Freestyle swimming is a popular stroke used in competitive swimming and recreational activities. It involves a face-down position in the water, with alternating arm movements and a flutter kick. Swimmers typically breathe by turning their heads to the side, allowing for a continuous and efficient motion. This stroke is often the fastest in swimming competitions, such as the Olympics and World Championships. Freestyle is also a common choice for triathlons and open water events. Swimmers can improve their technique through drills and practice, focusing on body position, breathing, and stroke efficiency.
