Abstract
An apparatus permitting a user to perform a simulated stair climbing exercise includes left and right foot platforms pivotally connected to a frame by respective unequal-length four-bar linkages. The linkages maintain the foot platforms generally perpendicular to the user's lower leg during the exercise as the foot platforms are alternately depressed by the user. An eddy current brake provides the desired resistance to the user's simulated stair climbing. A display with a touch-sensitive screen is mounted on the frame and allows the user to input information to a processor which controls the resistance of the eddy current brake and other functions. The display also includes an integral television tuner that allows the user to view either a simulated image of the user performing the stair climbing exercise or a standard television program on the display during the exercise.
