Abstract:
1. An elliptical exercise machine comprising: a flame; a main drive link having a proximal and a distal end; a crank mechanism, said crank mechanism rotating said distal end of said main drive link through a continuous circular path; a footskate mounted to said main drive link via a foot track and capable of reciprocating on said main drive link wherein the combination of said reciprocating motion of said footskate on said main drive link and said rotational motion of said distal end of said main drive link moves said footskate through a generally elliptical path; and an adjustment arm rotating about a first axis of rotation and connected to said footskate, said first axis of rotation being moveable while said exercise machine is in motion; wherein, when said first axis of rotation is moved, the distance of said reciprocation is altered which in turn alters a horizontal dimension of said elliptical path without correspondingly altering a vertical dimension of said elliptical path.
