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. Elliptical cross trainers guide the feet
along a generally elliptical shaped curve to simulate the motions of
jogging and climbing. Existing elliptical cross trainers often use
excessive pedal articulation which can overwork the ankle to achieve a
longer stride. The present invention is an improved elliptical exercise
machine capable of extended exercise with less pedal articulation that is
more ankle friendly. One end of a foot support member is guided by a
guide link for back and forth movement while the other end is guided by a
drive link with cam guide to drive an alternator and flywheel. The
resulting pedal motion-is foot friendly. Stride length can be adjusted.
Handles are coordinated with the foot support members for arm exercise.
