EXERCISE APPARATUS In the subject apparatus the user lies, back down, on a shuttle platform which it mounted on parallel tracks and movable from end to end of the tracks. The shuttle is biased toward a position between the ends by primary and secondary energy storage and release apparatuses. The engagement of the shuttle and track assembly by the primary energy storage and release apparatus is constant. The secondary energy storage and release apparatus is constantly engaged with the shuttle and intermittently engaged with the track assembly. Both apparatuses are adjustable in terms of the at rest position of the shuttle on the track assembly and the forces in the apparatuses when at rest and in operation. Hand grips are attached to the track assembly by cables and are used by the user for setting the platform into oscillating motion on the track. The acceleration forces achieved may be in excess of the force of gravity and the shuttle is equipped with supports and restraints for stabilizing the position of the user on the shuttle. The exercise provides cardiovascular stimulation, passive exercise of all components of the body and the active exercise of setting the shuttle in motion and maintaining the motion. |
