Swim strokes.

There are many different types of strokes for swimming, these are just to name a few:

• The Breast-stroke*;
  A swimming style that's swam on the breast, it's usually the most popular stroke used. In most swim classes, this is one of the first strokes beginners learn. But in swim racing it is known as one of the most difficult strokes requiring more endurance compared to other strokes.
  
  
• The Trudgen*;
  A swimming stroke, also known as the racing stroke, or the East Indian stroke, named after the English swimmer John Trudgen. This stroke has been developed into the front crawl.
  
  
• The Butterfly*;
  A swimming stroke also swum on the breast, while both arms move simultaneously. Also known as the dolphin kick to some, the butterfly stroke, unlike most other strokes, is not easily swam, and requires experience and technique.
  
  
• The Front crawl*;
  Also known as The Australian Crawl, is usually regarded as the fastest swimming style developed. Unlike the (above) strokes, the front crawl is not actually regulated by F.I.N.A*, but it's almost universally swum in freestyle competitions.

• The Sidestroke*;
  A stroke, named so because the swimmer lies on their side. Often used as a lifesaving technique, and for long distance swimming, the sidestroke allows the swimmer great endurance, without as much work needed. A swimmer tired of exercising one side can just turn over and use the other, the change of action helping the limbs recover.
  
  
  
  

• The Freestyle*;
  One of the official swimming competitions, although it is technically not a style.Though there are very few regulations about the way freestyle has to be swum, most swimmers choose to swim front crawl during freestyle, as this style is generally the fastest.
  
  
• The Backstroke*;
  Also known as the back crawl, is one of the four regulated swimming styles, and the only regulated style swum on the back. This has the advantage of easy breathing, but the disadvantage of not seeing where the swimmer is heading to. The Backstroke is also the only competition swimming style that starts in the water.
  
  
• The Doggy Paddle*;
  A simple swimming stroke, it's done by the swimmer lying on their chest and moving their hands and legs alternately in a way that resembles how dogs swim. It's usually the first swimming technique children use when learning how to swim.
