<p>A forearm exercising device having a support frame and a grip secured to one end of a shaft rotatably secured in said support frame and a crank arm secured on the opposite end of said shaft. A cylinder such as a shock absorber operably secured to the shaft controls the rate of movement of the shaft and the grip or crank arm to which the user applies his arm regardless of the force exerted thereon. An upper arm support and restraint member is adjustably secured to align the medial axis of the forearm with the axis of rotation of the shaft which the user is gripping such that movement is controlled as the user moves his hand through supination and pronation. A forearm support platform is secured such that the hand and wrist extend beyond the edge of the platform when gripping the crank arm to restrain forearm movement as the hand moves through palmarflexion and dorsiflexion in moving the crank arm at a controlled rate of speed.</p> |
