Personal Trainers at Riverside Cardiff


Hi, my name is Jamie Arnold, my passion for health and fitness began at an early age, as I competed in various sports, such as Football, Athletics, Swimming and Gymnastics. Having such a strong passion for the health & fitness has led me to working in the industry today.

My mission is to help, guide and educate individuals to achieve anything that they set out to do. I truly believe that training is all in the mind and being consistent is the key to your success. With my 360 approach I can install confidence in you and bring that special something out of you that you never knew you had.

If you are looking for weight loss, fat loss, sport specific training or searching for that confidence and education to be able to train safely and effectively all by yourself, then I am the coach for you.

With my constant desire to further educate and better myself in my field of work, I can guarantee I can help you with all your personal training needs.

“Jamie’s knowledge of nutrition, training & mindset is unbelievable. He built me an amazing program that targets exactly what I wanted to achieve. The confidence I have gained in such a short space of time now means I can go to the gym and train by myself & that is big for me.”
