Abstract: An apparatus for augmenting exercise of body muscle(s) comprising one or more articles of close-fitting wearing apparel employing one or more removable elongate resistance members, loosely enclosed in passageways along a portion of the length of the apparel, which resistance members releasably anchored at one end to a fixed-in-place member such as a belt or a shoulder harness and attached at the distal end to the extremity of an arm or leg, the apparatus being devised so as to increase the energy required by a user to flex his arms or legs over the energy level necessary without the resistance of the elongate resistance members.
