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 linkage assembly interposed between each foot support and the base. Each linkage assembly accommodates a pivotal movement of a corresponding foot support relative to the base between forward and rearward positions and accommodates a 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 movement of the foot supports between forward and rearward positions or between upward and downward positions so that movement of one foot support relative to the base effects a corresponding movement of the other foot support relative to the base.
