Abstract
A weight changing system includes a body carrying a plurality of pins which body is fixedly aligned with respect to the top of a weight stack so that the pins carried by the body are aligned with corresponding openings in the weights. The pins are selectively driven from a retracted position in which the pin is not inserted in its corresponding weight opening to an extended position in which the pin is inserted in the corresponding opening. Upon receipt of a signal representative of momentary muscular failure of the user, the pin controllers retract the pin supporting the stack of weights being lifted and insert a higher pin in the opening in its weight to automatically decrease the weight being lifted. Multiple momentary muscular failure points are achievable with this system.
