What is claimed is: 1. An exercise device comprising: at least one vacuum cylinder, wherein the at least one vacuum cylinder requires no external source of compressed gas, and wherein the at least one vacuum cylinder comprises a cylinder shaft; at least one flywheel operatively connected to the at
What is claimed is: 1. An exercise device comprising: at least one vacuum cylinder, wherein the at least one vacuum cylinder requires no external source of compressed gas, and wherein the at least one vacuum cylinder comprises a cylinder shaft; at least one flywheel operatively connected to the at least one vacuum cylinder; a flywheel gear train operatively connected to the cylinder shaft, wherein the flywheel gear train comprises: at least one rod; and one or more gears operatively connected to the at least one rod such that the at least one rod rotates when the cylinder shaft is extended or retracted, wherein the at least one flywheel is operatively connected to the at least one rod, such that when the at least one rod rotates, it causes the at least one flywheel to rotate; and an armbase slider mechanism means, connected to the cylinder shaft, for varying a resistive exercise load. 2. The device of claim 1, further comprising a frame operatively connected to the at least one vacuum cylinder. 3. The device of claim 2, further comprising a platform connected to the frame. 4. An exercise device comprising: at least one vacuum cylinder, wherein the at least one vacuum cylinder requires no external source of compressed gas, and wherein the at least one vacuum cylinder comprises a cylinder shaft; at least one flywheel operatively connected to the at least one vacuum cylinder; a flywheel gear train operatively connected to the cylinder shaft, wherein the flywheel gear train comprises: at least one rod; and one or more gears operatively connected to the at least one rod such that the at least one rod rotates when the cylinder shaft is extended or retracted, wherein the at least one flywheel is operatively connected to the at least one rod, such that when the at least one rod rotates, it causes the at least one flywheel to rotate; and an armbase assembly operatively connected to the cylinder shaft, wherein the armbase assembly is comprised of two sides and a slider mechanism slideably connected to the two sides wherein the slider mechanism varies the position of the cylinder shaft of each of the at least one vacuum cylinder relative to the armbase assembly. 5. The device of claim 4, wherein the armbase assembly is further comprised of a pivot axis operatively connected to the armbase assembly such that the armbase assembly pivots about the pivot axis and wherein the armbase assembly has a shaft connection end and a force application end, such that when a force is exerted on the force application end, the armbase assembly pivots about the pivot axis and the shaft connection end causes the cylinder shaft of each of the at least one vacuum cylinder to extend. 6. The device of claim 5, wherein each of the two sides is comprised of a curved track and wherein the armbase assembly is further comprised of: a ball screw operatively connected to the slider mechanism; a crank operatively connected to the ball screw; at least one shaft end interface operatively connected to the cylinder shaft of each of the at least one vacuum cylinder; and a cross bar operatively connected to the slider mechanism and the at least one shaft end interface. 7. The device of claim 4, further comprising a wishbone arm and a lift bar, wherein the wishbone arm is operatively connected to the armbase assembly and the lift bar is operatively connected to the wishbone arm. 8. The device of claim 4, further comprising two cable arms, operatively connected to the armbase assembly on each of its sides. 9. The device of claim 8, further comprising at least two cables, wherein at least one cable is operatively connected to each of the two cable arms. 10. The device of claim 9, further comprising at least one pulley operatively connected to at least one of the at least two cables, wherein the at least one pulley is comprised of a predetermined load ratio for a load application to each of the at least two cables. 11. An exercise device, comprising: at least one vacuum cylinder comprised of a cylinder shaft; a gear rack operatively connected to the cylinder shaft; a rotatable first rod operatively connected to the gear rack, the rotatable first rod having a first helical gear operatively connected to the first rod and a spur gear operatively connected to the first rod wherein the spur gear also operatively connects to the gear rack such that when the cylinder shaft is extended or retracted, the first rod and the first helical gear rotate; a rotatable second rod operatively connected to the rotatable first rod, the rotatable second rod having at least one flywheel operatively connected to the second rod and a second helical gear operatively connected to the second rod, wherein the second helical gear operatively contacts the first helical gear such that when the first helical gear rotates, the second rod and the at least one flywheel rotate; and an armbase slider mechanism means operatively connected to the cylinder shaft for varying a resistive exercise load. 12. The device of claim 11, further comprising a frame operatively connected to the at least one vacuum cylinder. 13. The device of claim 12, further comprising a platform connected to the frame.
