I feel like I'm more a fan of tennis rather than it being men's or women's. I enjoy watching doubles as well when it's on. I think that there are certain players that I enjoy watching on the men's and women's side. There's some players that I don't enjoy watching on both sides.

I just enjoy watching tennis. And there's things that you can learn from the men's and the women's game.

Earlier in my career, I used to spend a lot of time practising my tennis on court. Now I've learned that it's better to do just a couple of hours on court and two gym sessions a day. That's what's made me fitter and stronger.

My speed is something that has made a difference to my whole career. When I've felt quick and I'm moving well, it makes a huge difference to my entire game. When I feel a bit slower, I end up doing a lot more defending. When I'm a bit quicker to the ball, I feel I can attack a lot more.

I've always hated exercise, but because I've had problems with my back, I now do Pilates, and I walk a lot.

I'm the only one in America who belongs to the 'Cure Cancer' party, so if you give money to cancer, like Harry Reid and Max Baucus, some of these guys really helped us raise big money for cancer, I give them big money for their reelections.
