My worst flight was flying between Macau and Osaka in 2007. The turbulence was so bad that the cabin crew were assuming their crash positions. I had more than a bit of a sweat on.

Motivating yourself, I think having big strong legs, that's pretty cool. Having a big VMOs [the teardrop-shaped muscle above your knee] is always nice. But, the thing is, when you see guys who are clearly gym junkies who only do bicep curls all day every day, and you see them walking down the street ...'Mate, what about the legs?'.

For getting lean and trying to get toned, it's not about having a low weight and maximising as many reps as possible.

I know a lot of people in Phoenix, so I've had some great nights there. It's always hot, too, so it's just a nice to be outside in the evening.

Take noise-cancelling headphones, a good book, and wear comfy clothes.

Nearly anything you need to get at the gym you can get naturally.A lot of training I do is running up hills, running up steps, just in the woods behind my house. Jumping on to things. All these things you can do anywhere, you don't have to go to the gym.

For whatever reason, people aren't taught that sugar is a massive enemy.
