A portable exercising device having a pair of laterally spaced lever arms whose forward ends are pivotally attached to a base frame assembly. Each lever arm has a resistance cylinder whose bottom end is pivotally attached to the base frame assembly and whose top end is pivotally attached adjacent to the rear end of the lever arms. Each lever arm has a foot pedal plate mounted thereon. An action-reaction structure causes one of the lever arms to pivot upwardly in response to the other lever arm member being pivoted downwardly and also vice versa. A pair of telescoping pole members have their bottom ends attached to the action-reaction structure and they are capable of a forward and rearward pivoting action which is coordinated with the up and down pivotal motion of the lever arm members.

A portable exercising device comprising: a base frame assembly having a longitudinal axis extending from its forward end to its rearward end; a pair of laterally spaced lever arm members each of which is substantially oriented in parallel alignment with the longitudinal axis of said base frame assembly; means for pivotally securing the forward ends of said lever arm members to said base frame assembly adjacent its forward ends; a foot pedal plate mounted on each of said lever arms adjacent their rearward ends; a pair of resistance cylinders each of which has a top end and a bottom end; first attachment means for pivotally attaching the top end of said respective resistance cylliner to said respective lever arm members; second attachment means for pivotally attaching the bottom ends of said resistance cylinders to said base frame assembly; action-reaction means for causing one of said lever arm members to pivot upwardly in response to said other lever arm member being pivoted downwardly and also vice versa; and wherein said action-reaction means comprises a pair of laterally spaced pivot plate members, said pivot plate members being vertically oriented and each of which has its lower end pivotally attached to said base frame assembly.
