An elliptical exercise apparatus, comprising: (a) a main frame having a base; (b) first and second supporting members, each supporting member having a first end portion and a second end portion, the first end portions of the supporting members respectively being coupled to the main frame to rotate about a first axis around a first closed path, the second end portions of the supporting members being able to align at an aligned axis; (c) first and second pedals respectively coupled to the first and second supporting members; (d) a guider frame pivotally connected to the main frame at a pivot axis so as to be movable between an in-use position and a storage position, the guider frame respectively having a track for supporting the second end portion of the respective supporting member both in the in-use position and in the storage position, the second end portion of the respective supporting member being movable on the track between a first end point, and a second end point (P2, P3) of a reciprocating path while the guider frame is at the use position, the first end point being closer to the first axis than the second end point (P2, P3), a minimal periphery being defined by the rotating path of the second end portions when aligned on the aligned axis as the guider frame is rotated about the pivot axis, a second periphery being defined by the rotating path of the second end point (P2, P3) about the pivot axis, the minimal periphery and the second periphery intersecting at a first intersection point (P5, P5b) wherein the pivot axis of the guider frame is located at a first height relative to the base and characterized in that the pivot axis is higher than the first and second end points (P1, P2) of the reciprocating path, so that an arc of the second periphery between the first intersection point and the second end point (P2, P3) at the use position has a first lifting angle which is greater than sixty degrees.
