The rings, also known as still rings (in contrast to flying rings), is an artistic gymnastics apparatus and the event that uses it. It is traditionally used only by male gymnasts, due to its extreme upper body strength requirements. Gymnasts often wear ring grips while performing. The apparatus consists of two rings that hang freely from a rigid metal frame. Each ring is supported by a strap, which in turn connects to a steel cable that is suspended from the metal frame. The gymnast, who grips one ring with each hand, must control the movement of the rings and his or her body movements at all times. (Source: Wikipedia.org, CC BY-SA)
