Surfing is an extreme sport in which the surfer is carried along by a breaking wave towards the shore. The surfer lies or sits on the board to wait for the wave. As the wave approaches, the surfer lies on the board and paddles with both arms as the wave approaches from behind. Once the wave begins to carry the surfer forward, the surfer stands up and proceeds to ride the wave. The basic idea is to position the surfboard so it is just ahead of the break (whitewash) of the wave. Surfing is a game of speed in which the surfer can enjoy the excitement of battling against the wave.
