01Preparedness
After a session, fatigue clears on the recovery window while fitness fades more slowly. Their difference is preparedness — how ready the muscle is to break its record.
Repairing → Primed → Fading. Fading never touches the level.
02Detraining
Real strength loss only starts past a per-muscle grace window (roughly 2–5 weeks, longer with training history, shorter with age). Past grace, 1RM decays toward a muscle-memory floor and is re-scored.
Training burns that deficit back off — one warm-up cannot erase a layoff. Decaying only labels the current long idle; leftover deficit can still suppress the number after you train again.
03States on Home
Repairing
Fatigue still clearing after the last session. The recovery bar is filling; readiness to PR is still low.
Primed
Fitness peaked and holds while preparedness stays ≥ 92%. Best window to break the record.
Fading
Preparedness faded below primed. Motivation cue only — the level number does not move.
Decaying
Idle past that muscle’s grace window. Modelled strength is actively shedding. The only state that can lower the level.
Untrained
No logged history on that muscle yet. The lane waits for the first honest sets.
04Why Home orders lanes
Home sorts by how overdue each muscle is relative to its own recovery rhythm — not a fixed calendar. Decaying floats up naturally.
