ABSTRACT:
A variable ratio multi-purpose exercise device for simultaneous use by two opponents in which the opponents transmit force and resistance to each other through a block and pulley combination which is so adjustable as to balance out strength difference between the two. The device utilizes identical first and second hand lines each of which runs through a plurality of pulleys and has at its termini a snap hook. Each of the hand lines passes through the block of a main pulley fixed to an external support structure and then through the blocks of secondary pulleys located on both sides of the main pulley. The secondary pulleys are each attached to a handle bail which, in turn, is adjustably attached to the handle. In operation, opponents may perform movements which exercise the same muscle groups in each of them or one opponent may elect to exercise a different muscle group than that selected for exercise by the other.
