IronMind Hub

The IronMind Hub is a pinch-grip training tool – a 2-7/8” diameter steel disc with a textured crinkle finish, machined to mimic the center hub of a classic deep-dish 45 lb steel plate. It’s a modern take on an old-school Strongman warm-up: lifting a plate off the floor by pinching only its center hub, the way “The Mighty Norseman” Karl Norberg used to test his grip. The Hub attaches to a loading pin (12” standard or 15” Olympic, sold separately) via carabiner, letting you load barbell plates to progressively overload the pinch.

It’s become a staple at grip competitions worldwide and part of IronMind’s Crushed-to-Dust! Challenge. Published difficulty standards give lifters a benchmark: 30 lb is “alright,” 50 lb is “excellent,” and 80 lb and up is “world class” – current hub-pinch world records sit at 44.80 kg (98.96 lb) for men and 26.36 kg (58.11 lb) for women. Reviewers and demo videos consistently treat it as a legitimate strength test rather than a novelty: one training-log video shows it humbling an experienced grip athlete with “big beefy hands,” and a Rogue Fitness customer calls the build “overbuilt.” The smooth crinkle finish gets slick with sweat, so most lifters chalk up before using it.
