Title: Selective lift elliptical exercise apparatus

Abstract: The present invention relates to a standup exercise apparatus that simulates walking, jogging and climbing with arm exercise. More particularly, the present invention relates to an exercise machine having separately supported pedals for the feet and arm exercise coordinated with the motion of the feet. Cross trainers guide the feet along a generally elliptical shaped curve to simulate the motions of jogging and climbing. Existing machines often produce user problems such as excessive foot articulation. The present invention is an improved elliptical exercise machine capable of extended exercise with fewer user problems. Further, the cross trainer is adjustable to vary the motion of the elliptical stride from walking to climbing. The intermediate portion of a foot support member is guided by a guide member and drives a crank linkage on one end with pedal on the other end. The resulting pedal motion has less severe pedal angles than a simple crank cross trainer. Handles are coupled to the foot support member for coordinated arm exercise.
