Mark Barrett

Horley Leisure Centre


There are many reasons people exercise, whether you want to improve your sports performance, training for an event, reduce health risks or look and feel better, I can help you achieve your goals. I have played sports to a high level, completed in over 18 marathons and ultra marathons, boxed and more importantly improved my health and wellbeing during the 7 years I've been a personal trainer.
I work with clients to achieve their goals and have had great success over the years. I will work with you taking ownership of your goals, setting programmes, following nutrition guidelines and most importantly making the sessions enjoyable so we can achieve your goals, whilst enjoying the journey.

I've trained with Mark for a number of years now, first starting out with a weight loss goal which we achieved very quickly. He's completely changed my outlook on exercise and nutrition and more importantly my lifestyle. I've started to enjoy running and now compete in many events but continue to have PT with him as it provides such a focus and I know with Mark whatever my goal or ambition he'll help me achieve it.

Sarah, Horley
