Abstract
Abstract An exercise apparatus having a collapsible frame that simulates walking, running and climbing depending upon where the foot is positioned along the elongate pedal. The user is able to maintain a standing posture while elongate pedals supporting each foot move through an exercise cycle having a different mode for each foot position that includes translating and non-parallel angular motion generated by a linkage mechanism.
