What is claimed:

1. Exercise machine comprising a frame provided with at least an upright substantially vertical and prismatically shaped; said upright supporting at least an elongated body ableto serve as a guide to a pack of flat bodies able to be actuated longitudinally for the execution of training exercises; each of said flat bodies presenting a portion transversely mated to said elongated body, to render said flat bodies angularly fixedand free to slide with respect to said elongated body; at least a plate supported by said upright in a position facing said flat bodies to isolate them from the outside; wherein said upright is externally delimited by a prismatically shapedlongitudinal shell, able laterally to cover said mated portions; longitudinal coupling means being provided to connect said upright and elongated body rigidly together; said plate being laterally delimited by at least one substantially rectilinearlongitudinal border; said shell presenting at least a longitudinal seat slidingly engaged by a said longitudinal border.

2. Machine according to claim 1, wherein said shell and said elongated body are rigidly connected together through the interposition of a longitudinal rib, realized from the same piece as said shell; substantially rectangular sections beingobtained from the same piece as said shell; each said mated portion having its plan form delimited by an open profile to form a seat facing said elongated body, in such a way that each said flat body is angularly fixed and free to slide vertically onthe elongated body itself.

3. Machine according to claim 2, wherein said connecting means of said elongated body comprise removable connecting organs.

4. Machine according to claim 2, wherein said elongated body is a metal rod presenting at least one rectilinear section set in a position of mated contact with said rib.

5. Machine according to claim 2, wherein said coupling means comprise welded connections between said elongated body and said rib.

6. Machine according to claim 2, wherein said upright is of the monolithic type, presenting said shell, rib, and elongated body obtained from a single piece.

7. Machine according to claim 6, wherein said shell presents a substantially C shaped cross section, and is longitudinally delimited by said two substantially rectangular longitudinal sections; each of said longitudinal sections being, in turn,delimited by said longitudinal seat.

8. Machine according to claim 7, wherein said upright is a product obtained by extrusion of a metallic material.

9. Machine according to claim 7, wherein said upright is made of light alloy.

10. Machine according to claim 9, wherein said upright presents substantially E-shaped cross section, said rib together with said elongated body representing the central leg of the E.

11. Machine according to claim 2, wherein said upright is made of composite material.

12. Machine according claim 1, wherein said frame comprises a pair of uprights, and a connecting organ positioned between them and above said pack of flat bodies; in such a way as to refer them with respect to one another and to connect themrigidly.

13. Machine according to claim 12, wherein said connecting body comprises a lid of the boxed type to house internally, in a manner freely ro-Lating and axially fixed, at least one transmission pulley for a flexible organ; said flexible organbeing connected to said pack of flat bodies for the respective actuation along said elongated body.

14. Machine according to claim 12, wherein each said flat body presents a pair of mated portions, each whereof being slidingly coupled to a respective elongated body; each said flat body presenting respective friction reducing means able tofavor the free sliding of the flat body itself on said elongated bodies.

15. Machine according to claim 14, wherein said friction reducing means comprise inserts of plastic material presenting high sliding ability in contact with the respective metal rods in correspondence with the respective mated portions.

16. Machine according to claim 14, wherein the friction reducing means comprise a coating of said flat bodies, said coating being made of material presenting high sliding capability in contact with said metallic rods.
