A few simple tips to improve your game and your pleasure on the court !
When you train with your opponent before the start of a match, try to see what is its weak point to play on it during the game.
If you have to lob your opponent, try to lob on his backhand side. He will thus be forced to bypass the ball and play an eventual smatch with more difficulties.
It is sometimes better to serve on the weak point of your opponent to take an advantage. It will be more easy to control your serve in order to finish the point in a constructive way !
Many players relax their vigilance after winning the first set easily. Stay in the game ! Remember that a match is never finished until the last point was not played.
Enjoy the recovery time between points to recover physically. Concentrate on your breathing, slow it down. A slow inspiration and a slow expiration will help you recover and keep all your lucidity for the following point.
