Claim:
1. A fitness system for enhancing the effectiveness and efficiency of physical training and/or exercise by a user comprising: a plurality of sensors that are worn by an exercising user and which generate data concerning monitored body processes pertaining to effects of an exercise on the user's body, the plurality of sensors including at least one muscle sensor having a plurality of electrodes for placement at a like plurality of positions on a monitored muscle or muscle group, and an additional electrode for placement at a signal reference point on the user's body, the plurality of sensors further including a pulse sensor for producing a pulse-rate signal indicative of the user's pulse rate, and a breath-rate sensor for producing a breath-rate signal indicative of the user's breath rate; a processor for receiving the data from the plurality of sensors, processing said data, storing said data, and sending the processed data to a host device, said processor including one or more differential amplifiers for receiving the data generated by respective muscle sensors and generating respective muscle sensor signals and an RMS value of the muscle sensor signals, one or more RMS-to-DC converters for converting the RMS value of the muscle sensor signals to DC values, and a multiplexor for sampling successive DC values from the one or more RMS-to-DC converters and of the pulse-rate signal and breath-rate signal to produce a series of digital bits representing the sampled values in a multiplexed manner; a host device in digital communication with the processor via a wireless communication protocol for receiving the sampled values, and a display device for displaying the sampled values in real time in a visually comprehensible format to at least one of the user or a fitness trainer.
