Abstract
A common frame and display is employed for use as a treadmill and elliptical exercise apparatus. Interlock switches are used to lock out one system electrically while the other is in use. The elliptical system employs folding pedal arms which engage switches in a folded stowed state to disable or enable each system according to the folded state of the pedal arms. When the arms are folded, the treadmill mode is enabled and the elliptical mode is disabled and when unfolded, the elliptical system is enabled and the treadmill system is disabled. The display displays speed, elevation, and distance traveled in each mode and includes a resistance in each mode to vary the work load on the user.
