Every aspiring professional tennis player will have heard every trick in the book when it comes to perfecting his or her technique – whether it’s changing one’s grip or studying the other player’s game plan.

But while we can try every tip and trick imaginable, nothing quite compares to good old fashioned advice from the professionals – and who better than the World #1? That’s right – tennis ace and all round superstar Serena Williams is now offering her own tennis masterclasses for the modest price of $90.

A one to one at Wimbledon it is not; however, video tutorials showing Serena in action have now become available at Masterclass.com, a site built for those who wish to hone their own personal skills from sports to acting.

The site provides a comprehensive learning plan for players of all abilities, with 10 lessons covering everything from basic groundstrokes to the serve. As the holder of 19 Grand Slam Singles titles and an incredible 128mph serve, suffice to say there are few people more equipped to teach these essential skills.

Serena has joined the ranks of actor Dustin Hoffman, writer James Hoffman and photographer Annie Leibovitz to take time out from her busy schedule to teach her peers. And a busy schedule it is indeed – the star is now preparing for the French Open after pulling out of the Italian Open with an elbow injury. Defending her title in Rome, the 33-year-old was set to take on fellow American Christina McHale, but made the executive decision to keep herself in good health.

She said: “We have to make the right decisions for the future, not for now. You know I hate, hate quitting, and this isn’t quitting; it’s just making a good decision.” She added that she wanted enough time to heal and practice for the French Open, which is currently taking place at Roland Garros until 7th June.

Serena was not the only star to preserve her strength for France. World #3 Andy Murray also pulled out of the Italian Open recently, citing fatigue. He told his 3 million Twitter followers that he was fatigued after playing 10 matches in 12 days.

Let’s hope that both Murray and Williams are back to their best for the French Open this month – in the meantime, we’ll be signing up to the Masterclass to see if we can serve like Serena.
