Patent ID: 7044897

Claim:
An exercise apparatus having an exercise station that is selectively moved by a user and having first and second resistance assemblies that selectively provide resistance to movement of the exercise station, the exercise apparatus comprising: a frame; an exercise station; a first resistance assembly including a first weight stack; a second resistance assembly including a second weight stack; and a coupling system configured to couple the first resistance assembly to an exercise station and to couple the second resistance assembly to the first resistance assembly, such that movement of the exercise station requires movement of at least a portion from each of: (i) the first resistance assembly, and (ii) the second resistance assembly, wherein the coupling system comprises: (i) a first attachment system selectively coupling the exercise station to the first weight stack; and (ii) a second attachment system selectively coupling the second weight stack to the first weight stack, such that movement of the first weight stack requires movement of the second weight stack, wherein the first attachment system comprises: (i) a first cable and pulley system coupled to the frame; (ii) a first selector rod coupled to the first cable and pulley system, the first selector rod configured to be extended within the first weight stack and having a plurality of apertures configured to receive a first pin therein; and (iii) a pin selectively mounted in the first selector rod when the first selector rod is extended within the weight stack, and wherein the second attachment system comprises: (i) a first coupling member selectively coupled to the first selector rod, the member configured to receive the first selector rod through an aperture therein; (ii) a second cable and pulley system coupled to the first coupling member and the frame; (iii) a second selector rod coupled to the second cable and pulley system, the second selector rod configured to be extended within the second weight stack and having a plurality of apertures configured to receive a second pin therein; and (iv) a second pin selectively mounted in the second selector rod when the second selector rod is extended within the second weight stack.
