ABSTRACT:
An expander type exercising apparatus has an elongated stretchable elastic element consisting of one or more coil springs, elastic tubes and/or elastic strands. The elastic element is confined in the median portion of an elongated tube-like envelope the end portions of which are directly or indirectly secured to and extend beyond the respective ends of the elastic element. The end portions of the envelope have looped sections which constitute handles to be grasped by a person wishing to stretch the elastic element by way of the two end portions of the envelope. The sizes of the looped sections are adjustable to thus change the overall length of the apparatus. The envelope consists of filaments which are woven around the elastic element while the latter is maintained in stretched condition.
