Apparatus for the assisted performance of a fitness exercise

A method to assist a user in the performance of a fitness exercise using an exercise machine comprising a frame, a weight stack movably associated with the frame to define the resistant load, and at least one mobile element connected to the resistant load by a cable and movable by the user along a preset path overcoming the resistant load,

• wherein the method comprises the following steps:
• sensing through a detector a signal representing the movement of the user, when the user performs the fitness exercise through the exercise machine;
• comparing in real time the signal representing the movement of the user with a preset reference pattern, representing an ideal pattern for the movement of the user corresponding to the fitness exercise performed correctly, wherein said comparison is carried out by a processor connected to the detector and to a feedback generator;
• transmitting to the user in real time a signal on the correctness of the performance of the exercise, according to the result of the comparison, wherein said signal is transmitted through the feedback generator,
• wherein said signal transmitted in real time to the user comprises:
• (i) a graphical representation of the body of the user generated by a succession of user positions and (ii) graphical elements based on the reference pattern and representative of the difference between the signal representing the movement of the user and the predetermined reference pattern,
• wherein said graphical elements are transmitted to the user only when the difference between the signal representing the movement of the user and the predetermined reference pattern exceeds a predetermined tolerance margin, whereby no reference pattern is displayed as long as the difference between the signal representing the movement of the user and the predetermined reference pattern is less than or equal to said predetermined tolerance margin.
