A split (commonly referred to as splits or the splits) is a physical position in which the legs are in line with each other and extended in opposite directions. Splits are commonly performed in various athletic activities, including dance, figure skating, gymnastics, contortionism, synchronized swimming, cheerleading and yoga as exercise, where a front split is named Hanumanasana and a side split is named Samakonasana. A person who has assumed a split position is said to be "in a split" or "doing the splits".
When executing a split, the lines defined by the inner thighs of the legs form an angle of approximately 180 degrees. This large angle significantly stretches, and thus demonstrates excellent flexibility of, the hamstring and iliopsoas muscles. Consequently, splits are often used as a stretching exercise to warm up and enhance the flexibility of leg muscles. A split that goes beyond 180° is called an oversplit.
