Butterfly Stroke |
It is a swimming stroke in which the arms are plunged together forward in large circular movements. It is performed facedown, in which both arms are thrust out at the sides at the same time, brought forward out of the water, and then down through the water in a circular motion, while using an up-and-down leg movement. |
