Abstract
A machine for exercising and/or testing the lumbar muscles including a movement arm mounted for rotational movement about a generally horizontal axis against a resistance provided by a weight stack. Movement of the movement arm is transmitted to the weight stack by means of a transmission including a cam fixed to the movement arm, a pulley belt fixed to the periphery of the cam and trained about one or more pulleys mounted with respect to the stationary frame of the machine. The pulley belt is connected to an actuating lever connected to the weight stack pin to drive the same. One of the pulleys is mounted for movement towards and away from the pulley belt to increase or decrease tension in the pulley belt to thus control the drive between the movement arm and the weight stack.
