recommend this gym enough, definitely give them a go!

jas cuznerFebruary 2026

I recently moved to the area and this gym has been so welcoming. Dayna and all of the coaches are friendly and supportive, and the community is great. I love the programs, especially the mix of functional training and Pilates. Such a positive place to train

Kerrie EvansFebruary 2026

What I’ve loved most about Pilates at WITHIN is the welcoming vibe and the genuinely supportive instructors. Every class leaves me feeling stronger, more grounded, and so connected to my body. I always walk out feeling strong, calm, aligned, energised and clear — and that feeling lasts well beyond the mat.

Jacinta BamblettJanuary 2026

Hands down the best gym I've ever been part of. I can't recommend this gym highly enough. They offer functional fitness (CrossFit-style, but honestly better) as well as Pilates classes, so there truly is something for everyone. No matter your age, size, shape, or fitness level, even if you have zero fitness background, the coaches and programs meet you exactly where you're at. The coaching is outstanding - knowledgeable, supportive, and genuinely invested in helping you progress safely and confidently. On top of that, the community is incredibly warm and welcoming. From day one, you feel supported rather than intimidated. If you're looking for a gym that delivers great programming, amazing coaches, and an inclusive, positive environment, this is the place.

Linda CroftsJanuary 2026

A supportive and inclusive gym, where everyone feels welcome. The trainers are all amazing and very knowledgeable. From functional fitness, and mat pilates to recovery there is something for everyone.

janet shortJanuary 2026

A great gym. The classes are challenging but made fun and suitable for every one at their own level. I love it and wouldn't recommend that you go anywhere else.

Amie TamplinJanuary 2026

Such an amazing community and vibe. I love having alternative options to suit where I am at in with my fitness level and the support from everyone around

Tegan HodgesJanuary 2026

Such a welcoming gym and community. Every time I go and complete my workout I’m greeted so warmly by all the staff and the members, it makes returning for the next session so easy. The Pilates classes are so much fun and I feel like I get a lot out of each class. The ice bath in the recovery section is a nice treat and I didn’t realise how much more focused and relaxed I am afterwards!

ellie kokozakiJanuary 2026

The most welcoming space, everyone is so friendly. Absolutely love the Matt Pilates classes.

Journey to Postpartum Birth & Postpartum DoulaJanuary 2026

10/10 would recommend Within! Incredible community, with intentional training that can be made accessible to anyone from just starting out, to injured, pregnant or in their golden years. Within will get you fit, help you get strong and give you the space to do what you never thought you could in your training
