Abstract: Certain embodiments of the present invention are directed to automated human-motion-training systems. These automated human-motion-training systems include a hardware platform that provides for stored-instruction processing and that includes memory, an I/O interface, and an audio-signal generation and output component, and an operating system or control program that executes on the hardware platform and that provides a program-execution environment. The automated human-motion-training systems further include components of the human-motion-training system that provide for automated proctoring of human-motion exercises and training regimes, including monitoring of a user's body position, producing feedback corresponding to a user's body position, and determining a user's performance in order to modify the exercises and training regimes so that they provide optimal-challenge-point-based training over the course of multiple repetitions and training sessions.
