In the preferred and illustrated embodiments, an interactive exercise device is disclosed. One embodiment utilizes an exercise bicycle wherein wheel speed and force are monitored. An electromagnetic brake is adjusted by a control apparatus to relate the measured force to the required force. The electromagnetic brake controls the drag to implement a selected exercise program. The program paces the user through a specified load for a specified interval. The work load can be varied in any manner to achieve a desired exercise program. The interactive apparatus utilizes a video monitor to display an exercise program or race for the user. The race or exercise program is recorded on a video cassette. On playback, the cassette provides video for the monitor to be viewed by the user. The audio track is conveniently used to record instructions which are converted into a drive current for the brake, thereby modifying the drag and required velocity of the user. An alternative form is presenting exercise instructions on the video monitor via graphics or stored symbols. An alternative embodiment utilizes dead weight lifting equipment either with a linearly moved bar or a rotated shaft to provide an exercise program paced to the user.
