Meet the Team

We are a husband and wife duo who share a love and passion for keeping active and maintaining a healthy, balanced lifestyle. 

Our fitness journey began in 2012 when Tim first qualified as a Fitness Instructor and launched our first ever outdoor Bootcamps, which were a massive hit! Karlene would often help out with the sessions, alongside working her part-time job, but later decided to take the leap and quit her job to qualify as a Fitness Instructor herself, before coming on board On Fire Fitness, full time!

We are incredibly proud of the community we have built and absolutely love what we do, which we hope shows, through our practise and our dedication to bettering the lives of our clients.


Founder of Onfirefitness,Tim has taken to a love for Kettlebell training, a unique form of exercise which combines traditional forms of training, with a modern twist. 

With 10 years of experience in the health & fitness industry, it’s safe to say that Tim is a fountain of knowledge and has a broad range of understanding of individuals’ needs and goals and how to help you reach them.
