ABSTRACT:
Flexible cables extend upward from a carriage slidable along an upright column, then over guide pulleys and downward to a barbell. Latch mechanism interconnects the carriage with the column so as to support the weight of the barbell. The latch mechanism is releasable by actuation of an electromagnet to permit normal exercise by raising and lowering the barbell which causes corresponding lowering and raising of the carriage along the column.
