Sitting cross-legged is a method of sitting on the floor to rest, stretch, or pause. In some cultures, it is customary to sit cross-legged on the floor to eat. Sitting cross-legged is also common in grade school where it is frequently referred to as sitting criss-cross applesauce. Sitting cross-legged is considered “active rest,” as it requires more muscle use than sitting in a chair and can improve stability and flexibility.
