Abstract
A first end of a lever pivots about a fixed axis as a second end is raised and lowered by the user. A carriage is disposed on the lever and is designed to travel the length of the lever between the first and second ends. A belt is coupled to a weight and to the carriage through a series of pulleys. The lever is shaped so that the weight neither raises nor lowers as the carriage travels from one end of the lever to the other. The distance that the weight travels in response to movement of the second end is thus proportional to the position of the carriage on the lever. By moving the carriage to numerous positions between the first and second ends of the lever, the torque needed to lift the weight and the distance by which the weight moves may be varied correspondingly in numerous increments over a very large range. A number of different user interfaces may be coupled to the lever for creating an equal number of different weight training machines.
