Claim:
A variable exercise apparatus comprising: a frame structure member having a guide member mounted thereon, said guide member having a varying contour, a user support member mounted on said frame structure member, said user support member including a seat, a user engagement member comprising an engagement support structure extending in the forward and backward directions, said engagement support structure pivotally mounted at a backward end to said frame structure member such that said engagement support structure pivots in the generally horizontal plane, an assembly support member coupled to the forward end of said engagement support structure, said assembly support member movable in the general upward and downward directions, with the upper end of said assembly support member having an engagement assembly mounted thereon, and a coupling member for coupling the lower end of said assembly support member to said guide member of said frame structure member, a base, said guide member mounted to said base, a support member mounted to said base and extending in the general upward direction, said user support member being mounted to said support member, whereby a user may sit on the seat of the user support member and engage the engagement assembly with the general thigh portion of the leg such that the pivoting movement of the engagement support structure around the support member of the frame structure member produces movement of the assembly support member along the contour of the guide member which produces an upward and downward movement of the engagement assembly.
