Which men's artistic gymnastics event uses hanging rings?

The men’s artistic gymnastics event that uses hanging rings is the still rings event. Two rings hang independently from straps attached to a rigid frame, and the gymnast must control both the apparatus and his body throughout the routine.

Still-rings routines emphasize upper-body strength, stability and static holds. Gymnasts perform swings, strength elements, handstands and skills such as the iron cross before finishing with a dismount. Because the rings can move freely, keeping them still during strength positions is itself an important part of the challenge.

The event is traditionally associated with men’s artistic gymnastics because of its exceptional upper-body demands. “Rings” is the common short name, while “still rings” distinguishes the apparatus from flying rings, which are a different historical form. The other options belong to separate men’s events: the horizontal bar, parallel bars and pommel horse.
