An exercising device which yields a variable, programmed speed for regulating the user's movement is disclosed. The device includes a user interfacing device for input of the user's efforts, a variable speed regulator connected to and driven by the interfacing device, a user position sensor also connected to the interfacing device, and a speed programmer connected to both the position sensor and the variable speed regulator. By means of a varying references voltage which it delivers to the speed regulator, the programmer establishes a preselected pattern of varying speed to regulate the user's movement. The user position sensor may take a variety of forms. It may sense the absolute position of the user in the range of motion of the exercise, it may measure the distance of the user from the starting point, or it may calculate the user's position according to time elapsed from the beginning of movement in the exercise.
