The famous swimming technique employed at the Olympics is the freestyle stroke, also known as the front crawl. This style is recognized for its efficiency and speed, where athletes alternate their arms in a windmill motion while kicking their legs behind them. The freestyle allows swimmers to take deep breaths and maintain a streamlined position, contributing to faster travel across the water. It is commonly seen in various events, including the 100m, 200m, and long-distance races, showcasing elite athleticism and technique.
