Fitness is easy to achieve but very difficult to maintain. Therefore, it becomes a life-long process which you have to live with and need to be extremely disciplined.
I used to own two gyms in Delhi called Breathe, so obviously I've entered a gym, but I don't use a gym for fitness.
In my view, fitness training isn't that important in England, as they all train with such intensity anyway and have a competitive edge when just sprinting. The matches are all hard-fought, too.
I've always been obsessed with health and fitness and hence been a firm believer that change needs to begin from the inside!
I've had one very bad ankle injury but otherwise I've been incredibly lucky with my fitness. I've worked hard at it and I've always been fit even compared to other players. That sustains you through various parts of your career, but I am 36.
As the issue of youth fitness - from obesity to proper exercise regimens - takes on more resonance in schools and communities across the country, CrossFit Kids and other preschool fitness programs are raising questions about when and how children should start playing organized sports or hitting the gym.
I've got to get my cardio up. I'm usually known as the fitness guy on the Stanford team, but not 70 to 80 plays a game, so I've definitely got to step that up. But I'm all about it.
I was playing basketball at Lifetime Fitness every day for two hours. Like, I played an hour of basketball before I played David Ferrer in the semi-final.
I see a fitness coach three times a week and I do a lot of boxing, a bit of running when my knees let me, circuit training, fit ball, anything that will keep my heart going and stop me getting even fatter.
Making fitness a priority will energize you, make you look and feel better, and help diffuse stress.
When I see these kids 6 years old with a private coach, and at 7, they have a fitness coach, I'm like, 'Aw, come on.' At 12, it's for sure they will lose all the interest in tennis because they do not interact with other kids.
Overall, I think I'm in pretty good shape, but I'm not really someone that is gung-ho or a fitness fanatic.
I love this planet and I feel that depriving yourself from anything which this planet has to offer is taking you backwards on your road to fitness.
A typical week of training leading up to a major championship is like the sprinkling of parsley at the end of a dish. It's just the final little touches, that last little bit of strength or fitness, but mostly you are ready and are just maintaining and staying healthy.
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.
I am quite a fitness freak. I may not have the time to sleep, but a workout is a must. I have even set up a small personal gym on the sets.
My fitness trainer's English, my physio's English, some of my friends are English. I don't have a problem with English people at all.
I used to be very into fitness and would happily pose for photos in my bikini. Now I look at those and think, 'Where did that body go?' But that was before children.
I grew up watching Salman Khan and Arnold Schwarzenegger, who have always juggled fitness with acting. In real life, I'm a fitness freak. Besides, it is nice to look at an actor who is fit, and if you become a role model, that's a perk.
