Arguably the most glamorous Olympic sport, beach volleyball has grown from being played by a handful of families in Santa Monica, California in the 1920s to now being the sport of choice for 800 million people throughout the world.
Matt Chilton, BBC Sport
"It is easy to just talk about the outfits, but if you watch beach volleyball for 10 minutes you will realise how incredible these athletes are. The speed and strength the men and women show to play on sand in the baking heat is a real eye-opener. Team GB face a huge challenge as whoever they play, in whatever round, will be ranked way higher than them. In the women's competition, Americans Misty May-Treanor and Kerry Walsh are going for the gold medal Olympic hat-trick, which has never happened before. Brazilians Emanuel and Alison are expected to compete with Americans Philip Dalhausser and Todd Rogers for the top spot in the men's."
International tournaments have been played in the mountains, deserts, town squares and indoors. At London 2012 it will be staged at Horse Guards Parade, normally reserved for the Queen's birthday celebrations.
Beach volleyball has been as well known for its competitors' attire as its elite sport status, but the outfit worn by Denise Lewis when she won heptathlon gold in 2000 was actually smaller than the costumes worn by female beach volleyballers.
As hosts of the 2012 Olympics, Great Britain are guaranteed a place for one male and one female beach volleyball team.
The other 15 places in each competition will be decided at qualifying events, with the United States, Brazil and China set to be the leading medal contenders.
Why is it good for you?
Beach volleyball is an excellent way to stay fit as exercise on sand can be up to 30% more strenuous than exercise on concrete surfaces.
It also helps improve balance, endurance and lower body muscle, with an hour's play burning approximately 526 calories.
As it is harder to gain height springing up from sand, beach volleyball relies more on technique than size and strength, making it an inclusive sport. Players also touch the ball more often than in indoor volleyball as there are just two players per team.
As beach volleyball is played in pairs, it is an excellent way to develop communication skills and learn to work effectively with other people. Clubs also offer a variety of social events beyond simply taking part in the sport.
Beach volleyball is an exciting, competitive team game that forces you to think tactically.

The rules at London 2012
A point is gained when the ball lands in the opposition side of the court.
Great Olympic moment
In front of an ecstatic home crowd of 10,000, Natalie Cook and Kerri Pottharst won gold for Australia at Sydney 2000. It was an epic final, with the Australian underdogs fighting back in both sets to beat Adriana Behar and Shelda Bede of Brazil 12-11 12-10.
Matches are the best of three sets, with 21 points required to win a set, and 15 in a potential third and deciding set. To win a set, a minimum two-point advantage must be held over the opposition duo.
In the case of a 20-20 tie, play is continued until one team gains a two-point lead.
When hitting the ball, players must make a clean, quick hit. Teams can hit the ball three times in their half of the court but a player cannot hit the ball twice in a row. The winner of the last point gets to serve, with players in a team alternating the serve if they retain possession after winning another point.
In beach volleyball, the court is 16m long and 8m wide. The court is divided in the middle by a 1m-high net that strung between two posts so that it is 2.43m off the ground for men and 2.24m off the ground for women.

Beach volleyball began to gain popularity throughout the United States during the 1930s and the first official two-man tournament took place in 1947.
Did you know?
About 5,000 tonnes of sand will be imported from a quarry in Surrey for the tournament, which takes place only five minutes from the Cabinet War Rooms where Winston Churchill orchestrated victory in the Second World War
The first beach volleyball circuit involving hundreds of players and five California beaches began in the 1950s. Signs of the sport's continuing popularity came in the 1960s when Marilyn Monroe and John F Kennedy watched a tournament, and the Beatles even tried to play while in California.
Beach volleyball had to wait until 1996 to make its Olympic debut in the Atlanta Games, with the USA and Brazil dominating the medal count since its introduction.
The first international beach volleyball tour in 1990 involved three tournaments, 40 athletes and three countries. In 2011, the season consisted of 30 tournaments (14 for men, 16 for women), with total prize money of £4.8m.
It is not true that the women are obliged to wear bikinis - they have always been able to choose from a one or two-piece uniform, and
in London will have the option of wearing shorts and sleeved tops.
