Claim Text:
1. A device for providing exercise to a user, comprising: a frame, comprising a first and a second arm, a first end of each arm meeting in fixed angular relationship at a vertex and a second end of each arm extending away from the vertex; a lever arm, having a first and a second end, the first end constrained to rotate about a pin located near the vertex; a resistance arrangement, configured to convert rotation by a user of a first rotational assembly about an axis on the second end of the first arm into rotation of a second rotational assembly about an axis on the second end of the lever arm, which is converted into rotation of a third rotational assembly about an axis on the second end of the second arm, with the rotation of the third rotational assembly being resisted by a resistive element, the resistance arrangement providing a substantially constant resistance against the rotation of the first rotational assembly; wherein the frame comprises a first and a second member, the members being mirror images of each other and set in spaced apart relationship to each other; wherein the resistive element comprises a gas spring, arranged in the frame between the first arms of the first and second frame members, the gas spring having an arm that is compressible into a cylinder; and wherein the first rotational assembly comprises:
