Sion Williams

Hey guys! My name is Sion. Fitness and sport have been a great passion of mine since I can remember. Having been a keen athlete, rugby and golf player, qualifying as a Personal Trainer was a natural progression. Fitness and wellbeing is a choice of lifestyle and I am dedicated to helping you achieve this.

I have experienced firsthand the powerful effect fitness has had on my clients: its notable impact on confidence, self-belief and determination. My qualifications allow me to help clients who require postural retraining and corrective exercise.

I can create a range of sessions and programmes enabling you to achieve your aims in the most effective way. My approach is motivational, encouraging but at the same time friendly: this positive attitude has proved to bring the best out of my clients.

If you see me around the gym, please feel free to come over and have a chat or enquire about a taster session. I am also a fluent Welsh speaker and would be happy to conduct sessions in Welsh if preferred.
