In tennis it's easy to get greedy - and one Grand Slam doesn't feel enough any more.

People think that there is so much money in tennis, but the reality is unless you're ranked in about the top 50 you don't earn much at all. It is hard to support yourself travelling the world, to be away from home most of the year and to pay for a coach to help you become a better player.

Core strength and stability is very important to me. Tennis is all about rotation of the body and my ability to create power. I incorporate a lot of abdominal, back and glute exercises into my gym sessions.

You hear a few people saying that, you know, maybe some of the past male players like to watch me play or whatever else, just because I play a bit differently and maybe they can relate to it a bit more with a bigger forehand rather than a backhand, good serve and whatnot.

Tennis takes care of everything. It requires agility and quickness to get to the ball, core strength to get power into your shorts and stamina to last for an entire match. In addition to toning your arms and shoulders, it's a total body workout for your legs and abs, and works your heart and core unlike any other sport.

Daniel, my big brother, is eight years older. I'm lucky he didn't mind hanging out with his little sister and my younger brother.

It is never too late to get into tennis! While I started playing at the age of 8 when my parents gave me a tennis racquet for Christmas, tennis is a lifelong sport that can be enjoyed by people of almost any age. It's also something you never forget once you learn.
