Abstract
An exercise machine has a base with an upright member secured thereto. A pair of lever arms are rotatably positioned on the upright member and rotate from a first position to a second position. A gas cylinder assembly is mechanically associated with the upright member and connected to the lever arms by a chain means. The gas cylinder assembly provides resistance to movement of the lever arms from the first toward the second position. A purchase assembly is mechanically associated with the frame and connected to the lever arms by a cable means. The purchase assembly includes a block and tackle to provide a mechanical advantage for moving the lever arms from the first position toward the second position. A line from the block and tackle is connected to one of several possible moveable elements such that operation of the moveable element results in movement of the lever arms.
