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 for back and forth movement while the
other end is guided by an orbital link 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.
