A bicycle ergometer includes an eddy current brake having a rotor assembly including an iron material having a carbon content of 0.12% or less and a silicon content of 0.35% or less, a stator provided in the rotor assembly, a plurality of exciting coils provided on the stator, and a power source for energizing the exciting coils. The ergometer includes an input panel for inputting physical attributes of the user, e.g., age and sex, a pulse sensor for measuring the heart rate of the user at rest and during exercise on the ergometer, an arithmetic control circuit for calculating a training program and heart rate range and for controlling the eddy current brake to present a load to the user which will maintain the user\s heart rate in a predetermined range. The method of using the ergometer enables a user to select a physical strength program and a weight reduction program with the selected program reflecting the age, sex, and the present physical condition of the user.

An ergometer for obtaining an optimum athletic load value for a user of an exercise device in which the legs of the user are bent and stretched to rotate a rotary unit having a variable load applied thereto during continuous exercise by the user, the athletic load value being increased step-wise in accordance with a linear load versus pulse rate correlation graph, the ergometer comprising: means for sequentially setting the load to first, second, and third levels; means for determining a first data corresponding to the pulse rate of the user at rest, a second data corresponding to the pulse rate of the user after exercise with the rotary unit having said first load level applied thereto, a third data corresponding to the pulse rate of the user after exercise with the rotary unit having said second load level applied thereto, and a fourth data corresponding to the pulse rate of the user after exercise with a rotary unit having said third load level applied thereto; means for providing a reference graph comprising the pulse rate versus load level correlation graph as computed by a minimum square law average; means responsive to said first, second, and third data for determining from said referenace graph said first, second, and third levels according to said first, second, and third data, respectively, and for controlling said setting means to sequentially set said load to said first, second and third levels; and optimum load determining means for determining an optimum load level for the user from said second to fourth data if said fourth data is less than an athletic safety pulse rate or from said first to third data if the pulse rate of the user reaches the athletic safety pulse rate before said determining means determines said fourth data.
