ABSTRACT:
A exercise machine has a pulley for user's flexibility to choose between training at the selected weight plates' full weight, or at the half weight when the pulley is engaged. A latching switch is used for easy selection of going between the full weight and half weight mode. A counter weight block is attached to an end of the cable, to keep the tension of the cable when the exercise machine is used in the full weight mode.
