Abstract: Systems and methods presented herein generally provide for portable personalized training programs. More specifically, a mobile device (e.g., MP3 players, iPods, video game players, PDAs, cell phones, etc.) may provide to a user of the device a personalized physical fitness training program that enables the user to maintain physical fitness. In this regard, a physical fitness training program may be configured as one or more software modules wherein associated audio and video segments allow a user to view various physical fitness related training routines on the mobile device. The physical fitness training program may operably control these audio and video segments in a manner that allows the user to personalize a physical fitness routine. Such systems and methods may also have advantages and other types of personalized instruction.
