Breaststroke is a swimming style where someone floats in the water and moves their arms and legs to propel themselves forward. It is called breaststroke because the movements look like a person is mimicking the way a bird flaps its wings or a person's arms when hugging someone tightly. Breaststroke is one of the most popular swimming styles, often taught to beginners, and is used in both recreational and competitive swimming.
