Shark fin

The shark exercise is similar to the swordfish. The only difference is that the back arm is raised like a shark's fin with each breath (see picture). As soon as the face is back in the water, the arm returns to its original position. This exercise aims to train the coordination between the crawl stroke and breathing. In crawl swimming, the sideways breath begins as soon as the arm leaves the water backwards and ends when the arm re-enters the water at the front.
