Jason and the team are always amazing. There is always a great variety of training rounds and exercises to keep pushing yourself to your best abilities with the support from the team. They are incredibly insightful, always helpful and up for a good chat and a laugh to make you feel comfortable. Jason and his team are always motivated and keen to push you further and keep you moving, always happy to answer questions and be supportive. The style of training offered is perfect for the entire body, HIIT cardio, strength and resistance, boxing circuits and so much more, they have quality equipment & are constantly changing up the training styles to keep you moving and loving the variety. I've always been focused on being fit and healthy and have trained in so many gyms from local gyms, franchised gyms, specialised training gyms, with PTs, outdoor groups you name it and these guys are the best. Don't miss out on the perfect opportunity to change yourself for the better, push yourself to a place you didn't think possible and have a great time while you do it.

I joined in April 2021 after a week trial with a little push from a good friend. Totally out of shape and hadn’t been to a gym in years. The workouts are varied in the group workouts I attend. Jason and Ash are fantastic explaining the workouts and getting us through them. Jason has created a gym that is friendly and not intimidating. Everyone is greeted by name when they arrive and are encouraged during workouts. If you are thinking about getting fitter this is the place for you.

I cannot recommend Concept 42 enough. When looking for a gym to help me get my fitness back without injuring myself someone recommended Jason and Concept 42. I read some reviews online and they were all true. The gym is ultra-inclusive, unintimidating and the staff are all first class. The worst thing about lockdown has not being able to go to the gym. The whole community has been incredibly supportive. AAA rating!

I love training at Concept 42. We all wander in bleary eyed in the morning and stride out energised and ready to face the day. Jason and his team are honest and hard working and just want us to get the most out of our workout. Can’t wait to get back to the gym, but in the meantime I’m enjoying Jason’s online workouts and making the most of getting outdoors in the green and blue to train.

Jason and the team take the hard work out of work outs. I turn up and am ALWAYS greeted by a happy smiley face that is stoked to see me come and sweet my guts out. I love the way it is modest, humble and above all filled with a community of people who are there for results,. Not for show, and able to help me get results! Love your work guys... I will NEVER train anywhere else!

We love Concept 42. My husband and I have been members for a few years now, and we couldn’t recommend it more. Jason and the team, have created a fantastic environment to work out in. Great variety (strength, cardio and boxing), we always feel challenged but safe, and in a completely un-intimidating environment. Thank you.

The team at Concept 42 are amazing. The workouts are varied and effective, with the trainers who are super encouraging During lockdown, Jason has taken great care to post regular programs and stay in touch, which has been awesome. I can't wait to get back to the gym; it has a great community feel.

So happy with my experience at Concept42! Unique gym experience everytime! I Hadn’t been to the gym in years. The team made me feel welcome at the beginning and comfortable throughout all sessions! Highly recommended for people who want to try something new!

I have been a member at half a dozen gyms prior and C42 is by far the best. To finish each session trainers take great care stretching everyone properly. Members, trainers, facilities and atmosphere are all wonderful. I highly recommend C42 Mona Vale!

Awesome place to train ! Been coming here for a few years now, great mix of classes and workout space to keep you moving. Can't speak highly enough of Jason and team, a super friendly and encouraging environment.

I have been doing F45 for a few years. This is a similar format but better. The coach talks through posture and takes the time to coach you and the class. Jason is an absolute legend.

Super early morning classes! Perfect way to start the day. Always a different workout, smiling happy supportive staff, local and conveniently located in Mona Vale. Highly recommend.

Yvette, Jason and Tess have been awesome in my rehabilitation after my surgery. I feel almost brand New. Thanks guys Martin
