How edits apply
Changes are stored as a draft until applied. Only sessions from the effective week/day onward use the updated configuration. Past prescriptions and logged sets are retained.
Resume an earlier workout
Targets are prefilled. Tap Done after each performed set.
Session notes and optional RPE / duration
Brief wellness check
Self-reported hours, not sleep-stage tracking.
0 = none · 10 = extreme fatigue
0 = none · 10 = extremely high
0 = none · 10 = extremely severe
This is separate from the four monitoring measures and is not included in any score. Concerning symptoms warrant appropriate assessment, not a load adjustment suggested by the app.
No pre-workout check is required to log a session. Saving a correction preserves the earlier entry in your backup's wellness audit trail.
Mesocycle review
Review notes / next mesocycle
Document observations and decisions. Notes don't modify training prescriptions.

Data & installation
Checking saved data…
Installation: after free HTTPS hosting, open the URL in Chrome/Edge and choose Install, or on iPhone open it in Safari and use Share → Add to Home Screen. Installation does not synchronize data between devices. Offline availability requires visiting the hosted app once while connected and leaving its site data intact.
Backups are plain JSON files. Keep a copy in a private, safe location. Export before updating, changing browsers, clearing data or restoring a different backup.
Method
TM = training max. RIR = estimated repetitions in reserve. Main-lift progression follows the Stronger By Science Last Set RIR workbook; the source spreadsheet is not modified.
