How to Use Metric’s Training Readiness Score: A Step-by-Step Guide

A workout-based readiness score summarizes recent training strain. Its meaning depends on the recorded sessions and the model that carries their load forward; sleep and heart-rate trends add separate context. This guide explains Metric’s calculation, then shows how to find the score and inspect the activity behind it.

What you are setting up

Metric Training Readiness is a workout-based estimate. It uses recorded session duration and heart-rate intensity, with shorter- and longer-term load histories, to summarize accumulated strain. The useful workflow is to read the score, open the recent training behind it, and then check separate recovery context. That connects a quick daily view with records you can investigate.

This guide describes Metric’s controls, checked against its implementation on October 3, 2026. It does not set up Apple’s native Readiness feature. Metric works through authorized Apple Health records, and the current iPhone listing requires iOS 26. Check the App Store listing and the offer shown in your app for compatibility and feature access.

1. Confirm that your workouts reach Apple Health

Record a familiar workout with Apple Watch or another compatible source that writes to Apple Health. After syncing, confirm that the session appears in Health with the expected duration and available heart-rate records. Start with a session you recognize so that you can spot an incomplete or unfamiliar record before interpreting a derived score.

When Metric requests Health access, review the categories relevant to training, including workouts, heart rate, and resting heart rate. If you previously declined access, use Apple Health’s app-permission controls to review it. Permission to read a category does not create missing measurements: the recording device still needs to capture them.

2. Add Training Readiness to Home

1. Open Metric’s Home view and choose Edit Home.
2. If Training Readiness is not already on Home, find it under Available Tiles and use its add control.
3. Arrange the tile where you want it and choose Done.
4. Tap Training Readiness to open Training.

Home is customizable, so the tile’s position can differ from someone else’s screenshot. If it is already visible, you can go straight to opening it.

3. Read the score’s direction

Metric uses a 0–100 scale. Higher readiness corresponds to less modeled workout strain; lower readiness corresponds to more strain in the recorded history. Treat the value and its accompanying summary as a prompt to inspect recent training. It is an estimate from a specific workload model, rather than a measurement of every aspect of physical recovery.

For example, a sequence of demanding workouts can matter more than one isolated session. A quieter period can let carried-forward load fade. The exact result depends on the available records. Avoid expecting a fixed score change from a workout length, or reading a particular number as permission to exercise.

4. Open the activity behind the estimate

In Training, use See activity to open workout history and progress. Review the recent totals and sessions, then inspect a familiar workout. Duration and heart-rate coverage are particularly useful because they help determine Metric’s load estimate. Investigate a missing session or an unexpected total before drawing a conclusion from the score.

Compare the workout sequence with the week you remember. A summary is easier to interpret once you know which sessions it includes and whether their records are complete. The readiness-versus-load guide includes a fictional week to demonstrate that review.

5. Check sleep and heart-rate context separately

Return to your sleep and heart-rate views to review sleep, HRV, and resting heart rate alongside training. These are separate signals in Metric; they do not directly enter its Training Readiness formula. They can still matter when interpreting how you feel, particularly after interrupted sleep or during a week with little recorded exercise.

You can review training, sleep, heart trends, nutrition, and longer-term health patterns within the same app. Compare each view with the records and time period it actually summarizes, and look for agreement or differences between them.

6. Repeat a small, consistent review

1. Check that the recent workout history is complete.
2. Read readiness at a comparable point in your routine.
3. Open Training when a change needs explaining.
4. Review separate recovery context and how you feel.
5. At the end of the week, compare your recorded activity with the plan you intended to follow.

If the score does not fit your week

Start with the records. A newly synced workout can change the estimate, and missing sessions or weak heart-rate coverage can make recorded strain appear lower than your actual effort. Light recorded workload and a high score do not prove full recovery. If the problem is a low or changing value, the troubleshooting guide walks through the relevant checks.

A repeatable review of complete records is more useful than optimizing the number itself. Open the score, inspect the workout history behind it, and check the wider context before interpreting a change. Those steps keep the daily value connected to the information it summarizes.
