Pinch Hub Grip Trainer

The Pinch Hub Grip Trainer, sold on Amazon and manufactured by Great Call Athletics as the “Power Pinch,” is a hub-style pinch grip trainer aimed at rock climbers, arm wrestlers, and grip-sport athletes. It’s built from powder-coated steel with a three-inch textured “crinkle finish” gripping surface designed to work the thumb and fingers together, the same motion trained by classic hub lifts. It has no built-in weight of its own – lifters attach it to a standard loading pin via a heavy-duty carabiner (both sold separately) and load weight plates to set resistance. Owners on GymRadar describe its gripping depth as comparable to a Marcy LA hub (deeper, and therefore easier, than a York milled hub), and use it as a stepping stone toward heavier hub lifts. It’s a budget alternative to dedicated grip-sport brands like IronMind, with reviewers consistently surprised by the build quality for the price – though independent editorial and video coverage of this specific product is still thin.
