powerlifting bar
A powerlifting bar is a specialized piece of strength training equipment designed specifically for competitive powerlifting and serious strength training. This precision-engineered bar, typically weighing 20kg (44lbs), features distinct characteristics that set it apart from standard barbells. The bar's shaft diameter usually measures 29mm, providing the optimal balance between grip security and performance. Most powerlifting bars are constructed from high-grade steel, often featuring a tensile strength rating between 190,000 to 220,000 PSI, ensuring durability and resistance to permanent deformation under heavy loads. The knurling pattern on powerlifting bars is typically more aggressive than standard bars, offering enhanced grip security during heavy lifts. Key features include dual knurl marks for both powerlifting and Olympic lifting hand positions, and specialized knurling patterns in the center for squat positioning. The bar's sleeves are designed with precision bushings or bearings, allowing for minimal rotation during lifts, which is crucial for maintaining stability during heavy squats, deadlifts, and bench presses. The bar's whip (flex) is deliberately minimized to ensure maximum force transfer and stability during max-effort lifts, making it ideal for the three primary powerlifting movements.
