ABSTRACT:
A balanced dumbell-shape striking type exercise device is mounted for adjustable balanced rotation about a support. Adjustment of rotatability is provided by a pair of springs on the support to apply rotation resisting force to the dumbell; by changing compression of the springs resistance to rotation is correspondingly varied. Handles on the support enable the exercise device to be hand-held or the support may be attached to a mounting bracket which holds one or more such exercise devices.
