1. An exercise device comprising:

  • a frame intended to rest on a floor or other supporting surface, said frame having a crank axis which is essentially perpendicular to the longitudinal axis of said exercise device;

    a pair of cranks, each crank rotatably connected to said frame at said crank axis;

    a pair of output links each having a pair of distal ends and a medial portion, said output links operably connected to a respective crank, wherein each output link is rotatably connected to its respective crank at its medial portion thereby defining a first connection point, each said output link operatively connected to said frame near one of said distal ends thereby defining a first pivot point, that limits movement in a first reciprocating path relative to said frame;

    a pair of intermediate links each having a pair of distal ends and a medial portion, wherein each intermediate link is operatively connected to said frame near one of said distal ends thereby defining a second pivot point that limits movement in a second reciprocating path relative to said frame, and where each said intermediate link is rotatably connected at its medial portion to the second distal end of a respective output link thereby defining a third pivot point; and

    ,a pair of elongated pedal arms, each pedal arm having a surface area for an individual to stand upon with one foot and an axle, each pedal arm operatively connected to a respective intermediate link near the end distal from said second pivot point thereby defining a pedal arm pivot point, said axle operatively engaging said frame thereby limiting movement in a third reciprocating path relative to said frame; and

    , wherein each of said pedal arm pivot points travel in a substantially tear-drop cyclic path in response to displacement of said pedals arms along said third reciprocating path.
