Beach volleyball is one of those sports that can be an exciting game to play and watch, or, can just be about some friends getting together to have a great time. It’s really easy, and all you need is sand, a net and a group of people, of any age or fitness level, who want to have fun.

Beach volleyball can be played with as few as two people on each team, making a total of four people. However, if you are less skilled and experienced in the game, it will be easier to play with a larger team. The more players you have, the less ground each person will be responsible(负责)for covering and the more time they will have to recover in between shots. If you only have a few players, each of you will get quite a workout running for the ball after each volley. If you are looking for that relaxing, fun, low-key experience, choose larger teams.

Beach volleyball is similar(相似)to regular volleyball in its rules. However, even experienced volleyball players do not realize how much more difficult it is to run and jump on sand. Since it is harder to move quickly on sand than a hard ground, play will be much slower than regular volleyball on a playground. When a player trains for beach volleyball, he will focus(专注)on building lower body strength as well as upper body. While he needs to be able to hit the ball with a great deal of power and accuracy(准确性), strengthening his legs is extremely important.

Whether you are in it for the competition, or just to have a great time with your friends, beach volleyball can be very exciting and fun. You may even start out with friends and fall in love with the sport.
