An exercise apparatus is disclosed for exercising a user thereof. The apparatus includes a frame and an elongate beam having a first and a second end. The beam is pivotally secured to the frame about a first pivotal axis disposed between the first and the second end of the beam. A user operated arrangement having a first and a second extremity is connected to the beam between the first end of the beam and the first pivotal axis. The arrangement is such that in use of the apparatus, when the user is exercising, the user exerts a variable force through the user operated arrangement, the variable force being transmitted to the beam for pivoting the beam about the first pivotal axis. Weights are pivotally secured to the frame such that in use of the apparatus, movement of the weights from a first to a second disposition thereof is permitted. A linkage extends from a second end of the beam to the weights such that in use of the apparatus during the beginning of an exercise, the weights are disposed in the first disposition thereof so that a minimal force is required to maintain the weights from movement thereof to the second disposition. However, during further exercising movement of the user, a further force greater than the minimal force is required in order to counteract a tendency for the weights to move from the first to the second disposition thereof so that the variable force is required by the user during use of the apparatus.
