Abstract
An exercise device including one or more weight stacks moveably supported on a frame. Each weight stack includes one or more weight plates that may be selectively engaged by way of a dial arrangement operably coupled with the weight stack. The dial arrangement is connected with a selection member that extends through a selection aperture in the weight plates. Each selection aperture defines a unique contour with at least one engaging surface, such as a tab. The selection member has corresponding protrusions adapted to engage the engaging surface of the weight plate. Each dial arrangement may be configured so that the weight stack may only be actuated when the selection member is properly positioned so that the protrusions properly engage the engaging surfaces. By adjusting the dial setting, the selection member is rotated so that one or more of the various protrusions engage associated engaging surfaces in order to engage some combination of weight plates. Upon actuation (i.e., exercise), the selected weights are engaged and moved when the selection member is properly orientated.
