An exercise apparatus comprising a frame, a pivot arm mounted on the frame, a resistance mechanism, preferably an elastomeric torsion member, and a positioning element which allows the pivot arm to be pivotally adjusted with respect to the frame, independent of the resistance element, so as to vary the neutral position of the pivot arm. The preferred embodiment may also comprise a shaft mounted to the frame for conveying torque to the elastomeric torsion member and a support arm mounted to the frame to oppose rotation of the elastomeric torsion member about the shaft. In one embodiment, the exercise apparatus takes the form of a weight bench. In a second embodiment, the exercise apparatus is a home gym.
