ABSTRACT:
The invention is a collapsible exercise machine that is transportable in a container and includes a load-regulating hydraulic cylinder. The machine according to the invention is characterized in that it comprises a frame having a column formed of elements that can be folded onto a base for carriage and two detachable legs arranged on opposite sides of the frame and on which are adjustably mounted two benches for accommodating a user, one of the foldable elements being formed of a housing containing a translation system and the load-regulating hydraulic cylinder. The hydraulic cylinder comprises a piston provided with a rod connected by a first bar to sliding rods themselves connected to a second bar on which is wound via a case a strap connected by transmission members to exercise members actuated by the user. The exercise machine according to the invention can be easily collapsed and transported, especially in a container the shape of which closely matches that of the exercise machine in its collapsed position and that best approximates the aerodynamic characteristics necessary for carriage on all automobile roof racks.
