What are common swimming strokes?


assistant
The most common swimming strokes include the four strokes used in competition: freestyle (sometimes referred to as "the crawl"), breast stroke, back stroke and butterfly. In addition, some people swim using a side stroke or a doggy paddle (which looks a lot like the stroke dogs use when swimming).
