Claim One:
1. An apparatus for monitoring, analyzing, and providing feedback on physical activity of a user, comprising: a controller; a garment configured to be worn on a portion of a body of the user, the garment including: a fabric including a set of electrode bases, each electrode base in the set of electrode bases made from a conductive resin material formed on the fabric, wherein the fabric is composed of a stretchable, compressive and form-fitting material configured to bias each of a set of electromyography sensors into contact with a plurality of muscles on the user when the user dons the garment, wherein the fabric comprises at least one of nylon, polyester, spandex, and synthetic fibers, the set of electromyography sensors coupled to the set of electrode bases and configured to acquire bio-potential signals indicative of muscle activation, and a set of conductive leads coupled with each electrode base in the set of electrode bases and configured to couple to the controller, each conductive lead in the set of conductive leads composed of a flexible and electrically conductive material that is positioned on the fabric; and a processing system including a first module configured to receive information characterizing a user profile of the user, a second module configured to receive signals derived from the set of electromyography sensors from the controller, and a third module configured to calibrate the set of electromyography sensors based upon the user profile, wherein the third module comprises a calibration circuit configured to receive an input signal derived from a pair of electrodes at a variable gain block of the calibration circuit, wherein the variable gain block is configured to scale the input signal by a gain factor having an initial preset value based on a body mass index parameter of the user determined from the user profile of the user.
