Exercise machine for near-elliptical arm movement

An exercise machine for a near-elliptical arm movement, comprising at least one set of manual arm-moving structure enabling an elliptical movement, at least one set of reciprocating pivot shaft structure enabling a linear or curved reciprocating movement or at least one set of restriction and control guide rail structure system enabling a reciprocating movement or at least one set of restriction and control guide wheel structure system enabling a reciprocating movement, at least one set of cycling pivot shaft structure enabling a circular movement, a linkage structure, a framework structure, wherein the manual arm-moving structure enabling the elliptical movement is pivotably connected to the cycling pivot shaft structure at one position thereof, and performs a full-cycle movement, and the manual arm-moving structure enabling the elliptical movement is pivotably connected to the reciprocating pivot shaft structure at another position or another portion thereof, or performs a linear or curved bidirectional reciprocating movement under restriction and control of the restriction and control guide rail structure system enabling a reciprocating movement or the restriction and control guide wheel structure system enabling a reciprocating movement;

• a handle structure is directly or indirectly provided on the manual arm-moving structure enabling the elliptical movement;
• the cycling pivot shaft structure is a pivot shaft structure arranged outside a crank structure enabling a full-cycle movement, or a crankshaft structure, or a pivot shaft structure arranged on an eccentric bearing outer ring structure.
