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.

I think squats is a generic thing - you can do squats with anything. That's the great thing about it. As long as you get in a safe position to do it.

Probably the biggest thing around not training correctly is eating. You've got to fuel your system correctly, and I think what we're very unfortunate with in this country [UK] is the [lack of] education around food and nutrition.

I compete all over the world, so I travel two or three times a month and spend at least six months a year out of the country.

I love cooking all different things, so any form of meat, fish, anything else. I do have a really strict diet, but it's all protein and veg basically. When you are on a diet like that you have to get inventive, so you have to be willing to try any different fish that's out there. Probably a favourite of mine is some baked trout fillets, on a salad.

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

I generally don't enjoy relaxing and doing nothing on holiday.
