Abstract
Abstract A skipping exercise device is disclosed. The device comprises a rectangular frame formed from a lightweight synthetic resinous material to define two long sides and two short sides. The two long sides are each hinged at points equidistant from a first short side located from such first short side between one-ninth and one-third the length of the long sides. An abrasion resistant sleeve is positioned over such first short side and, optionally, a rotatable handle is positioned over the second short side.
