ABSTRACT:
A pair of axially telescoping members each mount plural springs within their interior. The telescoping members are held together in coaxial alignment by a rod. A spring loaded indexing mechanism about the rod allows racheting between preferential angular orientations of the first member relative to the second member. At these angular orientations various ones of the plural springs within the bore of each telescoping sleeve may be placed in coaxial position. By the number of springs which are selectively coaxially positioned the device accords a varying resistance to compression which is useful for exercizing muscles.
