Abstract: A system for monitoring the physical activity of a user comprises a portable medium and a remote server having access to a database containing data received from the portable medium. The portable medium has a sensor for detecting the movement of the user, a display, a memory, an interface for exchanging data with a gym machine, a processor for deriving in real time a dimensionless parameter representing the physical activity of the user wearing the portable medium, and wireless communication means configured to establish a connection between the portable medium and a mobile telephone which is set up to connect to the remote server to transfer data to the remote server in real time. The remote server is programmed to transmit, in real time, motivational indications as a function of the data transmitted by the portable medium for display on the mobile telephone.

Abstract: A system (1) for monitoring the physical of a user (2), comprises a portable medium (3) which can be worn by the user (2) and which is equipped with: a sensor (4) designed to detect a signal relating to the movement of the user (2); a display unit (6); a data storage memory (7); an interface (8) configured to allow data to be exchanged between the memory (7) and the gym machine (9); a processor (11) programmed for deriving in real time from the signal detected by the sensor (4), a dimensionless parameter value representing the physical activity of the user (2) wearing the portable medium (3) and for displaying an indication as a function of the derived value and a reference value; a remote server (12) having access to a database (13) containing data received from the portable medium (3), the portable medium (3) comprising wireless communication means (10) configured to establish a connection between the portable medium (3) and a mobile telephone (14) which is set up to connect to the remote server (12) to tra
