| 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.
