in the 1992 IronMind catalog. IronMind promoted and further developed this idea in later catalogs. It first published a chart in 1995 highlighting how grip strength applies to activities and professions ranging from law enforcement to powerlifting and playing music, and expanded on it in subsequent catalogs. Two books written by grip-strength expert John Brookfield and published by IronMind – Mastery of Hand Strength, Revised Edition (2008) and The Grip Master's Manual (2002) – also expand upon these basic components of grip strength, which are now considered as widely accepted fact. Captains of Crush Grippers IronMind is known worldwide for its Captains of Crush line of hand grippers. These grippers, considered the "industry standard" in building grip strength, have become somewhat of a cult phenomenon and have amassed a worldwide following – one British strength enthusiast has written into his will that he would like to be buried with his Captains of Crush hand gripper. In 1991, IronMind began certifying people able to close the company's benchmark Captains of Crush No. 3 gripper; certification on the Captains of Crush No. 4 was added in 1998 and certification on the Captains of Crush No. 3.5 was added in 2008. Only five people (Joe Kinney, Nathan Holle, David Morton, Tommy Heslep and Magnus Samuelsson) have been certified for closing the No. 4. Publications IronMind has published 18 books by established authors such as John McCallum, Ben Weider and David Webster. It has also developed and published books by such first-time authors as John Brookfield, Steve Jeck, Steve Justa, Brad Johnson and Brian Jones, many of whom have become authorities in their fields. Randall J. Strossen's first book, Super Squats: How to Gain 30 Pounds of Muscle in 6 Weeks (1989), was also the first product offered by IronMind. It presents the classic 20-rep squat routine, a routine best known for helping people bulk up in a short period of time. The book is currently in its eighteenth printing (in English) and has been translated into German. As a photographer and editor-in-chief for IronMind's quarterly journal MILO (launched in 1993), Strossen flies over 100,000 miles a year to cover strength-sport events around the world. MILO is the only American bodybuilding or weightlifting magazine to receive media accreditation to cover weightlifting at the 1996, 2000, 2004 and the 2008 Olympics. Arnold Sports Festival IronMind has been involved as a sponsor or an organizer of
