The present invention relates to a core exercise apparatus that combines lower arm movements with knee movements to exercise the core muscles of an operator in a cyclic manner. More particularly, the present invention is associated with an exercise apparatus having a separately supported knee platform for a portion of an operator coordinated with the motion of a lower arm platform. Further, the knees of the operator follow an elliptical curve path in concert with the up and down movements of the lower arm platform to drive a flywheel for cardio core exercise of the abdominal, lower and upper back muscles. The obliques may also be exercised by a reposition of the lower legs on the knee platform.

What is claimed is: 1. An exercise apparatus configured for core muscle exercise of an operator; a framework, said framework configured to support said exercise apparatus; a pair of crank arms, said crank arms being connected to rotate about a pivot axis positioned upon said framework; a lower arm platform for directly supporting both arms of an operator, said lower arm platform pivotally connected to said framework and one of said crank arms configured to follow generally up and down movement; a knee platform for directly supporting both knees of an operator, said knee platform connected to said framework and the other said crank arm configured for generally back and forth movement; wherein a downward force applied upon said lower arm platform in combination with a force applied upon said knee platform by said operator causes said crank arms to rotate about said pivot axis whereby the knees of said operator follow an elliptical curve path. 2. The exercise apparatus according to claim 1 further comprising a roller, said roller operably associated with said knee platform. 3. The exercise apparatus according to claim 1 further comprising an adjustable resistance device, said adjustable resistance device operably associated with said crank arms and said framework. 4. The exercise apparatus according to claim 1 wherein said crank arms have adjustable length to vary the motions of either platform. 5. The exercise apparatus according to claim 1 wherein a portion of said framework may be inclined whereby the orientation of said operator may be varied to cause the amount of effort for exercise to change. 6. The exercise apparatus according to claim 1 further comprising a guide, said guide operably associated with said knee platform and said framework. 7. The exercise apparatus according to claim 6 further comprising a coupler link, said coupler link pivotally connected to one of said crank arms and operably associated with said guide. 8. The exercise apparatus according to claim 1 further comprising a connector link, said connector link pivotally connected to one of said crank arms and operably associated with said lower arm platform. 9. The exercise apparatus according to claim 1 further comprising a pair of hand grips, said hand grips attached to said lower arm platform. 10. The exercise apparatus according to claim 1 further comprising a flywheel, said flywheel operably associated with said crank arms and said framework. 11. An exercise apparatus configured for core muscle exercise of an operator; a framework, said framework configured to support said exercise apparatus; a pair of crank arms, said crank arms being connected to rotate about a pivot axis positioned upon said framework; a lower arm platform for directly supporting both arms of an operator, said lower arm platform pivotally connected to said framework configured to follow generally up and down movement; a connector link, said connector link pivotally connected to one of said crank arms and to said lower arm platform; a knee platform for directly supporting both knees of an operator, said knee platform connected to said framework configured for generally back and forth movement; a coupler link, said coupler link pivotally connected to the other said crank arm and operably associated with said knee platform; wherein a downward force applied upon said lower arm platform in combination with a force applied upon said knee platform by said operator causes said crank arms to rotate about said pivot axis whereby the knees of said operator move towards the elbows of said operator to exercise the core muscles. 12. The exercise apparatus according to claim 11 further comprising a control system, said control system positioned on said framework and operably associated with the exercise intensity of said exercise apparatus. 13. The exercise apparatus according to claim 11 further comprising an adjustable resistance device, said resistance device operably associated with said crank arms and said framework. 14. The exercise apparatus according to claim 11 further comprising a guide, said guide operably associated with said knee platform and said framework. 15. The exercise apparatus according to claim 11 further comprising a flywheel, said flywheel operably associated with said crank arms and said framework. 16. An exercise apparatus configured for core muscle exercise of an operator; a framework, said framework configured to support said exercise apparatus; a pair of crank arms, said crank arms being connected to rotate about a pivot axis positioned upon said framework; an arm platform for directly supporting both arms of an operator, said arm platform having a pair of hand grips and being pivotally connected to said framework configured to follow generally up and down movement; a connector link, said connector link pivotally connected to one of said crank arms and to said arm platform; a knee platform for directly supporting both knees of an operator, said knee platform connected to said framework configured for generally back and forth movement; a coupler link, said coupler link pivotally connected to the other said crank arm and operably associated with said knee platform; a guide, said guide operably associated with said knee platform and said framework; wherein a downward force applied upon said arm platform in combination with a force applied upon said knee platform by said operator causes said crank arms to rotate about said pivot axis whereby the knees of said operator move towards the elbows of said operator to exercise the core muscles. 17. The exercise apparatus according to claim 16 further comprising an adjustable resistance device, said resistance device operably associated with said crank arms and said framework. 18. The exercise apparatus according to claim 16 further comprising a flywheel, said flywheel operably associated with said crank arms and said framework. 19. The exercise apparatus according to claim 16 further comprising a guide adjustment means, said guide adjustment means configured to change the orientation of the path followed by said knee platform. 20. The exercise apparatus according to claim 16 further comprising a pair of rollers, said pair of rollers attached to said knee platform and operably associated with said coupler link.
