Abstract
Abstract A stationary exercising device which promotes cardiovascular exercise yet minimizes impact to critical joints, particularly the ankles and knees. A frame supports a linkage assembly having at least one linkage member with a camming surface. The linkage assembly is in turn connected to a coupling assembly attached to the frame. Structure is included which permits each foot of the user to move the linkage assembly in such a manner as to generate a preferred closed path movement for the feet and a preferred arcuate path for the hands minimizing unnecessary stress in the joints yet permitting a cardiovascular workout of both lower and upper body muscle groups.
