Fantastic experience: Jon is the best of the best. I had a microdiscectomy 2.5 years ago and needed to strengthen not just my core, but my entire body.

Fantastic experience: Jon impressed me immensely with his excellent knowledge and insight. I initially had very little idea of what kind of service I was looking for, but knew I wanted to get fitter.

He is the one trainer who finaly managed to get me motivated to do a weekly cession which is no small feat! He always knew when to push me or not out of my comfort zone and he’s an extremely nice and knowledgeable individual. I enjoyed every one of training cessions and will miss them a lot.

Fantastic experience: Great workout! My father workout with you and had amazing experience. Thank you

Fantastic experience: I cannot agree more with the other positive reviews about Jon, my personal trainer. Jon's ability to motivate and inspire his clients is truly remarkable. From the beginning, I was hesitant to start exercising, but Jon was patient and understanding, taking the time to explain each exercise in a way that was easy to understand. What sets Jon apart from other trainers is his genuine care for his clients. He truly wants to see them succeed and will go above and beyond to help them achieve their goals. Thanks to Jon's guidance, I not only began to care about myself and my body, but I also started to enjoy exercising and look forward to each session. Overall, I cannot recommend Jon enough.

Fantastic experience: Jon is a great PT to work with and tailors his approach very much to your personal needs. I had a suspected injury and specific physical goals and sessions were perfectly tailored to improving the injury and growing my upper body strength. Through Jon's support, my injury very much improved and I saw physical changes in my upper body, not to mention a clear improvement in strength. I highly recommend working with Jon :). Isabella McCoy

Fantastic experience: Great trainer with lots of experience and knowledge. After a big shoulder injury I felt unbalanced and unable to push myself safely in my training and wasn't able to get the same results as previously or lift like before the injury. Jon helped me safely gain my confidence using heavier weights and challenging myself more again and to change up my training to really get my body in a better shape than I had achieved before and maintain it.

Fantastic experience: I reached out to Jon expecting that it would take days if not weeks to agree and fully set up a 12 week transformation plan. I was very relieved when Jon and I managed to meet for an introductory session without fuss with full transparency around costs and expectations unlike other PTs. Now that the 12 weeks are coming to an end, I look forward to continue working with John and would definitely recommend him to anyone who is looking to/takes fitness seriously and to that extent is seeking a mentor to take them to the next level. Over the course of our program, he demonstrated excellent knowledge in training physiology and nutrition as well as implemented and oversaw a program that has helped me become smarter, fitter, healthier and stronger!

Fantastic experience: Jon is a fantastic PT. I am really pleased with my progress since we have been training together!

Fantastic experience: Sessions with Jon are more than just a work out. I'm being educated on the why which will help the weight loss changes I'm experiencing become consistent rather than a short term fix. I'm learning how to make this fit with my lifestyle so I don't feel like I'm missing out.

He has a very long experience that will help anybody to reach their objective. Very impressed by the whole experience, thank you for your amazing support and deep knowledge.

Fantastic experience: Top

Fantastic experience: I've been training with Jon for 18 months. He's technically excellent on all aspects of fitness and diet. This includes demonstrating the correct way to do any exercise with or without weights, and how to tweak it to maximise its impact, and will always explain and discuss the purpose of the exercise. He is thorough and always focused 100%, and has plenty of initiative to vary planned routines or exercises if circumstances require ie muscle strains. Plus he's a nice guy too. Highly recommended.

Fantastic experience: I've been training with Jon for around 4 years. He's very experienced and knowledgable, and helped me with rehabilitation training post a knee operation and manages to keep training varied and fun.

He manages to tailor the training to keep it interesting and avoid injury, and gives great advice on nutrition and other fitness and training initiatives.
