Swimming is the movement of the body through water using arms and legs. People can swim in the sea, swimming pools, rivers and lakes. People swim for exercise, for fun, and as a sport. There are several styles of swimming, known as "strokes", including: front crawl, breaststroke, freestyle, butterfly, and backstroke.
