ABSTRACT:
A multiexercise weight lifting machine which features in its most basic embodiments a gearbox capable of converting the torque input through a first axle from a source of resistance (such as a weight stack) into a greater torque output at a second axle to which is connected a user interface (such as a handle); which gearbox is slidably mounted on a linear member such that the gearbox can be moved to different positions along the length of the linear member to allow different types of exercises. In its preferred embodiments it also features means for reversing the torque output at the second axle and user interface. Its numerous functions and benefits may also be supplemented by addition of a weight bench, provision of means for changing the gear ratio of the gearbox, and other features.
