ABSTRACT:
Dual facing diammetrically-opposed either independently activatable or electrically or mechanically linked exercise stations are provided on a common base so diammetrically-opposed users can have an unobstructed view of each other and so that common components can serve each station. The dual facing machines having common structural components, common energy absorption components, common housing components, common hand rail components and common instrument components provide for diammetrically-opposed users in a close relationship so that both social as well as face-to-face competitive exercise is acheivable through interactive control of the exercise stations. Dual facing machines include dual stairclimbing devices, dual exercise bicycles, dual rowing machines or dual tread mill devices.
