Abstract: An elastic exercise device which provides varying resistance to exercise to enable a user to adjust the resistance depending on the strength of the muscles being exercised. The resistance to exercise is varied by selectively adjusting and securing the length of a resistance member. The present invention is directed to a flexible host member carrying a resistance member. The resistance member has an adjustment section which extends along at least length of the flexible host member and is accessible for adjustment. A securing member is attached to the adjustment section, whereby the length of the resistance member is secured alter being adjusted. The length of the resistance member is shortened by accessing the adjustment section of the resistance member, drawing a loop portion of the adjustment section, wrapping the loop portion around or against the flexible member, wrapping the securing member around the flexible member and then fastening the securing member.

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.
