Jack is THE BEST!
He has fixed my knees when no other PT, doctor, physio or chiro could! I am pain-free and stronger than ever.
He teaches/supports the importance of mental health and the HUGE benefits the gym gives this, as well as all-over 'fit for function' fitness. He is totally flexible to your preference and includes huge variety in his plans so you're never bored/overly-challenged. He is friendly, approachable, knowledgeable and the best PT I've ever had.
I am a qualified animal physiotherapist and I still learn from Jack every week and never plan on leaving him! Thanks Jack!

Review: 25kg Down in 6 Months with Jack Cardy Fitness. Life-Changing Experience!
I can confidently say that working with Jack Cardy Fitness has been one of the best decisions I’ve ever made. In just 6 months, I lost 25kg — and more importantly, I’ve completely transformed the way I approach health, fitness, and self-discipline.
Jack’s coaching isn’t just about workouts and meal plans. It’s about mindset, structure, and consistency. From day one, he took the time to understand my lifestyle, goals, and limitations. The training was challenging but always manageable, and the nutrition plan was realistic and sustainable — no crash diets, no gimmicks, just real, honest work with professional guidance.
Thank you, Jack, for helping me find the best version of myself.

I have been training with Jack for over 3 years now.
During this time he has taught me how important is the correct form doing exercises and using equipment in the gym.
His training sessions are not just about how to get physically stronger but also how to have the right mental attitude to reach your goals.
I started training with Jack because I wanted to become a better, stronger and faster runner. I have learnt how important strength training is to avoid further injuries whilst running longer distances. When I started training with Jack I had one injured knee and during one of my runs I fell and injured another knee (my own fault). Jack knows a lot about injuries and has shown me how stretching and foam rolling before and after running helps to speed up recovery.
If you are looking for a personal trainer to achieve your goals then Jack is the best!
