Abstract
An apparatus for exercising muscles of the fingers, hands, wrists and forearms, includes a shaft having a longitudinal axis, a flexible cord connected to the shaft and a weight member suspended from the flexible cord, so that a user can grasp and rotate the shaft about the longitudinal axis while positioning the shaft substantially horizontally to wrap and unwrap the cord around the shaft and thereby raise and lower the weight member. The apparatus also includes a hollow outer cylinder shorter than the shaft mounted substantially coaxially over the shaft and having a cord opening through which the cord passes, first and second outer cylinder end walls having central bores and first and second tubular end flanges extending outwardly from the outer cylinder and over the shaft, the first end wall being structurally connected to the outer cylinder, a first set screw in the first end flange for tightening to cause the outer cylinder to rotate in unison with the shaft so that the outer surface of the outer cylinder gathers and releases the cord, for increasing the distance between the longitudinal axis of rotation and the surface about which the cord is gathered to increase rotational re…
