Iron rings

Iron rings are heavy metal rings used in martial arts for various training purposes. Metal rings have a long history of being used in Yau Kung Mun, Hung Gar, and other styles for weight training, to harden the muscle, skin, or bone, or strengthen the arms and fists.

Types of rings
Many different types of rings are available. The Chi Sau Ring is used for conditioning the body in many stances, and exercises. Four-inch-diameter (4 in) Chi Sau Rings weigh 600 g; 5 in iron rings weigh 800 g. Some iron rings are sold in sets, such as two small and two large rings. Some rings are made of other metals such as steel or brass, and rattan rings are also used for exercise.

Use in martial arts
Chinese forms training is done to improve the mind and body. To get the most out of your forms training, martial arts practitioner and writer Stefan Verstappen suggests that forms training be done with “brass or steel rings ...around the wrists and ankles to add weight during the performance of the form.” Verstappen states that “[s]pecial wrist and ankle weights can help in the development of muscles, and endurance. Light dumb bells can also be substituted." He warns that people doing training should "...be careful not to perform the movements too quickly since the weights tend to make you overextend your techniques which can cause injury to the joints.” Other ways of enhancing the value of forms training include training outdoors in varied conditions and using varying speeds. Ying Ching Kuen and external forms of Yau Kung Mun are practised with iron rings to build strength, power, and endurance.

The southern Chinese kung fu style of Hung Gar is "hard, strong style" that uses "rooted stances such as the horse stance (mabu)". Hung Gar practitioners use "...sand bags to strengthen grip, as well as iron rings in strengthening arms and tight fists." Hung Gar is derived from the Shaolin Temple kung fu system developed during the Ching dynasty. Hung Gar training uses "...prolonged stance training and many isometric breathing exercises. To do fist training, students wear iron rings, weighing from 2-4 lbs on their arms. "The force of the student's strike causes the rings to slide down the arms smashing into the back of the hands, reminding the students to hold a "tight fist.""
