A multi-function exercise machine is composed of a first base (20), a pair of swing arms (10), two reversing elements, an extension rod (30) and a second base (40). The swing arms (10) are pivotally mounted on the first base (20) and automatically returned to their original position by the reversing elements after they are pulled or pushed, thereby exercising a user's muscles. The extension rod (30) attached to the first base (20) is retractable and selectively secured to the second base laterally or vertically to make the exercise machine capable of being used with a variety of different exercises.
