Swimming styles, also known as strokes, are techniques used to move through water. The four main styles are freestyle, breaststroke, backstroke, and butterfly. Each style has its own unique movements and breathing patterns, allowing swimmers to compete in various events. Freestyle is the fastest and most popular stroke, while breaststroke is characterized by a frog-like kick. Backstroke is performed on the back, and butterfly involves a simultaneous arm movement and a dolphin kick. Swimmers often choose a style based on their strengths and preferences, making each competition diverse and exciting.
