WHOOP Recovery Score: Green, Yellow and Red Explained

The recovery ranges

WHOOP recovery is a personalized readiness estimate from 0% to 100%. The color answers a simple question: how prepared does your recent physiology look for strain today?

WHOOP recovery	What it means	Normal training response	Important caveat
Green: 67-100%	Your overnight signals are favorable relative to your baseline	Good day for planned hard training when you also feel ready	Green is permission, not a requirement to chase maximum strain
Yellow: 34-66%	Your signals are near baseline or show some unresolved stress	Usually continue the plan; reduce intensity when warm-up or symptoms disagree	Yellow is common and does not automatically mean take a rest day
Red: 0-33%	Your physiology shows substantial stress relative to baseline	Favor recovery or a lighter session, especially with illness, sleep loss, or consecutive red days	One isolated red score can be noise; use the trend and how you feel

The score is guidance, not a diagnosis. Use it with symptoms, training context, and the quality of your warm-up. My live WHOOP page shows the current score alongside HRV, resting heart rate, sleep, and recent trends.

What goes into a WHOOP recovery score?

WHOOP compares overnight measurements with your rolling personal baseline. That personalization is important: a good HRV or resting heart rate is not one universal number shared by every athlete.

Heart rate variability

Heart rate variability, or HRV, measures variation in the time between heartbeats. WHOOP uses overnight HRV as a major signal of autonomic nervous-system state. A value above or below your normal range is more useful than comparing it with somebody else’s number.

Resting heart rate

Resting heart rate can rise when the body is dealing with training stress, illness, alcohol, dehydration, or poor sleep. A lower value is not automatically better in isolation; the useful comparison is your recent baseline and the surrounding context.

Sleep

Sleep performance describes how much of WHOOP’s calculated sleep need you achieved. More time asleep can support recovery, but a long night does not guarantee a green score when HRV, resting heart rate, or respiratory rate move in the wrong direction.

Respiratory rate

Respiratory rate is usually stable for an individual. A meaningful overnight change can be a useful warning signal, especially when it appears with symptoms or other abnormal measurements.

How to use a green recovery

A green score means the overnight signals WHOOP uses look favorable relative to baseline. If a hard lifting session, run, or demanding practice is already in the plan and your warm-up agrees, green supports doing it.

It does not mean every green day should become a maximal day. Training still needs easier sessions, skill work, and planned progression. Treat the score as context for the plan rather than a replacement for the plan.

How to use a yellow recovery

Yellow is a normal training state. It often means the body is managing recent strain, stress, or imperfect sleep without showing the stronger warning represented by red.

For a normal yellow day, I begin the planned session and use the warm-up as a second check. If movement, heart rate, or symptoms feel wrong, I reduce the session. If the warm-up feels normal, yellow alone is not a reason to stop.

How to use a red recovery

Red deserves attention when the score matches the rest of the evidence. An elevated resting heart rate, suppressed HRV, unusual respiratory rate, very short sleep, illness symptoms, or several red days in a row all strengthen the case for reducing strain.

One unexpected red day can happen. Look at why the score changed and whether your body agrees before making a major decision.

When to trust the score most

• Your symptoms and the WHOOP signals point in the same direction.
• Respiratory rate or resting heart rate moved meaningfully away from baseline.
• Poor sleep, alcohol, illness, or a major training load explains the change.
• Red recovery repeats across consecutive days.

When to give the score less authority

• It is one isolated result with no supporting change in the underlying measurements.
• A race, competition, or planned event matters more than optimizing one day’s training readiness.
• The warm-up feels normal and the score is yellow rather than red.
• Sensor fit, missing sleep, or an unusual recording may have affected the data.

Improve the inputs, not just the color

The useful goal is better recovery habits, not collecting green badges. The highest-value levers are consistent sleep timing, adequate sleep, hydration, sensible training progression, and reducing behaviors that reliably disrupt your overnight measurements.

Watch multi-day trends. A single score creates a reaction; repeated patterns help you learn which behaviors actually affect your recovery.

Bottom line

Green is 67-100%, yellow is 34-66%, and red is 0-33%. The best decision comes from combining that color with the underlying measurements, your recent training, symptoms, and the warm-up in front of you.

WHOOP is most useful as a feedback loop. It should make your decisions more informed, not make them for you.
