ABSTRACT:
An arm, wrist and shoulder exercising device includes a pair of elongated spindles connected to each other through an angularly adjustable locking member. A hand grip is rotatably mounted about each spindle and a frictional clutch is provided with may be adjusted to vary the force required to rotate each hand grip with respect to the spindle. The locking member includes a disc at one end of each spindle, and the discs are secured to each other by a threaded fastener extending through the centers of the discs. Radial teeth extending from the centers of the discs interlock to prevent rotation of the discs with respect to each other in order to fix the angle between the hand grips. The longitudinal axes of the spindles substantially intersect at the threaded fastener.
