Abstract

A training ladder formed of a plurality of substantially rigid polygon-shaped segments detachably secured together with segment connectors extending therebetween. The sides of each segment are substantially the same to allow the segment connector to join any sides between two adjacent segments. Accordingly, the path through the ladder can be varied. In one disclosed embodiment, the segments are octagon shaped and pivotally secured to the segment connectors, thereby allowing the ladder to collapse into a stack when not in use and allowing some of the segments to extend substantially vertically, thereby defining a hurdle or other possible vertical structure.
