The document discusses how a software engineer exercised while working from home during COVID-19. They bought a Nintendo Ring Fit Adventure game and wanted to track their exercise progress automatically. They outlined steps to get exercise data from tweets using APIs, recognize the data using OCR, and record the results on GitHub. Over 101 days of automation, they lost 2kg and gained physical and mental strength. Resources are provided for the GitHub Actions automation code and exercise log repository.
