It's not good to stretch when you're cold. Get your heart rate up, and once you finish, take time to stretch and let your body calm down.
All we see is gym, tennis court, and bed.
I do not follow superstitions on court.
Tennis has given me so many opportunities, and I feel very lucky to have achieved whatever I have, especially coming from a country that does not have a great history in the game.
I like to be alone and listen to music. Every match I play, I have a tune in my head over and over. It might only be a few words or a small piece of the tune, but it can drive you mad.
I like to have my privacy. I don't like people knowing what I do in my free time. I am also a very shy person, but I understand that people want to know more.
