Weights and measures
Because weightlifting is an international sport, the metric system is used. Weight is measured in kilograms and measurements are done in millimeters or meters. One kilogram equals 2.2046 pounds.
The competition platform measures 4 meters by 4 meters (13 feet by 13 feet). It is made of wood and may be covered with a non-slippery material.
The bar weighs 20 kilograms, is 2200 milimeters long and 28 milimeters in diameter. The bar for women weighs 15 kilograms, is 2010 milimeters long and 25 milimeters in diameter.
The discs or bumper plates are covered with rubber. Bumper plates are red (25 kg), blue (20 kg), yellow (15 kg) and white (10 kg). Discs lighter than 10 kg may be made purely of metal.
Collars secure the weights on the bar. Each collar weighs 2.5 kg. The bar must be loaded with the largest discs toward the middle of the bar and the lighter discs in descending order toward the outside.
A one piece lifting suit shall be worn by all lifters. It cannot cover the elbows or knees, and it is usually made of lycra material.
Low or high topped shoes may be used. The mid-soles are made out of wood or rubber, and the uppers out of leather or suede.
A lifter may use a weightlifting belt. It may not exceed 120 millimeters, or 4.5 inches, in width.
