The History segment of the Workouts tab is every workout you've finished, newest first.
Each card shows the routine you followed, the date, and a one-line summary of what you lifted. A 🌙 Deload badge means that day was logged as a deliberately lighter session; a green PR badge means you set at least one personal record that day.
History is a record of what actually happened — starting or editing a routine never changes anything you've already logged here. If a set's reps or weight got logged wrong, open the session and fix it there; history stays the place to look back, not the place targets get decided.
