A system for electrically stimulating one or more muscle groups includes a processor-readable storage medium storing, in association with each of at least one muscle group, digital exertion data representative of one or more action potentials captured during an exertion regime from the muscle group of a respective subject; a signal generator for generating electrical stimulation signals; processing structure configured to automatically retrieve digital exertion data from the processor-readable storage medium and to automatically cause the signal generator to generate new electrical stimulation signals based on the digital exertion data; and a signal distributor for conveying the new electrical stimulation signals from the signal generator to one or more respective muscle groups of at least one different subject. Also provided is a system for providing exercise session data including a capture subsystem capturing one or more action potentials from at least one muscle group of a subject during an exertion regime, the capture subsystem including a processor-readable storage medium; processing structure generating digital exertion data representative of the one or more action potentials and creating the exercise session data by: storing the digital exertion data in association with an identification of the respective muscle group in the processor-readable storage medium; storing, in the processor-readable storage medium, one or more exercises each defining at least the digital exertion data for one or more muscle groups; and storing, in the processor-readable storage medium, one or more sessions each defining at least one or more of the exercises, a publishing subsystem for publishing the exercise session data for download and use by at least one different subject to cause another processing structure to generate and distribute new electrical stimulation signals to one or more respective muscle groups of the at least one different subject. Related methods are disclosed.
