The disclosed apparatus provides a base supporting at one end an upstanding mast pivotally mounting a boom in the upper portion of the mast to extend over the base. A bench to support a user is supported by the base spacedly thereabove and below the boom. A handle assembly is pivotally carried by the boom end extending over the base to depend spacedly above the base. A hydraulic cylinder communicates between the boom and the base to resist pivotal motion of the boom responsive to exercise motion of the handle assembly by a user supported on the bench. A resistance assembly provides spaced grips carried by a pull shaft for longitudinal motion toward and away from the bench end distal from the mast. The pull shaft end proximate the mast communicates by cable supported on pulleys to the boom end distal from the handle assembly so that the boom resists motion of the resistance assembly grips responsive to exercise motion thereof by a user supported on the bench. A self-contained electrically powered hydraulic system operates the hydraulic cylinder and provides an adjustment mechanism to determine resistive force of the boom and switch structure to determine operation of the system.

An apparatus for exercising, comprising: an elongated base having opposed ends and a bench attached thereto spacedly above the base; an elongate upright mast having an upper end and a lower end, said mast being rigidly attached to the base; a longitudinal boom assembly having opposed first and second ends, the boom assembly being pivotally attached intermediate its ends to the mast, adjacent the upper end of the mast, and the boom assembly being capable of pivotable movement about an axis perpendicular to the elongate axis of the mast; adjustable pressure means having a first end pivotally attached to the boom intermediate the boom first end and its attachment to the mast and a second end pivotally attached to the base, the pressure means being adapted to apply a continuous force on the boom; handle means attached to the first end of the boom assembly, the handle means adapted to be grasped by a user for imparting pivotal movement to the boom assembly; a longitudinal pull shaft carrier pivotally mounted to a carrier support rigidly attached to the base, the pull shaft carrier defining a medial channel therethrough; a pull shaft with opposed first and second ends slidably carried in the medial channel defined in the pull shaft carrier; an arm assembly pivotally attached to the base and to the second end of the pull shaft to impart reciprocating movement to the shaft responsive to pivotal motion of the arm assembly; and cable means attached between the first end of the pull shaft and the second end of the boom to pivot the boom assembly when the pull shaft is moved away from the mast.
