Hi, I am Billy Byrnes, Owner, and Director of ActivelyBurnz. I’ve grown up with health and fitness as a part of my life. I played cricket, rugby league & athletics as a child, and throughout my teenage years. As I got older, I started training in the gym to focus on strength, building muscle and bettering myself personally.

ActivelyBurnz was founded in 2016. I am passionate about helping, motivating and teaching all types of people. For me, it’s all about self and lifestyle improvements, no matter what size, shape, or mindset you may be in.

When I say ‘Everyone’s Fitness’ this is the statement I proudly stand by. I will STOP AT NOTHING to help you achieve your desired goals.
