A method for storing an exercise performance of a user of an exercise device (UE1, UE2, UE3) that is shared by several users (U1, U2, U3), the method comprising - installing into the exercise device (UE1, UE2, UE3) software for identifying the user (U1, U2, U3), said method comprising the steps of: a) assigning a first identifier to the user (U1, U2, U3) of the exercise device (UE1, UE2, UE3); b) assigning a second identifier to the exercise device (UE1, UE2, UE3); c) identifying dynamically and automatically the user (U1, U2, U3) of the exercise device (UE1, UE2, UE3) in response to the first identifier; d) associating the first identifier with the second identifier, wherein said method further comprises the steps of: e) collecting information on the exercise performance of the user (U1, U2, U3) in an automated manner from the exercise device by associating the combination of the first and second identifiers with the information related to the exercise performance; e1) transmitting (2-6, 2-8) said information on the exercise performance of the user (U1, U2, U3) from the exercise device to a centralized database installed on and/or connected to a remote server by using a fixed and/or wireless TCP/IP connection; f) storing in said centralized database information related to the exercise performance user-specifically and device-specifically; f1) granting the user (U1, U2, U3) rights to the information in the database in response to the identification of the user; g) searching for information from the centralized database and returning said information to the user (U1, U2, U3) during the exercise or after it by providing the user (U1, U2, U3) with a remote read rights to the information related to the exercise performance over a data network, in particular a mobile network and/or an Internet protocol network, wherein in said step c) the user is identified by a Bluetooth signal transmitted by a user equipment and wherein said user equipment is a user's mobile phone. - installing into the exercise device (UE1, UE2, UE3) software for identifying the user (U1, U2, U3), a) assigning a first identifier to the user (U1, U2, U3) of the exercise device (UE1, UE2, UE3); b) assigning a second identifier to the exercise device (UE1, UE2, UE3); c) identifying dynamically and automatically the user (U1, U2, U3) of the exercise device (UE1, UE2, UE3) in response to the first identifier; d) associating the first identifier with the second identifier, wherein said method further comprises the steps of: e) collecting information on the exercise performance of the user (U1, U2, U3) in an automated manner from the exercise device by associating the combination of the first and second identifiers with the information related to the exercise performance; e1) transmitting (2-6, 2-8) said information on the exercise performance of the user (U1, U2, U3) from the exercise device to a centralized database installed on and/or connected to a remote server by using a fixed and/or wireless TCP/IP connection; f) storing in said centralized database information related to the exercise performance user-specifically and device-specifically; f1) granting the user (U1, U2, U3) rights to the information in the database in response to the identification of the user; g) searching for information from the centralized database and returning said information to the user (U1, U2, U3) during the exercise or after it by providing the user (U1, U2, U3) with a remote read rights to the information related to the exercise performance over a data network, in particular a mobile network and/or an Internet protocol network, e) collecting information on the exercise performance of the user (U1, U2, U3) in an automated manner from the exercise device by associating the combination of the first and second identifiers with the information related to the exercise performance; e1) transmitting (2-6, 2-8) said information on the exercise performance of the user (U1, U2, U3) from the exercise device to a centralized database installed on and/or connected to a remote server by using a fixed and/or wireless TCP/IP connection; f) storing in said centralized database information related to the exercise performance user-specifically and device-specifically; f1) granting the user (U1, U2, U3) rights to the information in the database in response to the identification of the user; g) searching for information from the centralized database and returning said information to the user (U1, U2, U3) during the exercise or after it by providing the user (U1, U2, U3) with a remote read rights to the information related to the exercise performance over a data network, in particular a mobile network and/or an Internet protocol network,
