Wheelchair equipped with members (3, 5, 7, 9, 11) for training trunk and upper limbs muscles, characterised in that it is equipped with: - a first member for training shoulder muscles, namely deltoid, sternum-cleid-mastoid, brachial triceps muscles and back muscles, said first member being placed next to the backrest of the wheelchair, said first member comprising at least one first telescopic tube connected to an exercising handle, said first telescopic tube being adapted to be contained in and to go out of a corresponding elongated member for supporting the backrest, and being hinged (in a joint 20) to the elongated supporting member in order to be able to be inclined outside the supporting member, said first telescopic tube being further operatively connected to elastic holding and training means (22, 23); - a second member for training the brachial triceps muscles and the forearm deltoid and rotary muscles, said second member being adapted to perform pushing movements and rotary movements and being placed next to the armrests of the wheelchair, said second member comprising at least one second telescopic tube connected to a respective armrest adapted to rotate by 90° with respect to the second telescopic tube, said second telescopic tube being adapted to be contained in and go out of a corresponding elongated member for supporting the armrest, and being hinged (in joint 32) to the armrest to allow said 90°-rotation, said second telescopic tube being further operatively connected to elastic holding and training means; - a third member to perform traction exercises with the arm, namely with biceps and back muscles, exploiting the legs weight as resistance to movements, said third member being composed of at least one metallic lever equipped with a grasping handle which can be inserted into a corresponding seat connected to the structure used for resting the legs; and - a fourth member for training trunk and upper limbs muscles, said fourth member comprising the rigid backrest connected to two supporting members (50, 51) equipped with pins around which respective guides (53, 54) slide, each of said guides (53, 54) being composed of a half-guide fastened to the seating plane and a half-guide integral with the backrest and equipped with slit in which the pins are inserted, for the rotation, around the pin, of the supporting members towards outside with respect to the structure of the wheelchair, said fourth member being further equipped with elastic means for keeping its external rotation and the recall to its vertical rest position. - a first member for training shoulder muscles, namely deltoid, sternum-cleid-mastoid, brachial triceps muscles and back muscles, said first member being placed next to the backrest of the wheelchair, said first member comprising at least one first telescopic tube connected to an exercising handle, said first telescopic tube being adapted to be contained in and to go out of a corresponding elongated member for supporting the backrest, and being hinged (in a joint 20) to the elongated supporting member in order to be able to be inclined outside the supporting member, said first telescopic tube being further operatively connected to elastic holding and training means (22, 23);
