Here’s one you probably havent seen before: The Super Neck Developer from World Sporting Goods, circa the mid-1970’s. This device did not use a weight stack or any kind of weight at all, a friction brake provided the resistance. As such, given the angles, and the fact that gravity was no longer a limitation, this provided some interesting possibilities, as you can see. This machine was marketed to football coaches for the purpose of having their players strengthen their necks to lower the frequency and severity of concussions. Amazingly, over four decades later, neck machines are seldom found in many college weight rooms.
