Tennis is an interesting sport. It expends energy a lot, so tennis is also a tired sport. When you play this interesting exercise, you need at least two players and 264 square metre wide place. It's like badminton, but tennis just let the ball bounce once in our own place, or you will lose points. You have two chances to serve the ball, if the ball touch net or out of the service area, You will lose the point, too. One player's game is different from two player, because the place will be wider.
If you want to win the champion,then you and your partner need a good teamwork.
