At the age of seven I started to play rugby and carried on until a serious injury stopped me at age 28. I have played in the lowest leagues, the highest leagues, lots of representative rugby and played for fun, semi-pro and fully professional. After playing rugby I got into boxing and weightlifting, always looking to take on the next challenge. At the age of 41 my ankles and knees were at their worst and I was ready to do something about it.
