My Ultrahuman Recovery Score is low. Should I train or rest?
Usually train, but adjust. Ultrahuman counts above 85 as optimal and 67 to 85 as high, but your own usual range matters more. Below it, trim the session or swap it for easy aerobic work; save rest for a run of low days.
What the score is made of.
Ultrahuman’s Recovery Score, shown in the app as Dynamic Recovery, is a number from 0 to 100 that sums up how close your body sits to its own rested baseline. Higher means your readings are closer to your rested pattern.
Five contributors feed it, per Ultrahuman: the Sleep Index (how long and how efficiently you slept, your sleep stages and timing), overnight resting heart rate against your baseline, HRV Form (how far last night’s HRV departs from your baseline), skin temperature against your usual overnight level, and the Stress Rhythm Score, which follows how heart rate and HRV move through your day.
The first four are set by the time you wake. Stress Rhythm keeps reading, so the score can move by up to ten points either way during the day, and Ultrahuman says naps, breathwork and non-sleep deep rest can lift it. The app names the contributor driving your score.
What each range means for today.
| Score | Level | What to do today |
|---|---|---|
| Above 85 | Optimal | Train as planned. Your readings sit close to your rested baseline, so the hard session is on. A stretch of these is the time to add a little load. |
| 67–85 | High | Train as planned if this is your usual range. If it’s well below where you normally sit, train trimmed: same session, intensity a notch down, last hard rep left in the tank. |
| Below 67 | Lower (no band name published) | Read it against your own range. Well below your normal: switch to easy aerobic or mobility work and move the hard day two or three days out; several low days with short sleep and hard training: 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.
Your own range matters more than the bands, and Ultrahuman makes the same point: one score can be a poor day for someone who usually sits high and a good one for someone who usually sits lower. One low morning is noise; a run of low scores is the signal. In one small trial, runners whose hard days were set by their morning HRV improved their top running speed more than those on a fixed plan.
Because the score moves through the day, read it each morning and decide then. A nap can lift the afternoon number, but last night’s HRV and resting heart rate are already set. The score also can’t see a niggle or a hard day coming, and a specific pain overrules a good score.
A shift in skin temperature or resting heart rate is a pattern to notice, not a diagnosis: if you feel unwell, have a fever or chest pain, see a doctor. px reads your Ultrahuman Recovery 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 Ultrahuman Recovery Score?
Ultrahuman counts above 85 as optimal and 67 to 85 as high, but says your own range is the more useful comparison.
Why does my Ultrahuman Recovery Score change during the day?
Four contributors are set overnight, but Stress Rhythm keeps reading after you wake and can move the score by up to ten points either way. Ultrahuman says naps, breathwork and non-sleep deep rest can lift it.
Should I skip training if my Ultrahuman recovery is low?
Not automatically. Ultrahuman describes a low score as a reason to look, not an instruction. Check which contributor is low, read it with how you feel, and usually trim or switch the session. Take a persistent low run with symptoms to a doctor.
Is the Recovery Score the same as Cardio Recovery?
No. Ultrahuman’s Cardio Recovery measures how fast your heart rate falls in the minutes after exercise. The Recovery Score is an overnight and all-day summary of how ready you are.
px reads your Ultrahuman Recovery Score every morning.
Alongside your sleep, HRV, resting heart rate and calendar, so the day is sized from all of it, not one number. You get the plan and the reason.
