An exercising device with side-by-side external weights that are movable relative to each other so as to permit the device to assume a circular curvature in encircling relation about a limb of the user, this assumed curvature being used to advantage to position the device in overlying relation to a selected specific muscle for development of that muscle rather than for merely gross limb motion exercises as now results from a wrist, ankle or waist location.
