Overview
A butterfly is a swimming stroke that’s performed mainly with the shoulders, chest, and legs. It involves both arms moving symmetrically and a kick that looks like a butterfly.The butterfly was developed by several swimmers and is known as a type of freestyle. It originated in the 1920s when swimmers were trying to swim out of the water while swimming the breaststroke.The butterfly is a challenging swimming style. It does not obey the law of inertia, which means that it requires more energy. Almost all of the propulsion occurs in the down kicks. The first down kick is when the hands push under the body, while the second down kick is when the arms return to the water. The down kick is the most difficult part of the butterfly, so it’s important to master the basics of this technique.
