A combined anaerobic and aerobic exercise system comprises a multi-part frame, for example a telescoping frame, or a pivoting frame. The aerobic system may include an elliptical exercise device, while the anaerobic system may include a cable-based system wherein resistance is adjustable. An electronic console system at the exercise system allows a user to view progress in both anaerobic and aerobic workouts, and to send input signals that adjust anaerobic and aerobic resistance mechanisms.
