Claim:
1. An exercise device which comprises: a. a frame; b. a first lever having a first end and a second end with said first end being pivotally attached to said frame for rotation about a first axis relative thereto; a second lever having a first end and a second end with said first end being pivotally attached to said frame for rotation about a second axis relative thereto; c. a connecting rod having a first end and a second end with said first end being pivotally attached to said first lever about a third axis relative thereto, and said second end being pivotally attached to said second lever about a fourth axis relative thereto; a first arm having a first end and a second end with said first end being pivotally attached to said frame about a fifth axis relative thereto; d. a second arm having a first end and a second end with said first end being pivotally attached to said second end of said second lever about a sixth axis relative thereto, and said second end being pivotally attached to said second end of said first arm about a seventh axis relative thereto; whereby rotation of said first lever causes an upward movement of said second arm relative to said frame; and e. a slide assembly to selectively vary the distance between said fourth axis and said second axis.
