Start your journey to better health & fitness…

CoActive Health was founded in 2015 by two personal trainers who shared a passion for optimising health and training hard. After years of working out of private health clubs and personal training studios they teamed up to create the ultimate private training facility.


Only the best equipment would be used, utilising the best programmes and coached by the best coaches, hence CoActive Health was formed.


If you’re serious about a health and fitness goal we provide the ultimate ‘no excuse‘ environment in which to get you there. Don’t hesitate to contact us today to find out how we can help you achieve your goals!

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.

Gym Facilities

A great deal of attention to detail has been put into making this a fantastic gym to train in. First and foremost this is not your typical commercial gym as you won’t find any cross trainers or treadmills. Instead the gym is designed around movement and strength.


The strength training area is predominantly equipped with Atlantis machines and Watsons bars and dumbells. Both of these equipment providers are widely regarded as the best in the world.

The Movement area is astroturfed allowing for the use of sleds/prowlers and other great conditioning tools. This area provides a great space in which to stretch and move dynamically.


The gym floor also has a shake bar where members can have their pre and post workout nutrition.


We also offer changing facilities with under floor heating and filtered showers.

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.

Our Vision

To be the best personal training gym in country. Here at CoActive we want to be the catalyst that helps people be the best they can be both inside and outside the gym. In order to do this we aim to provide a world class service of personal training that guarantees positive results to every client.

The CoActive Approach

Experience has told us that all fitness goals are built on the foundation of optimal health. It is upon this principle that CoActive Health was formed. CoActive Health utilises a unique system designed around the five elements necessary for optimal health and performance: Nutrition: Training: Mindset: Supplementation: Recovery.

It is impossible to reach your full physical and mental potential without addressing each and every one. It is upon this ethos that CoActive Health works. You may have the cleanest most nutritionally complete diet alongside the best training programme available, but if you don’t have the right mindset then results will not be optimal. Here at CoActive Health we provide expert coaching and advice to help you optimise all of the following elements:


You are what you eat, literally. Our bones regenerate every three weeks, skin every three days, blood every day and the whole body every seven years, so what you are eating now are the building blocks for your future body. We will advise you on your nutritional needs and give you the practical knowledge and strategies to improve your diet forever.


Training is about applying appropriate stress to the body in order to yield positive results. We provide a thorough structural balance assessment followed by intelligent programming and great coaching whilst utilising world class equipment that when combined will help get you in the best shape of your life!


If you want to reach a goal it will require change. Change is inherently uncomfortable and intimidating to most so here at CoActive Health we provide great hands on support to guide you through the ups and downs. You need to believe to achieve, CoActive Health will inspire and guide you towards your full potential.


In an ideal world all our nutritional needs would be met through our diet. However with the advent of industrial farming, pollution and todays heightened stress levels food no longer provides everything that we need. The only sensible way to meet the body’s added demands is through quality supplementation. The market is flooded with supplements promising the world but delivering very little, we only endorse and recommend the very highest quality supplements available.

Rest and Recovery

As mentioned, exercise is a form of stress and so in order for us to benefit from it we must give our bodies adequate recovery between sessions. Sound restful sleep is the cornerstone of recovery. Enough sleep boosts testosterone and growth hormone which help keep you lean and energised. With correct programming and some simple lifestyle tips we will ensure you start each session fully recovered and ready to go.
