Abstract
An upper body exercise apparatus includes a spring positioned in a housing interior area. First and second cables have respective first ends operatively coupled to the spring and respective second ends extending away from the housing. Respective movements of the first and second cables away from the housing cause the spring to move toward a biased configuration. The exercise apparatus includes a transmission configured such that an outward movement of the first cable in the absence of an outward movement of the second cable causes all of the springs resistance to be transmitted to the first cable, an outward movement of the second cable in the absence of movement of the first cable causes all of the spring's resistance to be transmitted to the second cable, and an outward movement by both cables causes the spring's resistance to be distributed equally between the first and second cables.
