ABSTRACT:
A quadrilateral exercise and training device includes a plurality of longitudinally extending channel members mounted on cross frame members so as to define elongated slots in which foot-supporting members and hand-engaging members can reciprocate. A control system interconnecting the foot-supporting members and hand-engaging members includes a main flat synchronizing belt interconnecting the foot-supporting members and hand-engaging members to establish desired coordination between the respective members, a safety belt interconnecting the foot-supporting members and a drive belt associated with each foot-supporting member which operatively engage a pair of drive shafts having a braking system and an optical transducer for converting rotation of one of the drive shafts to a digitized informational readout for use by an operator.
