olympic bar
The Olympic bar is a precision-engineered piece of strength training equipment that serves as the cornerstone of weightlifting and powerlifting exercises. Measuring 7.2 feet (2.2 meters) in length and weighing 44-45 pounds (20 kg), this standardized barbell is designed to meet International Weightlifting Federation specifications. The bar features a knurled grip pattern that provides secure handling during various lifts, with dual knurl marks indicating proper hand placement for different exercises. The shaft diameter of 28-29mm ensures optimal grip comfort while maintaining structural integrity for heavy loads. Olympic bars are constructed from high-grade steel, typically featuring a tensile strength rating between 150,000-190,000 PSI, allowing them to support substantial weights without permanent deformation. The bar's sleeve ends rotate on precision bearings, enabling smooth movement during dynamic lifts and reducing torque transfer to the lifter's hands. Most quality Olympic bars can accommodate up to 1,500 pounds of weight, making them suitable for both professional competition and intense training sessions.
