Get a total body workout with just one lifting bar by performing squats, back rows, chest and shoulder presses, deadlifts, shrugs and more. ProsourceFit barbells are uniquely designed for both men and women (larger bar is for men) with multiple purposes in mind, from standard squats to Olympic lifts to workouts. Moderate knurl has dual marks to guide your hand position for Olympic or power lifts and a smooth center without knurl is easy on hands and back. The 160k Psi steel bars are both finished with black phosphate finish for durability, rust-protection and a polished look. Chrome sleeves (12.5” on women s bars, 16.25” on men s) with bearings provide a smooth rotation for easy movement of the bar to allow for heavy exercises like cleans and snatches. Standard bumper plates fit these barbells so you can continue to increase and adjust the weight for increased strength and stamina. Limited lifetime warranty is included so you can purchase confidently.
