PayandPack Power Ball 3.5 accessory

3.5-Inch Power Ball for Grip Training

This 3.5-inch diameter spherical grip tool is built for climbers, ninja-warrior athletes and anyone targeting forearm, finger and biceps strength. The open-hand design lets muscles and tendons sit ergonomically while you train. A stainless-steel hanger hook and reinforced nylon webbing are included for immediate setup.

Upgrade from Fixed Bars and Standard Handles

Unlike a fixed pull-up bar or cylindrical handle, the ball forces an open-hand position that recruits stabiliser muscles throughout the forearm. The jump is worth it when your routine demands rotating between pull-up, chin-up and biceps-pull grips without re-gripping the strap. Buyers who need a second ball for two-arm hangs or who want a larger 4-inch diameter for very large hands should look elsewhere.

Sustained Hangs and Repeated Transitions

During long sessions the seamless surface maintains consistent friction without hot spots, and the webbing distributes load evenly across the hook. Sanding the surface first lets you tune roughness for chalk-free or chalk-heavy preferences. The seven-foot height limit and recommended cushion pad keep repeated drops controlled rather than jarring.
