About Carl

Since a very young age Carl has had a keen interest in many sports and fitness activities. He loves the community side of sport and fitness which is the reason he found CrossFit.
Multiple looks on the internet at the growing CrossFit community and the (on paper) innocent look at some of the workouts initially caught his attention.
Since 2012 Carl gave up his old working life as an IT professional to pursue a career in health and fitness, changing other peoples life’s for the better.
Starting out at a traditional global gym as a PT he grew a large client base and started putting them through CrossFit based workouts.
With the client base’s ever growing size and their fantastic results, Carl and Claire looked to take their clients to a better CrossFit environment and on the successful pass of the CrossFit course opened ‘The Box – Portsmouth’ home to ‘CrossFit Portsea Island’ in September 2013.
