Field notes
The player is described as taking a link, pasted workout, or `.pwf.json` file, then running timers, counting rounds, and showing the next step on a phone, laptop, or TV. The examples encode practical session details—including 30/30 intervals and station rotations—rather than just naming exercise categories; the site says its timing rules are tested, a claim not independently verified here.
