A vertical stepping machine includes a frame, a crank wheel connected to the frame, a crank wheel connected to the frame, a pedal beam having a first end and a second end, wherein the first end is in mechanical communication with the crank wheel, a pedal connected to the second end of the pedal beam, a linkage assembly connected to the frame and to the pedal beam, an arm support rotatably connected to the frame, an arm linkage connecting the arm support to the linkage assembly, and a rotary resistance mechanism positioned above the crank wheel when the vertical stepping machine is in an upright orientation. The pedal beam moves in an elliptical path when the crank wheel rotates and the elliptical path has a vertical major axis and a horizontal minor axis when the vertical stepping machine is in an upright position. |
