1. A computer-implemented method of controlling a force generator of an exercise apparatus, the method comprising:
determining or receiving angular positions of a rotatable axle of the exercise apparatus when a force is applied to a force receiving structure of the exercise apparatus, the rotatable axle connecting the force receiving structure to the force generator which is controlled by a computer based on a kinetic model, the kinetic model being based on equations of motion of an exercise on the exercise apparatus;
determining or retrieving first geometrical scaling values associated with the angular positions and using the first geometrical scaling values in the kinetic model to form a first modified kinetic model, the first geometrical scaling values being used for simulating a first non-circular gear of a first predetermined non-circular geometry; and
determining applied force values for the angular positions, each of the applied force values representing the force that is applied to the force receiving structure; and,
controlling the force generator based on first resistive force values so that the exercise apparatus behaves an exercise apparatus comprising a mechanical power transmission system including the first non-circular gear, the first resistive force values being computed using the first modified kinetic model and the applied force values.
