Training Readiness Score: What It Is, How It's Calculated, How to Use It

A Training Readiness Score is a single number — usually 0 to 100, sometimes a TRAIN / ADAPT / RECOVER label — that tells a coach whether their client's body is prepared to handle today's planned session. Whoop calls it Recovery. Garmin calls it Training Readiness. Oura calls it Readiness. They're all solving the same problem: collapse 5–7 physiological signals into one number a human can scan in two seconds.

For a personal trainer with a roster of clients, the readiness score is the single most useful piece of data you can put at the top of a dashboard. It is the answer to "what session should I run today?" before the client walks in the door.

The four inputs that actually matter

Every credible readiness algorithm we've seen — academic, commercial, or built in-house — uses some weighted combination of the same four signals.

1. HRV deviation from baseline (weight ~35%)

Today's HRV compared to the client's 30-day rolling baseline. This is the most sensitive signal in the model. A 10%+ drop pulls the score down meaningfully; a sustained drop across 2+ days pulls it down further.

2. Sleep (weight ~25%)

Total hours last night, with a small modifier for consistency over the last 7 days. Under 5h drops the score sharply. 5–6.5h moderately. 6.5h+ is neutral.

3. Resting heart rate deviation (weight ~20%)

A slower-moving signal. A 5+ bpm rise above baseline almost always means accumulating fatigue or oncoming illness, and pulls the score down even when HRV and sleep look fine.

4. Acute workload / ACWR (weight ~20%)

How much load the client has absorbed in the last 7 days relative to the rolling 28-day average. ACWR above 1.3 pulls the score down regardless of how well-recovered the client looks on a single morning — because the body has not yet finished processing yesterday's work.

What the number means in practice

• 80–100 — TRAIN. Green light. Run the session as programmed, push top sets to RPE 8–9.
• 60–79 — ADAPT. Keep the structure. Drop one working set per main lift, cap RPE at 7–7.5.
• 40–59 — RECOVER. Switch to skill work, mobility, or Zone 2. No top-end intensity.
• Below 40 — REST. Active recovery only, or cancel and reschedule.

What we see in the data

Anonymized across the CoachPulse client base: roughly 55% of mornings are TRAIN, 30% are ADAPT, and 15% are RECOVER or REST. That ratio matches well-trained athletic populations. The interesting finding: clients whose coaches actually adjusted the session on ADAPT days (rather than pushing through) showed measurably faster HRV baseline growth over the following 8 weeks. The cost of pulling back on an ADAPT day is zero. The cost of ignoring it is a slow erosion of the chronic baseline.

Common ways the score is misused

Reading today's number in isolation

A single low-readiness morning means very little. Two in a row matters. Three in a row demands an action — usually an unscheduled deload day.

Letting clients self-coach with it

When clients see a low readiness number, they tend to skip the session entirely. That's overcorrection. The readiness score is meant to modify the session, not delete it. ADAPT is a real workout, not a rest day.

Using it as a motivation tool

Don't show the raw score to clients who are anxious about training. For some clients it's empowering; for others it becomes another number to obsess over. The score is primarily a coach-facing tool.

Building it for a roster

Calculating readiness for one client is doable in a spreadsheet. For a roster of 10–30 clients, with different baselines, different wearables, and different program phases, it stops being practical to compute manually. That is exactly what CoachPulse calculates and surfaces: one TRAIN / ADAPT / RECOVER signal per client, every morning, with the underlying HRV, sleep, RHR, and ACWR visible if you want to dig in.

The bottom line

A readiness score is not a verdict on the day. It's a decision aid that compresses everything you'd want to know about a client's recovery into a number you can read in the time it takes to make coffee. Coaches who use one consistently end up making fewer obviously-wrong programming calls — and over a year, that's the difference between a client who progresses and one who plateaus.
