WHAT OUR MEMBERS SAY ABOUT US

I love F45OTH ❤️ it’s not just about working out, it’s a community that uplifts, supports you, and cheers you on! They not only provide a space to help you achieve healthy lifestyle goals for your body, but for my mental health as well. I hope every gym has these same values. Oh and the trainers train push me in class by doing reps with me. Has been the best, continuous support I’ve ever had at a gym 😁

Completed a trial and promotional week here at F45OTH and have decided to sign up! The trainers are excellent, so welcoming, friendly and knowledgeable. The space is massive and always well maintained. It’s motivating to be a part of a like-minded community and everyone goes hard. The classes help to build strength and tone, as well as working on stabilising muscles. Get involved.

Such an awesome culture where everyone is welcome. I’ve been off on maternity leave and come back to F45OTH to get back in shape. Not only the body, but more importantly the mindset and healthy habits. Loved the encouragement during December to just turn up that’s all I needed to motivate me whilst having weeks of events! Highly recommend.

I’ve joined several gyms before & it didn’t last long, whereas F45 OTH – the vibe is amazing, friendly community of like minded people, the trainers are the best and always supportive, the workouts make you feel good. I must say in the last 5 months I’ve seen changes & improvement with my physical strength, eating habits and mental health.

3 months into my F45 life & the team at One Tree Hill have made training a reality with support & guidance to an A+ level, being over 50 with multiple old injuries they have worked me through these to a point I’m able to actively workout. Great place to come to connect & get healthy.

I’ve been a member for 3 years at F45OTH and can’t say enough about this place. It has an amazing vibe and energy. Everyone is friendly and welcoming and you are surrounded by like-minded people. The trainers will tailor the exercises to suit you. Highly recommend this place.

F45 One Tree Hill is a place for everyone. The workouts are fun, the team are supportive and motivating and it’s a great place to meet new friends. I’ve been a member since August and feel fitter, stronger and happier than I have in years… all thanks to F45 One Tree Hill and the team behind the scenes.

Have often been daunted by gyms and their equipment. F45OTH has exceeded my expectations. They are professional, supportive and encouraging.I love the different workouts and the challenges to keep you motivated. Its nice to go to a gym where they know your name and you know theirs. Amazing place if you’re looking for a community family-vibe gym

If you want to work out or just make new friends this is the place!!! Trainers are so supportive with EVERYTHING. No matter if your just starting out or been working out for awhile! Fun,exciting, amazing environment and always something new each day… F45OTH is the BEST in town 🙂🙂

Daphe W

I have never felt so excited to workout each day. F45 is such a friendly environment, the coaches are super helpful and they really do help you push yourself further. F45 has made me become more happier with myself and how I feel when I workout. It has also given me a lot of confidence to do things outside my comfort zone. Try a class you don’t know what your missing out on.

F45 One Tree Hill is a fantastic community that supports and motivated you to achieve your best. The trainers are very knowledgable and always make sure the gym is an enjoyable place to be. Can’t recommend them enough!!

The F45 OTH team is the people you want to be around with if you want to start a healthy lifestyle. Did my first challenge and happy with my results. Can’t wait to join the next one! Wouldn’t have done it without the support of the trainers- in and out of the gym.

Nyssa N

I lost over 6kg in my first 3 months after being unhappy with my post baby body for 2 years. Wish I had signed up sooner. I truly didn’t believe it was possible for me to lose the weight or change my habits. It’s about making connections with other people on the same journey as you, and getting the expertise and support from the super friendly trainers to make sustainable lifestyle changes.

Katie W

Words can not describe how highly I recommend this gym. I’ve trained at multiple F45s over the past 5 years in the UK and Australia but nothing compares to the team here at the OTH. The trainers are next level attentive and learned my name on the first day and never forgot it, i feel very seen and catered too which makes wanting to go all that much more encouraging, and not only that, the people that go are all so friendly and you feel like you are apart of a little community.
