    Abstract: A rotational forearm exercise apparatus including a pair of bar members rotationally connected endwise together at a midpoint. Each of the pair of bar members is rotational relative the other against action of a compressive spring member disposed around a threaded bolt member interior to at least one of the pair of bar members. Rotation of each of the pair of bar members in a first direction relative one another forces travel of a threaded washer along the length of the threaded bolt member toward the midpoint whereby the spring member is compressed. Rotation of each of the pair of bar members in a second direction relative one another forces travel of the washer along the length of the threaded bolt member away from the midpoint whereby the spring member is decompressed. Force required to rotate the pair of bar members is thus increasable and decreasable.
