1. A variable motion exercise apparatus, comprising: a) a frame designed to rest upon a floor surface;b) a left crank and a right crank, wherein each said crank is mounted on a respective side of said frame and rotatable about a common crank axis;c) a left rocker link and a right rocker link, wherei

1. A variable motion exercise apparatus, comprising: a) a frame designed to rest upon a floor surface;b) a left crank and a right crank, wherein each said crank is mounted on a respective side of said frame and rotatable about a common crank axis;c) a left rocker link and a right rocker link, wherein each said rocker link is mounted on a respective side of said frame and rotatable about a common pivot axis;d) a left foot support member and a right foot support member, wherein a forward distal end of each said foot support member is pivotally connected to a respective rocker link and a rearward portion of each said foot support member is in rolling contact with a roller rotatably mounted on each said crank;e) a left drawbar linkage and a right drawbar linkage, wherein said drawbar linkage is movably connected between a respective rocker link and a respective crank in such a manner that a foot supporting portion of each said foot support member is constrained to move through a generally elliptical path as a respective crank rotates;f) an actuator operatively connected to each said drawbar linkage;g) sensor means for generating an output signal responsive to user applied force to each said rocker link and/or each said foot support member; andh) a control console that receives the output signal and transmits a control signal to said actuator to adjust the position of each said drawbar linkage relative to a respective rocker link to alter a respective path. 2. The exercise apparatus of claim 1, wherein each said drawbar linkage includes a drawbar and a drawbar rocker pivotally connected to one another, and wherein an end of said drawbar is rotatably connected to a respective crank and an end of said drawbar rocker is operatively connected to said actuator. 3. The exercise apparatus of claim 2, including a lever arm pivotally connected to an upper distal end of said drawbar rocker and wherein said lever arm is operatively connected to said actuator. 4. The exercise apparatus of claim 3, wherein said sensor means includes one or more sensors that generate an output signal responsive to user applied force to each said rocker link and/or each said foot support member. 5. The exercise apparatus of claim 1, wherein said sensor means includes a crank position sensor and an idler pressure sensor. 6. The exercise apparatus of claim 5 including a trigger disk fixedly secured to said crank. 7. The exercise apparatus of claim 6 wherein said trigger disk includes indicia measured by said crank position sensor for detecting the angular position of said crank.
