ABSTRACT:
The disclosed invention relates to the integration of a resistance selection of selectorized weight stacks with a range of motion (ROM) selection of ROM elements adapted to engage a user and transmit a lifting force to an in-line selectorized weight stack. It involves replacing the weight selector rod of prior selectorized weight stacks with a flexible connector (FC). The FC operates in-line to respective ROM elements and is guided from below a selectorized weight stack and above, at a particular weight stack travel, for vertical oscillatory movement through a vertical opening extending through the central portion of a weight stack. An engaging member is provided to engage a selected weight plate at a selected point along a FC's length, whereby, providing an integrated range of motion selection of FC in-line ROM elements with a resistance selection.
