Australia's longest established Private Studio using the CHEK Practitioner Approach to Corrective Exercise

Important COVID-19 / Corona Virus information for Human Engineering.



Hello my name is Chas Barclay and I am the sole owner and operator of my business. In these changing and challenging times, I want to reassure you that my corrective exercise studio is private and each of my clients/patients are thoroughly assessed before, during and after consultations/coaching.


This is done both face to face and via questionnaires. My studio is large enough to uphold the government's social distancing guidelines and I only see clients/patients on a one-on-one basis. I have run this studio for nearly 20 years and I am familiar with all my clients’ health and lifestyle habits. This gives me great confidence in being able to continue delivering exercise physiology and corrective exercise rehabilitation programs in a safe and unique environment. All cleaning /sanitising of equipment, plus equipment purchasing and maintenance is undertaken by myself, so I can guarantee the integrity of the studio and the services that I provide.


I have also just completed the Australian Government’s Department of Health e-learning course in Infection Control Training – COVID 19, which covers the fundamentals of infection prevention and control. This training is available for care workers across all health care settings, including allied health of which Exercise Physiology is one.


Health, fitness and quality of life are my core values.

Never has there been a more pressing time to optimise one's health, exercise choices and general well-being.


My studio is open and will continue to remain open subject to the Australian Government’s Department of Health guidelines, to ensure I can help you realise all of your goals.


I look forward to seeing you soon and should you have any questions or concerns please call me ahead of your scheduled appointment or at any time.

 What Our Clients Are Saying


"Significant lower back pain over a period of 4-5 years, an inability to sleep through the night, and not be able to hold my 1 year old in my arms for more than 2-3 minutes, are all now a non-issue, solely due to Chas's input, advice, and exercise rehabilitation program." 

Damian Ferigo - Finance Manager, Auckland

"My experience with Chas proved to be completely innovative, highly productive and enjoyable. We managed to make more progress during our 3 months together than the combined benefits of years working with various physical therapy and other exercise methods. In addition to providing a radically different approach to therapy, Chas's high energy level and enthusiasm along with his beautiful studio made it fun to train."
