ABSTRACT:
A rotatively manipulable arm, hand and wrist exercise device comprising at least two grippable handle elements surmounted upon a longitudinally extended shaft having means at one end thereof to retain said handles in abutting relationship. Said shaft further projects beyond the handle assembly, and is threaded along a portion of its projecting or distal end whereby to conformably accommodate thereon an axially adjustable housing. By manually adjusting said housing, friction-producing means are caused to engage and sufficiently compress the handle elements whereby to create torsional resistance opposing the relative counter rotation of said handles.
