Abstract: A means and method for automatically selecting an amount of weight to be connected to a cable system in a fitness machine. When a dial is rotated to select a weight, a connected computer receives the rotational position information, operates a program to determine the amount of each weight to attach to the cable system and actuates solenoids accordingly to attach the weight to the cable by inserting pins fully into weight stacks to connect weights to a rod connected to a cable. The computer also displays the selected weight on the dial. When the new weight is selected, one or more retracting solenoids draw any inserted pins partially out before any new pins are fully inserted to connect the weights to the rod. This ensures that the system is cleared before attaching any weights to the cable.
