Abstract: A computer-implemented method can include receiving a first input from a user, obtaining a video file in response to the first input, outputting the video file for display to the user. The first input can be received by a computing device having one or more processors. The first input can be representative of a physical exercise to be performed by the user, the exercise associated with a muscle. The computing device can obtain the video file of an animated human form, an écorché, performing the physical exercise in response to the first input. The computing device can output the video file for display to the user. The display of the at least one muscle of the animated human form in the video file is visually-enhanced relative to other portions of the animated human form in the video file.
