    “I have worked with George for 2 years now and my results in the gym and on the pitch have continued to get better. I have got much stronger and more powerful as well as staying as fit as possible. George has also helped me with nutrition and my recovery routine to enable me to be able to perform at my top level consistently. He creates sessions specifically for my needs and my body. George has always gone the extra yard and put in the extra effort to help me reach my goals. I would recommend George to anyone wanting to improve themselves in any way possible.”

  • Young shirtless male athlete with gray sweatpants standing in front of a kickboxing event banner at a sports venue.

    Harry McDermott, online client, National and International titles in Kickboxing

    “When I started working with George I was still competing in kickboxing. Under his guidance on training and nutrition, I won national and international titles and even dropped 10kg in 12 days for a weigh in! Since then, I have returned to tennis and have entered a hyrox competition. Can’t recommend highly enough”

    “George is one of the most driven, knowledgeable and hardworking fitness coach i have worked with. He will always go the extra mile to make sure you have everything you need. During the last few years of my career, George looked after me, and with his individual approach, that’s the best I felt for a long time. It allowed me to perform until the end and because of it, I extended my career for a year longer than I originally planned. But even since I have retired, he has been sending me weekly individual programs, around my needs and my new schedules. George is great, with him you can be sure you will get the best support you need to achieve your fitness goals.”

  • A soccer player in a red uniform with the number 10 on the jersey, playing on the field with a soccer ball.

    “I had the pleasure of working with George for 2 seasons. He is very knowledgeable and extremely hard working. One of the best guys I’ve had the pleasure of working with in the professional game. A top-class person that is always willing to go above and beyond to help and improve people in whatever aspect that is.”

    “Before working with George, I was full out boxing, no real strength work but always beasting myself. We have been working together for some time now and I have had great improvements in my conditioning and strength, he is easy to work with and helps me understand the body and the benefits of the work we are doing together. Any issues I ever have, aches pains or questions he’s always there in an instant and takes time out of his day to check up on me and how I’m getting on.”
