1. A portable elliptical exercise apparatus, comprising: a) a base plate;b) a chassis connected to the base plate;c) an anchor element extending upwards from the chassis;d) a front bar connected to an end of the chassis for stabilizing the portable elliptical exercise apparatus during use;e) a left pedal;f) a left cross-shaped stabilizer having a first end and a second end, wherein a first end of the left pedal is connected to the first end of the left cross-shaped stabilizer, andwherein a second end of the left pedal is connected to a left wheel,g) a right pedal;h) a right cross-shaped stabilizer having a first end and a second end, wherein the second end of the right cross-shaped stabilizer is opposite the first end of the left cross-shaped stabilizer,wherein a first end of the right pedal is connected to the first end of the right cross-shaped stabilizer, andwherein a second end of the right pedal is connected to a right wheel,i) a pulley; wherein the pulley, the left cross-shaped stabilizer, and the right cross-shaped stabilizer are coupled to the anchor element along a common rotation axis,wherein concurrent rotation of the left cross-shaped stabilizer and rotation of the right-cross-shaped member causesrotation of the pulley,movement of the left and right pedals in an elliptical shape, andmovement of the first wheel and second wheel in opposing directions along the base plate;j) a looped belt configured to couple the pulley to a resistance assembly, wherein the resistance assembly is coupled to the base plate; andk) a tension stabilizer configured to maintain a tension of the looped belt on the pulley. 2. The portable elliptical exercise apparatus according to claim 1, wherein the resistance assembly is configured to assert a resistance to the left pedal and the right pedal through the looped belt, wherein the resistance is adjusted by changing a distance between a flywheel element and a corresponding magnetic plate element of the resistance assembly, the magnetic plate asserting a magnetic force over the distance on the flywheel element and the looped belt looping around a co-rotating extension from the flywheel element. 3. The portable elliptical exercise apparatus according to claim 2, wherein the common rotation axis is at a predetermined height such that the left pedal and right pedal range between approximately 2 degrees and 32 degrees from horizontal through the concurrent rotation of the left cross-shaped stabilizer and of the right-cross-shaped member. 4. The portable elliptical exercise apparatus according to claim 1, wherein a mass ratio between the left cross-shaped stabilizer and the pulley is approximately 2 to 1. 5. The portable elliptical exercise apparatus of claim 1, wherein a rotational diameter ratio between the pulley and the left cross-shaped stabilizer is approximately 4 to 3. 6. The portable elliptical exercise apparatus of claim 1, further comprising: a cover covering the pulley and the resistance assembly,wherein the cover comprises a handle located between the pulley and the resistance assembly.
