1. An exercising machine for a user comprising:
- a support frame;
a bar pivotally connected to the frame and defining a bar pivot;
exercising paraphernalia;
interconnecting mechanism connecting said bar to said exercising paraphernalia whereby user movement of the paraphernalia produces pivoting of said bar;
a spring member engaging said bar and resisting pivotal movement of said bar through resisted deflection of the spring member, said spring member inherently providing increased resistance as the spring member is increasingly deflected; and
a coupling arrangement forming at least a part of said interconnecting mechanism, said coupling arrangement including a pivot arm in sliding abutment with said bar and pivoted by said user movement to produce a changing lever advantage as the bar is pivoted to thereby counter the increasing resistance of the spring member.

Abstract
An exercising machine wherein a cable pull is resisted by spring deflection. The cable is connected to a lift arm that is pivotally fixed and carries a lift roller. The lift roller abuts a pivotally mounted bar and urges pivotal movement of the bar opposed by a spring member. The connection of the cable to the pivotal lift arm, the position of the lift roller relative to the lift arm pivot, the engagement of the roller with the pivotal bar and the engagement of the spring member with the pivotal bar all involving lever advantages that can be manipulated to achieve varying shapes of resistance of the cable pull as felt by the user.

14. An exercising machine comprising:
-
a cable and cable guide arrangement for cable pull by a user desiring to exercise, the cable pull by the user defining a first direction of cable pull;
a pivotal bar and a compressible spring member engageable with the bar and inherently providing increased resistance as compression of the spring increases;
a coupling arrangement coupling the spring member to the cable, said coupling arrangement including a pivot arm pivoted by the cable pull and as pivoted slidably engaging the bar to urge the bar in a direction opposite the spring member, said slidable engagement changing the lever advantage to counter the increasing resistance of the spring member. - View Dependent Claims (15, 16, 17, 18)
