  I have been training at GT Fitness & Performce for almost 6 months now and I feel it is the best decision I have made. George, Jake and other members at the fitness have made me realise the importance of working out the right way, especially so, in case of beginners like me. Apart from the one-on-one sessions, I also get to learn the right way of working out by observing trainers train others.

Most importantly, the sessions here are designed as per one's body type and its need. I have been more energised, have clarity of mind, am more flexible and am sleeping better. I highly recommend this centre to everyone.

  I was looking to get back into the gym after injuring my shoulder, so I reached out to GT Fitness. I heard back from them immediately and was offered a free consultation.

George listened to my goals and explained their holistic approach to their training and dietary programs, he reassured me that they would be able to help me strengthen my body and lean down safely post injury. I was instantly swayed to sign up.

George paired me with Jake, we have been training for a few months now. Jake is extremely knowledgable and has helped me tremendously in perfecting my form and strengthening my body and injured shoulder. I have seen centimetres drop down but most importantly have regained the confidence to get back into the gym without the fear of re-injuring myself.

I HIGHLY recommend anyone looking for excellent PTs who know what they're doing!

  George has changed my life! I first went with severe arthritis knee pain and needed to get some help for my fitness and wellbeing (esp after my breast cancer surgery and medication side effects). I didn’t know if would be active again and be able to exercise and feel better. George has  helped me so much in all aspects of my health. Advice around food, exercise, supplements and my overall health. He has been training me one on one and makes sure I am safe and effective in building strength and mobility! I am so happy with my experience and I would highly recommend George and his gym to anyone looking to improve their health and well-being.

  I have been training with George for a while and can honestly say I would highly recommend him to anyone just starting out or trying to get back into training! Not only has he helped me with achieving some of my fitness goals; he has helped me with other aspects of life such as having a healthy work life balance, healthy eating habits etc! I think he is fairly priced with how much knowledge comes from him.
