How I work

I use a fantastic system for clients called the coach for life. First we Start with 1:1 personal training session around 12-20 During these sessions I teach you how to master the basic movements of Crossfit. After this If your ready you move to a group Crossfit class I coach and I continue to work closely with you but you also now get the added bonus of being part of the community at my gym. Long term its a really cost effective solution as its cheaper than personal training and much more fun and gives you a sense of purpose.

Crossfit is a fantastic way to get fit and is suitable for all levels and abilities from complete beginners. It also gets fantastic results.


I enjoy all sports but my main sport is rugby. I am currently playing for Shelford rugby club which is a great local club and has four teams therefore caters for any level.



I really enjoy a good challenge. I find by challenging my self I am better adept at inspiring my clients and helping them find goals and their own challenges.
