I’ve been lucky enough to be nominated for 9 different awards to this point for the level of coaching and results I provide. From local awards to being nominated at the UK wide award “The Great British Entrepreneur Awards” in Mayfair, London. All of which is still pretty mind blowing to me as that’s something I never set out to achieve.”

 This year will be my 10th year as a coach and business owner, running OlsenFitness!!

I often get asked about what exactly I do, so here’s everything, some of which you may not have knew about me or OlsenFitness. I’ll also post a few more bits you may not know in the coming weeks…


  • I work half of my time with Weightloss, Fitness & Health related clients. Helping clients become happy, healthy and confident whilst teaching them how to sustain their result

  • I spend the other half of my time working with sports clientele from grassroots to international standard. I’m passionate about providing a high level of S&C (up to professional & Olympic standard) to people who don’t have that offered at their club and want to realise their full potential.

  • I’ve been lucky enough to be nominated for 9 different awards to this point for the level of coaching and results I provide. From local awards to being nominated at the UK wide award “The Great British Entrepreneur Awards” in Mayfair, London. All of which is still pretty mind blowing to me as that’s something I never set out to achieve.

  • I’ve worked with doctors, teachers, police & fire service, shop workers, actors, actresses, directors, office workers, MP’s, I feel incredibly lucky to have worked with so many great people!!

  • I’m also lucky enough to have built up a great network in and around the UK of fitness professionals including physiotherapists who refer clients & athletes to me for strength and conditioning post rehab.


Sometimes it’s great to look back and reflect to make the future even bigger & better!!

The next goal for me at OlsenFitness is to make OlsenFitness the leading community in South Wales for anyone wanting to improve their physical, mental & social health whilst achieving their physique goals!

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!

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!

I have been with OlsenFitness for a few years now. Before working with Kier, I thought I was fit for hockey and didn’t think I could do much more to improve my fitness levels. However, since working with Kier, I have become stronger, more agile, and more confident on the pitch.  He has helped me train smarter. He believes in his clients; he’s encouraging and supportive and is always available to discuss any issues or concerns around training and nutrition. Thank you OlsenFitness!

I have never been someone who enjoys the gym, I also dislike running but health & fitness is important to me.  I initially joined small group training Kier ran & fell in love. They were engaging, every session we did something different, it was challenging in strength & fitness & before long I started to notice changes in my physique. Before lockdown I took the plunge & started 1-1 PT sessions & I have never looked back. I am continuously learning about the balance of life, nutrition & training. Kier is the most friendly person ever, he works with your lifestyle & together you can start to achieve. I am now lifting weights I once thought were for body builders! I am growing in strength & fitness, my knowledge around nutrition is improving & so is my physique.
