ABSTRACT:
A cross-training exercise apparatus includes a base, a pair of foot supports pivotally and slidably joined to the base by way of a three-member linkage arrangement interposed between each foot support and the base. Each three-member linkage arrangement accommodates a pivotal movement of a corresponding foot support relative to the base between forward and rearward positions and accommodates a sliding movement of each foot support relative to the base between raised and lowered positions. The exercise apparatus also includes a pair of cable and pulley arrangements which are associated with the base and joined between the foot supports for coordinating the pivotal and sliding movement of the foot supports between forward and rearward positions or between upward and downward positions so that pivotal or sliding movement of one foot support relative to the base effects a corresponding pivotal or sliding movement of the other foot support relative to the base.
