Title: Arm wrestling unit

Abstract: An "arm wrestling" exercise device comprising; a helical coiled spring with a hand extension and adjustably mounted in a sleeve between a pair of brackets on a base providing for elbow engagement and arm deflection of the spring to a "down" position. The sleeve is angularly adjustable to accommodate the user's arm length and the spring is axially adjustable within its sleeve retainer to vary the number of active coils and thereby the stiffness and force required to deflect the spring. Such adjustment together with a series of calibrated coiled springs provide for continuous adjustment of stiffness from minimum to maximum.
