I was a member at CoActive for around 1.5 yrs and achieved some great results. Special thanks to Matt who guided me throughout with training and especially an eating plan I can still adhere to now. Great job!

In my experience, a good coach will give you some advice on training, technique, and maybe diet if they (and you) are prepared to go there. A great coach does this in a way that you learn about yourself and your body. The team at CoActive did this with me and on reflection, its this that enabled the hardest thing - sustained behaviour change. Having been plodding along for years, I learnt more about myself, my body and what it takes to get results in the time I worked with CoActive. I highly recommend Matt, Roan and the team for anyone that feels that the time is now to make that change.read more

I love this place, the atmosphere is fantastic and the classes are a lot of fun.... a word I never thought I’d use about exercise!! The trainers have the ability to push you whilst making sure your technical form remains spot on. Highly recommend

    On my 40th birthday I set myself a goal to reach 50 in better shape. I ran, I cycled, I belonged to a gym but there was a steady increase in weight that I couldn’t ignore. 8 weeks with Matt and Roan has achieved more than the last 9 years put together. A concentrated expert approach to weight training and nutrition has pushed me way beyond anything that I could have thought possible.

    Since joining Coactive I actually look forward to my workouts. All the equipment and facilities are excellent and the programmes are totally unique and tailored to the individual. This is no ordinary gym. If you are looking for a results based high end programme then this is for you. The team are able to help with all aspects of your life from dietary through to lifestyle to maximise your programme. I could not recommend this gym enough.

  • Dom Richardson

    I immediately loved the training… it was really hard, in fact seriously hard at times, but I was stunned how quickly the results began to show and how my body reacted and gained strength. The education around nutrition and supplementation all made complete sense and again the results were incredible. My friends and colleagues were commenting not only on my weight loss but also the radiance of my skin and overall being. I had never ever realised what my body was, and indeed is, capable of!

  • Jenny Collar

    Before I started training, I was struggling with knee, hip, back and shoulder pain. I was in low mood, as nothing I did seemed to change this. In a short space of time, I am pain free and I feel fitter, considerably leaner, stronger and healthier than I have done in years. Significantly, family and friends have noticed the positive benefits to me from this style of training.

  • Kirsten Ward

    Kirsten Ward

    The CoActive team started me off slowly and introduced 1 new change at a time, importantly they didn’t throw everything at me in one go – this I believe was one of the reasons why my journey has been so successful. They managed to break my cycle of constant diet failure by starting with setting out a proper nutrition programme. After 4 months of personal training I wake refreshed, I eat healthily and I have lost 16kg / reduced my body fat from 46% to 23% in 4 months. But most importantly I can honestly say they have transformed my life – both personally and physically.
