Field notes
The training loop pairs user-defined boxing combinations with visible color cues and spoken callouts, allowing a trainee to follow rounds without another person calling commands. The page gives a concrete three-color example—green for jab, yellow for jab-cross, and red for jab-cross-left uppercut—and shows a 2:31 first-round display. It also describes a gym-TV mode using a webcam as a mirror substitute, with no recording or transmission in that workflow.
