Butterfly stroke

The butterfly, (fly for short) is a swimming stroke swum on the breast, with the arms moving synchronously. The butterfly kick was developed separately, and is also known as the Dolphin. While other styles like breaststroke, front crawl, or backstroke can be swum easily even for beginners, the butterfly requires a very good technique to be feasible. Most students consider it the most difficult style. It is also the newest swimming style swum on competitions, first swum around 1934.
