Butterfly

This interactive illustration captures four moments in the butterfly stroke. In the butterfly, the arms move together through the water, and the feet pump together in what is known as the dolphin kick. Swimming the butterfly is tiring, so few swimmers use it except during races. However, the butterfly’s effort does translate into speed, and it is almost as fast as the crawl stroke. In this diagram, the swimmer is moving to the right.
