(a) an interconnection of the upper leg members for synchronized out of phase pivoting about each respective upper pivot point,
(b) each of the lower leg members being separate and independent for autonomous pivoting of each of the lower leg members relative to each other about each respective lower pivot point, and
(c) a joint-pivot spatial correlation selected from at least one of:
(i) a location of the upper pivot axis configured to pass through or posterior to the hip region of an orthostatic forward facing suited user supported upon the foot supports with the foot supports horizontally and vertically aligned, and
(ii) a location of each of the lower pivot points configured to be respectively proximate to one of the knees of the orthostatic forward facing suited user supported upon the foot supports with the foot supports horizontally and vertically aligned.
2. The exercise device of claim 1 wherein the joint-pivot spatial correlation is a location of the upper pivot axis configured to pass through or posterior to the hip region of the orthostatic forward facing suited user supported upon the foot supports with the foot supports horizontally and vertically aligned.
3. The exercise device of claim 1 wherein the joint-pivot spatial correlation is a location of each of the lower pivot points configured to be respectively proximate to one of the knees of the orthostatic forward facing suited user supported upon the foot supports with the foot supports horizontally and vertically aligned.
4. The exercise device of claim 1 wherein the joint-pivot spatial correlation is both (i) a location of the upper pivot axis configured to pass through or posterior to the hip region of the orthostatic forward facing suited user supported upon the foot supports with the foot supports horizontally and vertically aligned, and (ii) a location of each of the lower pivot points configured to be respectively proximate to one of the knees of the orthostatic forward facing suited user supported upon the foot supports with the foot supports horizontally and vertically aligned.
5. The exercise device of claim 1 wherein each lower leg member communicates with a biased damping means for biased pivoting of each lower leg member about each respective lower pivot point towards a first direction and damped pivoting of each lower leg member about each respective lower pivot point in a second direction opposite the first direction.
6. The exercise device of claim 5 wherein a biasing force exerted by each of the biased damping means is adjustable.
7. The exercise device of claim 5 wherein a damping force exerted by the biased damping means is adjustable.
8. The exercise device of claim 6 wherein a damping force exerted by the biased damping means is adjustable.
9. The exercise device of claim 1 further comprising a control console attached to the frame proximate to the forward end of the frame.
10. The exercise device of claim 1 wherein (i) each upper leg member pivots about the respective upper pivot point and is coupled to the respective lower leg member which pivots about the respective lower pivot point, and (ii) each upper leg member pivots about the respective upper pivot point autonomously relative to pivoting of the respective lower leg member about the respective lower pivot point, whereby (iii) pivoting of each upper leg member about the respective upper pivot point effects pivoting of the respective lower pivot point about the upper pivot point without inducing pivoting of the respective lower leg member about the respective lower pivot point.
11. The exercise device of claim 1 wherein (i) each lower leg member pivots about the respective lower pivot point and is coupled to the respective upper leg member which pivots about the respective upper pivot point, and (ii) each lower leg member pivots about the respective lower pivot point autonomously relative to pivoting of the respective upper leg member about the respective upper pivot point, whereby (iii) pivoting of each lower leg member about the respective lower pivot point does not induce pivoting of the respective upper leg member about the respective upper pivot point.
12. The exercise device of claim 10 wherein each lower leg member pivots about the respective lower pivot point autonomously relative to pivoting of the respective upper leg member about the respective upper pivot point, whereby pivoting of each lower leg member about the respective lower pivot point does not induce pivoting of the respective upper leg member about the respective upper pivot point.
13. An exercise device having (-) a frame with a forward end and a rearward end wherein the frame is configured and arranged to accommodate user access onto the exercise device from the rearward end, (-) left and right leg linkages, each including (i) an upper leg member pivotally coupled to the frame for pivoting about an upper pivot point, with the upper pivot point of each leg linkage defining a point on a laterally extending upper pivot axis that passes through the upper pivot point of each leg linkage, and (ii) a lower leg member directly pivotally coupled to the upper leg member distal to the upper pivot point for pivoting about a lower pivot point, and (-) a foot support attached to each lower leg member distal to each respective lower pivot point, characterized by an ergonomically synergistic combination of:
