Also, to be honest, my dad wanted me to be an athlete. And I think all sons want to prove something to their dad. So now, aged 35, I want to see what I can achieve physically.

I'm one of five kids and we lived on a massive farm in New South Wales with my mum and dad.

Dad, I'm in some trouble. There's been an accident and you're going to hear all sorts of things about me from now on. Terrible things.

My dad's a bodybuilder. My whole life I've been taught to train the hard way. I believe in earning strength, not buying it. My grandfather raised me old school: In baseball, you work for whatever you get.

My background is basically scientific math. My Dad was a physicist, so I have it in my blood somewhere. Scientific method is very important to me. I think anything that contradicts it is probably not true.
