What readiness is
Readiness is a score for how recovered your body is and how prepared it is to take on load today. Not a vague "how do you feel" — a numeric signal built from objective overnight data.
The idea is simple: training is stress, and progress happens during recovery. Load a body that hasn't recovered yet and you don't grow — you stack up fatigue. Readiness shows which phase you're in today: push, or back off.
What readiness is built from
A single metric lies. Readiness combines several signals that together paint an honest picture:
- HRV (heart-rate variability). The main marker of your autonomic nervous system. HRV high relative to your norm means the body is in recovery mode. A sharp drop means it's under stress — from load, poor sleep, illness or alcohol.
- Resting heart rate (RHR). A morning pulse above your usual is almost always a sign of incomplete recovery or an oncoming cold.
- Sleep. Not just duration but structure — deep and REM stages. There's no recovery without sleep, and no supplement replaces it.
- Recent load. Yesterday's hard intervals will naturally lower today's readiness. That's not a fault — it's the expected cost of the work.
Why a personal baseline beats a textbook norm
This is what separates useful readiness from a pretty number on a screen.
Population norms are nearly useless. One person's resting HRV of 40 ms is perfectly normal and stable. Another's is 90 ms. Comparing them to each other is meaningless. Only one thing matters: how today's numbers compare with YOUR personal norm.
So a proper system first watches you for a few weeks and builds a personal baseline — your usual range for HRV, heart rate and sleep. From then on readiness doesn't answer "are you healthier than average?" but "are you above or below your own normal today?" That's the only comparison that matters for training.
Why measure it in the morning
Readiness is measured in the morning, right after waking, for a reason. Overnight the body is in its cleanest, least-disturbed state: no coffee, no meeting stress, no daily noise. Your morning HRV and resting heart rate are the most honest snapshot of what you actually woke up with.
Measure it midday and you get noise — the reaction to caffeine, emotions, lunch. That's why the morning reading became the standard: it's the base you build the whole day's decision on.
One bad night is not a verdict
Here's the nuance that trips people up. A single readiness dip decides nothing. You slept badly after a flight, stress or a glass of wine — HRV sank, and that's normal. The body is supposed to respond that way.
What's dangerous isn't one dip — it's a trend. If readiness falls three or four days in a row and doesn't bounce back, that's the signal: you're stacking fatigue, chronically underslept, or getting ill. Watch the direction, not one morning's number.
What to do with the score
Readiness only helps if it turns into a decision. Rough guidelines:
High readiness
The body has recovered and is asking for work. This is a day for quality: intervals, tempo, strength, a long session. Don't waste it on an easy jog — use the window.
Moderate readiness
Green light for normal aerobic work. Progress steadily, no heroics. Most of your training days should look like this — and that's exactly right.
Low readiness
Not a reason to panic, but a reason to pull back: easy recovery, zone 1–2, mobility, or an honest rest day. Forcing a hard session on low readiness is a direct route to overtraining and injury. One skipped hard day costs you nothing; an ignored signal costs you weeks.
Where Sport AI Link fits in
The problem with readiness is that there's a lot of data but you need one clear conclusion. That's exactly what Sport AI Link does.
The bot connects to your watch (Garmin, Oura, Whoop, Fitbit), spends a few weeks building your personal baseline, and every morning computes readiness from HRV, resting heart rate, sleep and recent load — with deterministic code, against your own norm, not a population average. The output isn't ten charts but one clear verdict for today: push, cruise, or rest. The code does the numbers; the AI voices the coaching on top — direct, no coaxing.
