1. An elliptical exercise apparatus, comprising:
(a) a stationary main frame having a base adapted to rest on a ground surface; (b) a crank assembly including a crank unit mounted to the main frame at a first axis; (c) 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 coupled to the crank assembly to rotate about the first axis and around a first closed path, the second end portions of the supporting members being able to align at an aligned axis, and a minimal periphery defined by the first axis and an aligned radius which is the distance between the first axis and the aligned axis; (d) a guider frame pivotally connected to the main frame at a pivot axis to be movable relative to the main frame between a use position and a storage position wherein the first axis of the crank assembly is stationary when the guider frame is movable between the use and storage positions, the guider frame respectively having a track for supporting the second end portion of the respective supporting member at both the use and storage positions, the second end portion of the respective supporting member movable on the track within first and second reciprocating end points of a reciprocating path while the guider frame is at the use position, and a second periphery being defined by the pivot axis and a second radius which is the distance between the pivot axis and the second reciprocating end point, the minimal periphery and the second periphery intersected at a first intersection point located above the track of the guider frame wherein the pivot axis of the guider frame is located at a first height relative to the base and an arc of the second periphery between the first intersection point and the second reciprocating end point at the use position has a first lifting angle which is greater than sixty degrees; and (e) first and second pedals respectively coupled to the first and second supporting members. |
