AWARD WINNING PERSONAL TRAINING

Made simple for you to 

achieve your goals

Olsen Fitness was built with a strong determination to provide the best COACHING possible in two areas...

  1. To help people ready to make a change in their life, to their health, physique, energy levels, mindset and confidence among other areas. Giving them the coaching, knowledge, accountability and guidance to ultimately live a healthier, happier more fulfilled life. 

  2. To provide a high level of strength and conditioning that athletes would have access to at a professional sports set up to those who play grassroots & semi pro sport. So much potential is left untapped into from those just under the professional level.


Over the past 10 years OlsenFitness has been recognised with 9 awards nominations both locally and nationally. We have helped countless clients achieve phenomenal results helping them lead a healthier life whilst achieving their physique goals. We have also worked with Athletes from grassroots through to those who represent their country in their given sport.

CLIENT TESTIMONIALS
A few years of being a member at Olsen Fitness and Kier has helped to build mass and improve body shape alongside strength and conditioning for wakeboarding, his help and guidance does not stop there as he has helped create healthy sustainable habits around nutrition and training. Top bloke, Top place & it’s a pleasure to be part of the community he has built.

Dafydd Salaman

The best PT I have ever had. I never feel inferior or that I cannot achieve goals. He's personal and I always feel I'm visiting a friend not just a personal trainer. I highly recommend.

Gary Mullins

Olsen fitness is committed to helping you meet your goals, recover and progress. Kier helped me overcome a back injury and get back to where I was. Even post injury I am now fitter and stronger than ever before thanks to Kier.

Andy Hunter

I have really enjoyed working with Kier, he has been easy to work with and gets on with everyone within our team.

Every session we are pushed, but more importantly the training he provides is targeted towards our long term goals – which is exactly what we have been looking for.
