In the early days, what we today call a power rack was referred to as a “Power Lockout Machine.” All semantics aside, it was an apt name since it was used –you guessed it– for strengthening lockouts and heavy partial portions of specific lifts. This idea has a great deal of merit, and few people use it today to the extent that they could especially given that racks are much more common and available. Above, Harvey McCune, middle-heavyweight lifting champion of El Paso, Texas works on improving his arm lock for the jerk. This idea was pioneered by Bob Peoples and also used a great deal by his friend Paul Anderson.
