Freestyle

The swimmer maintains a strong and steady flutter kick. The stroke begins with the swimmer's arm extending forward at about shoulder width, then coming back across the body to the hip. During recovery the arm is brought back toward the head, keeping the elbow raised above the body. Strokes alternate between arms. The swimmer exhales underwater and takes a breath when needed.
