Level 3 Advanced Personal Trainer


I have been personal training for numerous years now, starting at Virgin Active, continuing at Daleon Fitness and now present at the Fitness Locker.

The training modalities used are one of a kind, with unique equipment such as Ankorr and Tytan Belt. You can expect a realistic and professional approach to nutrition and training that will bring results.

I have worked with a range of clients focusing on weight or fat loss, prehab & rehab, sports performance.

I also work with many sports personnel. triathletes, footballers, rugby players, boxers, MMA, motocross/ eduro athletes. 

I run a weekly motocross/ enduro S&C class from “FL” to aid their performance, in which many have gone on to gain more podium finishes.

Alongside this, being linked with Bedlinog RFC to develop and grow their players has been an essential part to their successful campaigns.

For me personal training is personal for a reason. It is so much more than training. forming trustful bonds, changing your life for the better and forming new habits for the better. This isn’t a one size fits all, let me tailor your results to you.
