Greg Rusedski, is known for having one of the most powerful serves in tennis.
So who better than the British star for some tips to aid your own serve.
The key to building my serve was making sure I had a good ball toss.
When I was younger, my dad used to mark a little circle on the floor so that when I tossed the ball it would always land in the same place.
Then we worked on tossing the ball to the right height.
If you watch most good players, they can always throw the ball up and it usually comes straight back to the same hand.
I started serving when I was about six-and-a-half and I was quite fortunate that it was quite natural for me.
Then through hard work I had a pretty good serve since the age of nine.
It's important to make sure you have a nice, smooth action where you can do the same motion consistently.
It doesn't matter what grip you have, but just make sure you can do the same thing over and over. It comes through repetition basically.
What you need to do is make sure your arms move together when you're doing the toss so they work in tandem.
If your toss is all over the place then your arms are going to move differently and you'll have inconsistencies.
Concentrate on the toss and on getting up on the serve when you're hitting it.
Most people think that you have to bring the serve down fast, it doesn't. The arm will naturally bring the ball into court.
So keep on accelerating up on the ball and use your legs to generate more power.
I always had a fast serve but I didn't always have the control!
When I was about 10-years old I developed this by spending hours serving bucket loads of balls and placing targets down on the court for me to hit.
I'd put a target on the backhand on the 'T', one out wide and one down the centre of the service box.
To begin with it's usually easier to aim down the centre at your opponent's body.
Then you can work out towards the corners while getting your first serve in.
