Olympic barbells are specialized weightlifting bars used in competitive sports like weightlifting and powerlifting. They typically weigh 20 kilograms (44 pounds) for men and 15 kilograms (33 pounds) for women. These bars are designed to hold standard Olympic weight plates, which have a 2-inch diameter hole for fitting onto the bar. The construction of Olympic barbells includes high-strength steel, allowing them to withstand heavy loads. They feature a rotating sleeve design, which helps reduce torque on the wrists during lifts. Olympic barbells are essential for athletes training for events in the Olympic Games and other strength competitions.
