Great trainer and great guy! Knows exactly how to push and encourage you to reach your goals. Full of knowledge, ensures that you are also learning the reason why when running through strength and technique drills. Can’t recommend enough!
Personal Training Cardiff Testimonial - Abby Hill

I have been doing PT and small group training with Kier for years now! He is the best PT I have ever had, and I have tried a few! Not only is he motivating but he listens! Sometimes being a counsellor as well as a PT. He is always pushing me to do better and is such a great guy! If you are looking for small group training or 1-1 PT then look no further! He's the best!

“At OlsenFitness our belief is built around the following questions…making someone look great is easy to achieve, but what if you got to that goal and didn’t feel great, didn’t enjoy what you were doing and didn’t know how to sustain those results?


"My coaching focuses on improving the 3 pillars of health, Physical – your physical health & how you look, mental – how you feel and social – being part of something more, having that accountability and being part of a team full of people looking to achieve their own goals.”


“I know I’ve done my job well when a client doesn’t NEED me anymore but wants to stay for the community, the culture within the team and being part of something that pushes people to be their best.”
