ABSTRACT:
A multi-functional physical exercise apparatus includes a small hollow cylinder, a large hollow cylinder, a confining device and a coiled spring. The large hollow cylinder is sleeved movably on a normal position on the small hollow cylinder. The confining device confines the large hollow cylinder on the small hollow cylinder. The coiled spring is secured to one of the small and large hollow cylinders at one end thereof and is confined at a predetermined position in the other one of the small and large hollow cylinders at the other end of the coiled spring. Accordingly, in a case where the large hollow cylinder is rotated relative to the small hollow cylinder or is moved toward the outer end of the small hollow cylinder, releasing one of the small and large hollow cylinders causes the large hollow cylinder to return to the normal position on the small hollow cylinder.
