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 resulting from improper stride length or excessive ankle 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. A foot support member is guided by a guide on one end and drives a control linkage on the other end. The resulting pedal motion is independently adjustable in stride length and ellipse orientation during operation. Handles are provided for coordinated arm exercise that adjusts with stride adjustment.

1. An exercise machine comprising;a framework configured to be supported on the floor; a crank means rotatably connected to said framework, said crank means projecting outwardly therefrom on both sides thereof; a pair of guide means, said guide means operably associated with said framework; a pair of roller means, said roller means operably associated with said crank means; a foot support member for each foot, said foot support member having a portion supported by said roller means and operably associated with said guide means to move with a generally back and forth orbital movement; a control linkage, said control linkage having a plurality of control links positioned rearward said exercise machine, operably associated with said crank means and said foot support member; a pedal means operably associated with said foot support member to move along an elongate curve path having a predetermined curve length; a means for adjustment, said means for adjustment operably associated with said control linkage and said foot support member to cause a change in the relationship between said control links when desired by the operator; said pedal means configured to move relative to said framework when the foot of the operator is rotating said crank means whereby said predetermined curve length can be changed.
