A compact exercise apparatus for use in performing a plurality of exercises having a resistive load is disclosed. A frame structure is provided for supporting the load and a mechanism is employed for moving the load from a first to a second position. A linkage arrangement is disposed between the moving mechanism and the load and includes a plurality of interconnected pivotably operably lever arms. The linkage arrangement is in multiple mounting communication with the moving mechanism at one of the interconnected lever arms. This combination of structure enables the proper biomechanical and kinesiological movement of each of the exercises and permits moving the load from the first position to the second position. In a preferred embodiment, a frame structure supports a movable weight stack and an exercise bar is utilized to move the load from a first to a second position. A lever arm linkage arrangement is disposed between the exercise bar and the weight stack and includes a plurality of interconnected lever arms operating through a corresponding plurality of pivot points. Each of the lever arms is adapted for multiple mounting communication with the exercise bar for enabling the proper biomechanical and kinesiological movement of each of the exercises and for moving the weight stack from said first to said second position.
