A multi-function exerciser includes a main frame. Two first universal joint units and two second universal joint units are respectively provided at two sides of the main frame. Two action units are pivotally connected to the first and second universal joint units. The two axes of the first and second universal joint units at the same side are at the same level and perpendicular to each other. Thus, the user can swing forward and rearward as well as left and right when standing on the footrests of the two action units for a forward split and a side split. Besides, because the two axes are at the same level and perpendicular to each other, the user can stand with one foot and lift another foot to do an oval turning for getting strong muscles in the legs.
