ABSTRACT:
An exercise device includes a frame defining a longitudinal axis. A foot link includes a rearward portion that is constrained to move in an orbital path approximately parallel to the longitudinal axis and a forward portion that reciprocally engages the guide track. A swing arm is a pivotally connected to the frame, the swing arm having an upper portion extending above the pivotal connection and a lower portion disposed below the pivotal connection. An engagement mechanism having a first portion coupled to the lower portion and a second portion coupled to the forward portion of the foot link, such that a rearward force applied to the upper portion will produce a force on the forward portion having a downward component. An arm enabling/disabling mechanism is positioned on the elongate swing arm below the pivotal connection. The arm enabling/disabling mechanism can be effectuated by a user without the user interrupting exercise.
