We play at the world's most beautiful beaches but in the world's most challenging conditions. It is not like you play one match and you go back to air conditioning. We do it all day long.

We play at the world's most beautiful beaches but in the world's most challenging conditions. It is not like you play one match and you go back to air conditioning. We do it all day long.

The first thing I do when I get there—like all of the players on tour—is apply sunscreen. One of the few hazards of the job is the wear-and-tear our skin takes from the sun.

The exercises helped get the flexibility back in my ankle and also increased my overall flexibility. As I was getting into my 30s, I wanted to do everything I could to improve my longevity.

I don't have to get myself pumped up or calm myself down. As we get into the later rounds of a tournament and there is more at stake, I have even more adrenaline. If we make the finals, it's just an extra opportunity to win a tournament at my age. That doesn't come along that often.

It's a serve and pass game.

When I warm up now though—especially on center court—there is usually music playing, so I don't really mess with music.
