Abstract
A collapsible ladder for use primarily for athletic training and the like has a plurality of spaced-apart, substantially rigid rungs secured with collapsible connectors to a plurality of spaced-apart, substantially rigid spacers extending therebetween. In one disclosed embodiment, the collapsible connectors are strips of flexible material extending between the rungs and spacers. Another disclosed embodiment has a second set of rungs aligned substantially parallel to the plurality of spaced-apart rungs along a common central set of spacers. The collapsible connectors allow the ladder to be quickly and easily transitioned between an extended, operational position, and a collapsed, storage position.
