An apparatus for developing muscles comprises a bar (4) operated by means of an electronically controlled hydraulic force jack (7) which can move said bar downward, from left to right, without any form of chain, transmission or guiding. The base of the force jack (7) is attached to the support (2) at the appropriate height and its head is attached to the appropriate part of the muscle developing bar (4). Said bar forms a telescopic lever arm (4) and is actuated by a geometry jack or correction jack (10). The transmission energy is hydraulic and electronic; the two constitute the programmable electrohydraulic control. The invention is applicable to muscle developing appliances.
