The psychology of sport is so important. When you are standing at the crease, in front of a stadium full of people, it's a pretty intense experience. So you need to have the psychological tools to control your mind and deliver your best performance.

I enjoy fitness. I've always enjoyed trying to stay healthy. I've enjoyed all my gym work; obviously there's a cross-over with that going into cricket. But you also talk of finding an escape and I think in the last year or so, running has provided me with that.

The fact that people want to learn from you gives you confidence as well, especially if someone in an IPL dressing room that you respect comes up to you and asks how you do something. Your self-worth starts to improve.

I love Japanese food - it's a really healthy way of cooking and it is very easy: I often just steam the vegetables and fish together, make a space for the noodles, and I have a great healthy meal in 15 minutes.

I have learned a lot of interesting things about nutrition in my cricket career but the biggest lesson of all is to ensure your healthy eating habits are sustainable. The best way to eat healthily is to think of nutrition as a lifestyle, not as a diet.

We all have our food weaknesses and mine is snacking. I have a sweet tooth and I love chocolate. But I have learned that if you plan ahead you can get round that. I always carry a few chocolate-flavoured protein bars when I'm travelling.

Although I train hard with England and Rajasthan Royals, when I am at home in London I always like to join some group fitness classes and experiment with new workout ideas.

One of the main things that stand out for me is the mentality of the best players. They really want to be in those big moments, have the responsibility, the trust in themselves and the self-belief.

We hear about the importance of strong core muscles all the time, but it never quite hits home until you stop and think what the muscles around your stomach and lower back really do.

Some days if I am not feeling great or I feel a bit down or anxious, I just go for a run and I instantly feel better. Despite all the technology we use in training these days, it remains an amazingly simple way to energise your mind.

I know that fitness helps me to be better at everything I do and to live my life in the best possible way, so it has become a genuine passion, even outside of cricket.

I've been lucky, my wife's been amazing. Any time we've had cricket matches she sends me to the spare room to get some sleep. She takes care of everything.

It's an amazing opportunity to be around at the right time and play in a home World Cup.
