Abstract: 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.

Abstract: An upright mechanical arm is pivoted to a freestanding base for grasping by a player to simulate an arm-wrestling contest. The arm is power-driven in a given direction by a hydraulic jack. The force applied by the jack is adjustable. Switches detect grasping of the mechanical arm by the player and positioning of the player's elbow on an elbow pad. Such switches are interconnected with control of the hydraulic jack to cut off the supply of hydraulic liquid automatically. Bells and buzzers can be provided to indicate when the game has been "won" or "lost" by the player.
