Abstract
A method and apparatus for providing variable resistance in connection with exercise equipment uses vertically oriented weight plates that rare in a side-by-side arrangement and are selected by selectors in a selector assembly. A set of actuators are controlled by a computer processor and force the selectors into positions that engage and disengage with a corresponding set of weights. The computer is connected to a user interface that accepts input from a user and instructs the computer to adjust the amount of weight using the actuators and the corresponding selectors. The computer is also in communication with sensors that indicate whether the weights have been lifted successfully and automatically select a lower weight when the weights are not lifted successfully.
