”I train with Mark because I believe if you want to be the BEST you have to train with the BEST! When I get in the ring, I want to be confident that I am stronger, faster and fitter than my opponent and training with Mark and his world-class trainers gives me this confidence.”

About Mark Section

HI, I’m mark Ottobre

I’m a globally-recognised body transformation educator and mentor, and the founder of Enterprise Fitness. 

Over the last decade my team and I have trained 300+ first-place winners in bikini, figure and physique competitions, as well as Commonwealth Games gold medallists, Olympians, and even a former Prime Minister.

If you stepped foot in a Melbourne gym in the early 2000’s you probably walked by me training at some point (sorry if I was hogging the squat rack) on the path to winning Melbourne’s Strongest Man (under 90kg class) and competing in multiple bodybuilding shows.

Now, after two decades in the trenches building my knowledge and business, I’m on a mission to share what I’ve learned, raise the standards of personal training industry-wide, and instil the mental edge that creates champions in and out of the gym.

The truth is, the majority of people have the right motivation but the wrong mindset.

Most People Treat Health and Fitness as a List of Things to Do Instead of a Lifestyle to Practise.

If you’re like most people, you don’t need a better diet to get in shape. Instead, you need to learn and develop new, daily practices. Those practices become habits, those habits form patterns, and predictable patterns create long-term sustainable results.

My unique philosophy of training, nutrition and supplements works alongside a shift in your mindset that delivers lasting change. 

Over decades, my methods have proven to help people achieve what they thought was impossible. The combination of training, diet and mindset has led to transformational results… both for everyday folks wanting to transform their bodies and health (see Enterprise Fitness’ hundreds of 5 star Google reviews), and for elite athletes and trainers wanting to level up their results (just see Enterprise Academy’s Success Stories).
