ABSTRACT:
An improved walking exercise apparatus includes a main frame, a positive drive means, a reverse drive means and two suspension bars. The main frame consists of two side upright supports and a base. The positive drive means consists of two drive chain wheels disposed at both ends of one side upright support, chains being partially engaging the circumferential rims of the drive chain wheels respectively and the chains being linked by rigid connecting elements. The reverse drive means consists of two drive chain wheels disposed at both ends of the other side upright support, chains being partially engaging the circumferential rims of the drive chain wheels respectively and the chains being linked by rigid connecting elements in a cross configuration. The suspension bars are pivotally disposed at the inner sides of the side upright supports near their upper ends and are coaxially secured with the upper drive chain wheels of the side upright supports respectively to allow pivotal swinging movement. The suspension bars respectively have a foot rest at a bottom end thereof.
