Abstract: A multi-use exercise device having an elastic, flexible line with a length sufficient for an operator to use the line as a jump rope. A pair of rigid handles are attached to free ends of the lines. The handles are attachable to form a longitudinal composite handle. A pair of rings are carried on free ends of the handle and are sized to be received on the line when the line is folded onto itself with the ring slipped over the fold and retaining the line in the folded position to thereby shorten the length or modify the shape of the line.
