Backstroke is a swimming style performed on the back, where swimmers alternate their arms in a windmill motion while kicking their legs. This technique allows for a streamlined position in the water, making it efficient for speed and endurance. Swimmers breathe freely since their face is above the water, which is a key advantage of this stroke. In competitive swimming, backstroke is one of the four main strokes, alongside freestyle, breaststroke, and butterfly. Races are typically held in a pool, and swimmers start from the water, pushing off the wall to begin. Proper technique is essential for maximizing speed and minimizing drag.
