ABSTRACT:
A stretchable exercising device is integrally molded from elastic material and has two separate strap sections each with a handle loop. The strap sections being connected to only one other strap section at a generally central, integral joinder which forms a single continuous uninterrupted unitary connection. The other strap section has a greater resistance to stretching than any of the remaining two, due to an increased cross-sectional area. The loop of the other strap section is large enough to receive two feet in a side-by-side disposition. The remaining two strap sections may also be of mutually different resistance to the stretching force.
