Abstract
An exercise apparatus that simulates uphill cycling where the user is able to maintain a preferred standing posture while programmed pedal platforms supporting each foot move through an exercise cycle that includes translating and non-parallel angular motion generated by a linkage mechanism. Simple harmonic load resistance acting upon the linkage mechanism is provided by drag pulleys or viscous damping cylinders for high intensity cycling exercise without dead center rotary crank problems.

An exercise apparatus that simulates uphill cycling where the user maintains a preferred standing posture comprising:
- an elongated base means adapted to rest upon a substantially flat surface, a pedal platform support means connected to said base means, an elongated pedal platform means to support the foot of the user, a linkage means connected to said pedal platform means and said pedal platform support means to cause said pedal platform means to move from a position substantially horizontal to said base means in a translating and non-parallel angular motion 360 degrees back to the starting substantially horizontal position to maintain the heel of the foot of the user substantially parallel to the said pedal platform means wherein the pedal platform means move in a pedal cycle as substantially shown in FIG. 2.
