Isn't That Backwards?

Why kick on your back when you swim on your front? Swimmers can often get into bad habits. Some of those habits can be fixed by practicing the correct body movements in a different way. For instance, breaststrokers may get in the habit of dropping their knees toward the bottom of the pool when trying to swim faster. To help your muscles remember not to do that, practice breaststroke kicks on your back where you cannot drop your knees. Then, flip over and see how it feels.

Flutter kicking on your back in a streamline position helps keep your body in an elongated position, the best position to be in while swimming, and a position that swimmers may forget to emphasize when tired. You have to stay long while on your back in order to float.
