A system and non-intrusive method for exercise posture detection are provided. The system includes a mat, at least one sensor matrix comprising one or more sensors and configured to generate an electrical signal upon making a contact by the user with the mat, a plurality of sensor lines, a plurality of power lines and a processing subsystem. The processing subsystem includes a data acquisition module configured to extract a first set of data, to extract a second set of data; a data processing module to process the first set of data and the second set of data, to concatenate the first set of data and the second set of data to get a final set of data, to compare the final set of data with a pre-defined set of posture data, to determine the posture of the at least one exercise.
