ABSTRACT:
An improved exercise apparatus, having two rails in parallel relation supported on a frame. Supported internally to each rail are two travellers, the four travellers for engagement with the limbs of the user. Each pair of travellers is supported internally to the rail one above the other, with the bottom travellers extending outwardly beyond the sides of the apparatus. The travellers ride within grooves in the rails. Also supported within each rail is an endless chain means. When the travellers are coupled to the endless chain means, the user encounters a resistive force from a force resistance system. Each set of travellers is selectively coupled to the respective endless chain means.
