My Fitbit Daily Readiness Score is low. Should I work out?
Below 30, Fitbit’s answer is to prioritise rest and active recovery: gentle movement, not a hard session. In the wide Moderate band you can train, and how hard depends on where in the band you sit and what your other signals say.
What the score is made of.
The Daily Readiness Score now lives in the Google Health app. It combines three things, each compared with your personal baseline: heart rate variability, resting heart rate, and your sleep over the past week.
Google recently changed the formula. It removed the activity component and replaced it with resting heart rate, so the score reflects how your body is responding to what you did, not what you did. It also renamed the labels from low, good and excellent to low, moderate and high.
You need 7 nights of wear before the first score, and Google suggests a month of consistent wear for a fuller baseline. Google notes that one poor night can affect the score, but it often takes several nights of inconsistent sleep to change your recovery state much.
What each range means for today.
| Score | Level | What to do today |
|---|---|---|
| 65–100 | High readiness | Train as planned. Google says you are well recovered and may be ready for peak performance, so this is the day for the hard session. |
| 30–64 | Moderate readiness | Train. Near the top of the band, as planned. Near the bottom, or with one signal off, trim it: intensity a notch down, last hard rep left in the tank. |
| 1–29 | Low readiness | Switch the session: easy aerobic work or mobility, and move the hard day two or three days out. If it stays low for several mornings, recover deliberately. |
Educational, not medical advice. With chest pain, a fever or feeling unwell, rest and see a doctor.
What the score can’t see.
One low morning is noise. A late meal, alcohol or a stressful evening can dent HRV for a night. Google itself points to a sustained rise in resting heart rate over a few days as a reason to reduce training intensity. Read the trend against your own normal.
The Moderate band covers 30 to 64, so the label alone can’t tell a near-high day from a near-low one. The score also can’t see a niggle, a race at the weekend, or what you ate yesterday. A specific pain overrules it. If you feel unwell, rest; for a fever, chest pain or illness, see a doctor.
In studies, training timed to daily HRV readings has matched or beaten a fixed plan, and readiness scores lean on the same signal. px reads your Daily Readiness Score every morning alongside your sleep, HRV, resting heart rate and calendar, and sizes the day from all of it, telling you why.
Questions
What is a good Fitbit Daily Readiness Score?
65 or higher is High readiness. 30–64 is Moderate, which Google describes as typical recovery that can handle a workout. 29 or lower is Low.
Should I work out with low readiness on Fitbit?
Google suggests prioritising recovery through gentle movement, mindfulness or extra rest. An easy walk, ride or mobility session fits; intervals and heavy lifting can wait two or three days.
Why did my readiness score change after an update?
Google changed the calculation. Activity was removed and resting heart rate added, and past scores may be recalculated. The labels also moved from low, good and excellent to low, moderate and high.
How long before I get a readiness score?
You need to wear your device for 7 nights of sleep to set a baseline. Google suggests wearing it consistently for a month for a more accurate one.
