Bio signal
Bio. What her body is telling the watch.
Heart-rate variability, resting heart rate, sleep duration, recovery trends. The wearable data she already has, turned into something she can actually use.
What it measures
Heart-rate variability (HRV)
The gold-standard recovery metric. Higher HRV means her nervous system is ready to train; a sudden drop means it isn't — regardless of how she feels.
Resting heart rate
The simplest trend that matters. When resting heart rate creeps up over three days, her body is fighting something — even if she doesn't know it yet.
Sleep duration & quality
Hours in bed, time asleep, restfulness. The objective side of the sleep story, measured by the device on her wrist.
Recovery signal
Heart rate, sleep quality and recovery, read together and reported as their own signal — not folded into a single number.
What you see
Recovery trends over time. When her HRV drops and her resting heart rate rises, the system knows she needs lighter training — before she feels it.
What she does
Nothing extra. If she wears an Apple Watch, Garmin, or Whoop, the data flows in automatically.
Why it matters
Subjective feel is one signal. Objective biology is another. When they agree, confidence is high. When they disagree — she says she feels fine but her HRV says otherwise — that's when the system earns its keep.
