An exercise device providing a fore and aft horizontal component of striding motion that is dynamically user-defined, while providing a vertical component of the motion that is maintained on a predetermined vertically reciprocating path in some embodiments. The exercise device guides the user's foot in a pseudo-elliptical stride path, while providing a dynamically variable stride length that allows the user to move with a natural stride length. The exercise device allows tall and short users to extend or curtail the stride length to match their natural stride lengths. The length of the reciprocating path is dynamically adjusted during the exercise operation without equipment adjustments by changes in the length of the stride input by the user at a pair of foot engagement pads disposed on laterally spaced apart foot support members. 1a frame;right and left elongate stride members supported on the frame and each including first and second opposed ends and a foot engagement pad positioned therebetween;right and left crank arms operatively associated with the frame and configured to rotate about a crank axis, the right and left crank arms including right and left supports, respectively; andright and left engagement features adjacent the respective first ends of the right and left elongate stride members, the right and left engagement features riding on the right and left supports, respectively..
