ATL (Acute Training Load)

Definition

ATL (Acute Training Load) represents your current fatigue — a 7-day exponentially weighted moving average of your daily TSS. Often called "fatigue."

Why it matters

ATL tracks how much training stress you have accumulated recently. High ATL = significant fatigue. Combined with CTL, ATL is used to calculate TSB (form/freshness).

How FlipMP uses it

FlipMP displays your ATL alongside CTL and TSB. When ATL spikes dramatically, the AI coach flags overtraining risk and may recommend reducing load.
