In freestyle swimming, 50% of the propulsion in the water comes from the kicking movements. Therefore, swimmers need to constantly practice various kicking movements both on land and in the water. I also incorporate underwater training into my training (for example, swimming underwater using only kicking movements, with or without fins, or simulating freestyle kicking movements underwater (done while holding your breath with your arms straight against the side of the pool). #freestyle #freestyle

An underwater shot shows João de Lucca demonstrating his freestyle swimming technique. Watch his arm extension and how it helps his speed and efficiency in the water. A great demonstration for improving swimming! #swimming #freestyle #armextension #sports #exercise | GoSwim.tv
