Swimming is a fun but energy-consuming sport. There are four swimming styles, namely freestyle, breaststroke, backstroke, and butterfly stroke. When you do freestyle, cross your arms like paddles and splash water with legs moving alternatively. If you do breaststroke, your arms and legs take turns to move like frogs. Backstroke is like freestyle, but you turn your body upside down. Relatively speaking, it's the easiest one. Butterfly stroke is to flap the water like butterfly's wings with your arms. All in all, swimming is really fun. You must try all these styles.
