ABSTRACT:
An exercise apparatus includes a lower bracket which clamps onto the bottom of a door and bolts which are threaded into the tower bracket and which jack the bracket upwardly against the door to prevent motion of the door. A tension spring connected to the sower bracket is connected to a cable which is guided by pulleys which are mounted on an upper bracket. The upper bracket is clamped on the top of the door. The cable is connected to a handle which enables a user to pull on the cable against the resisting force provided by the spring thereby exercising the user's muscles.
