It is traditionally used only by male gymnasts due to its extreme upper body strength requirements.
The apparatus consists of two rings that hang freely from a rigid metal frame.
Each ring is supported by a strap, which connects to a steel cable suspended from the metal frame.
[3] One of the most widely recognized skills performed on the rings is the Iron Cross, which is executed by extending both arms straight out from the sides of the body while suspended mid-air for at least two seconds.
On rings, gymnasts will also take deductions for having bent arms while performing nearly all elements or using the straps/cables to support or balance themselves.
