IronMind Hub

Introduced by IronMind in 1990, the Hub allows you to build and test your pinch grip in the great tradition of Karl Norberg hauling up an old-style York 45-lb. plate by its hub with three 10-lb. plates on it.  Hook up the IronMind Hub to a loading pin with a carabiner and you can go as light to heavy as you'd like, whether you use Olympic plates or standard plates.

The IronMind Hub and 15" Olympic loading pin and carabiner are available from the IronMind store, which has a complete selection of grip strength and hand health tools.
Please contact if you have any questions.

IronMind Hub Contest Rules
  1.   The IronMind Hub must be an authentic IronMind Enterprises Hub. It cannot have been modified or tampered with in any way. The Hub must be wiped clean before each attempt.
  2.   Ordinary chalk (magnesium carbonate) may be used on the lifting hand, but nothing else is permitted (liquid chalk, for example, is specifically disallowed).
  3.   Weight is hung from the Hub using an IronMind 15" Olympic loading pin and carabiner. The total weight for the world record attempt includes the equipment and the weights, that is, the Hub, loading pin, carabiner, and plates; weight for the Hub + pin + carabiner = 5 lb. / 2.26 kg. The plates must either be calibrated or can be weighed on a proven scale.
  4.   The lifter starts the lift with all 5 fingertips of the lifting hand touching the plate at the base of the Hub.  It is permissible that the fingers rotate somewhat from this position during the course of the lift, but holding the Hub as if grabbing a doorknob is not allowed. The Hub must remain approximately parallel to the ground. Other than incidental contact, the hand or Hub must not touch the body before the lift is completed—dragging the hand or Hub up the leg is cause for an immediate "No lift."
  5.   The lifter must fully straighten up (back erect, legs and hips locked out); once standing straight, the lifter must maintain control of the lift for 1 second before getting a down signal from the referee, and must then return the weight to the ground. Contact must be maintained between the lifter's hand and the Hub until the weight is resting on the floor. The referee then indicates whether the lift was passed or not. 
  6.   In contest situations,  the lifter is given 1 minute to complete the lift after his/her name is called; during that minute, there is no limit to how many times the lifter may try to complete the lift.
