ABSTRACT:
Apparatus for exercising rotary neck muscles having a compound cam for transmitting forces from the neck muscles through a movement arm and to a resistance weight to lift the weight. A pin mounted to move with the movement arm is receivable in one of a plurality of apertures in the cam to rotate the cam with the movement arm. The cam transmits drive to lift the resistance weight by a cam follower engageable with either of a pair of cam surfaces formed on the periphery of the cam depending upon the direction of rotation of the cam. Adjustable stop mechanisms are also disclosed for limiting the range of angular movement of the movement arm.
