Failing grip strength is an athlete's indication of fatigue when training. Harbinger's Big Grip Bar Grips help you build muscular endurance in a way that will improve functional grip strength.
How? Big Grips Bar Grips convert barbells, pull-up bars & cable attachments into "thick bars". Thick bar training activates more muscles when lifting, building bigger, stronger arms and upper body faster. Weightlifters, Powerlifters and Strongmen have used thick bar training for decades because it produces noticeable results in less time than standard training.
Made from a proprietary high-density compound, Harbinger Big Grip Bar Grips attach to the bar like a clamp and maintain their shape --even when lifting extreme loads. Big Grip Bar Grips are also easy to clean and transport so you can use at home and at the gym, and everywhere you lift.
