Fitness (CTL) for long-term direction
Use CTL to check whether your block is progressing, not to force continuous increases.
How to use Fitness/Fatigue/Form
Read trend direction, short-term pressure, and freshness together before adjusting workload.
Fatigue (ATL) for short-term pressure
Use ATL to judge near-term stress and decide whether workload needs temporary relief.
Form (TSB) for session timing
Use TSB to decide whether to keep, move, or reduce key sessions before quality breaks down.
Change one variable, then recheck
Frequency, intensity, or duration: adjust one first, then validate against the next key workout.
Is Fitness/Fatigue/Form the same as PMC?
Yes, in most endurance contexts this naming maps directly to CTL/ATL/TSB-based PMC logic.
Does low form always mean no hard workouts?
Not always. Context matters. Evaluate recovery state, session priority, and recent execution quality.
How should beginners use this chart?
Keep it simple: avoid sudden spikes, preserve consistency, and make conservative adjustments.
