Claim:
1. A resistance assembly, comprising: a housing that has a first attachment assembly proximate to a first end of the housing and a second attachment assembly proximate to a second end of the housing; and wherein the second attachment assembly is configured to be engaged to a structure; a first resilient member for providing a first resistive force; a second resilient member for providing a second resistive force; and an adjustment assembly which is selectively engageable with the first resilient member or both of the first and second resilient members; and when the adjustment assembly is engaged with only the first resilient member, the resistance assembly will provide the first resistive force to a pulling motion on the first attachment assembly; and when the adjustment assembly is engaged with both of the first and second resilient members; the resistance assembly will provide the first and second resistive forces to the pulling motion on the first attachment assembly; wherein the adjustment assembly includes a selector rod that selectively engages the adjustment assembly with the first resilient member or both of the first and second resilient members.
