Personal Trainers

I’ve been training at Definition coaching with Justin for almost 10months now and cannot recommend it highly enough! I was ready to make changes to meet my goals but didn’t know where to start or how to achieve it. Justin has been amazing! He is supporting me to meet my goals and has been incredible at guiding me through the training but also supporting me to keep going through life’s inevitable ups and downs. I’ve really enjoyed all the sessions (I never thought I’d enjoy going to a gym) and have found the gym and all the coaches so welcoming. Looking forward to what the year ahead will bring! - 4/14/2026 

I have been training with Justin for over two years now and I found that, following his guidance, advice and encouragement that the positive results came about surprising quickly. Justin provides an exercise plan which is tailor-made to each individual and bears results.During a skiing holiday, I was unfortunate enough to sustain an ACL injury a few months after starting training but far from putting an end to it Justin coached me through this, adhering to the physiotherapists advice, and his own knowledge of human anatomy, I’ve come out the other side feeling fitter and stronger.Justin is a consummate professional, honest, reliable and fun to work with! I could not recommend him highly enough. - 4/12/2026 

I absolutely love training at Definition. I train with both Justin and Carl, and they are fantastic. Genuinely down‑to‑earth, kind‑hearted people who truly care about what they do. They’ve helped me get into great shape, and I’ve made some really good friends through training there. The sessions are often the highlight of my week: we work hard, but there’s always plenty of laughter along the way. I’m incredibly grateful to both Justin and Carl and couldn’t recommend Definition highly enough. - 4/09/2026 

My husband and I joined Definition last year because we needed a kick start. What was initially intended to be a short-term thing, has turned into our favourite hour of the week as we love going and training with Justin. The team are really encouraging and knowledgeable and we have both seem fantastic changes in our body. - 4/06/2026

Approaching Justin to help me work on my weight and fitness aims has turned out to be an excellent life decision. It took months/years for me to commit to any form of training, because I knew I had to mean it and be ready to make some difficult changes. I would have really struggled to know who to put my faith in. However, we met Justin at our own business and my husband and I really respected how deeply proud he is of his clients. There is no ego about him, he's dedicated and takes obvious pleasure in his clients satisfaction at achieving their goals. Plus he can show you his work, the results board of body transformations, and it's impressive. My own experience of getting out of shape was that the longer I put off doing something about it, the more I felt (and saw) it gradually getting worse. At 52, the idea of trying to get in shape (again?) started to feel intimidating. Just an uphill struggle, and my definite resolve to take action seemed to always be at some point in the future. So lucky that we met Justin! I don't know if he knows it himself, but he is very sensitive to what people need. He's also extremely knowledgeable. Once I committed, it wasn't even hard getting into it, just a total joy. I actually loved the time in the gym from day one. In a few months I've achieved results I've not achieved before in my adult life. Plus, seeing definition starting to appear in places where I've never had any is the biggest motivator to continue. The results are coming steadily and most importantly, for me, it feels sustainable. We've met all the coaches and witnessed them working with other clients, and I can confidently say their professional standards are extremely high. Plus they're friendly, they're approachable, warm, human, and committed. I love that they keep in touch, and massively support you through the entire process, if you need it. What I'm enjoying the most . . . the muscle shapes in my arms, having a 27" waist (6" lost) fitting into old favourite clothes that I haven't been able to wear for 10 years or more. I feel like I've found something I thought I'd lost forever. - 10/21/2024 

Highly recommend. I have been training with Justin for 3 months now and seeing results fast! You are paying for super bespoke training and support depending on your specific goals. Justin’s years of experience in not only coaching, but competing professionally, has given him a wealth of knowledge to share with clients! Friendly and inclusive training facility. I have never lifted weights before and felt completely at ease from the start. - 4/02/2024 

Carl my trainer is asolute brilliant! l needed to build muscle as prescribed by my doctor, and l was keen to get stronger too. I am 64 and have never been this strong, and so happy that l see defined muscles now. The trainers are all friendly and approachable. - 1/02/2024
