Cardio Recovery chart by age on Apple Watch

Cardio Recovery on Apple Watch is the drop in heart rate after a workout. If your heart rate falls from 150 bpm to 125 bpm, the drop is 25 bpm.

A larger drop usually means your heart rate settled faster after exercise. Age and workout type change the result. So do heat, sleep, illness, medication, and hydration. POTS and dysautonomia can also affect it.

The chart below gives broad reference ranges. It cannot diagnose a heart or autonomic condition.

Apple Watch Cardio Recovery chart by age

Apple Watch users usually look at the first-minute drop after a workout. The ranges below are a practical way to read that number on your watch.

Age	Slower recovery	Typical usable range	Strong recovery
Under 35	Under 13 bpm	13 to 30 bpm	31 bpm or more
35 to 49	Under 13 bpm	13 to 28 bpm	29 bpm or more
50 to 64	Under 13 bpm	13 to 24 bpm	25 bpm or more
65 and older	Under 13 bpm	13 to 20 bpm	21 bpm or more

This is not a clinical percentile table. The number changes with age, fitness, workout intensity, heat, hydration, illness, and medication.

Compare several similar workouts. If the drop stays below 13 bpm, ask a clinician about the pattern. Repeat one low result after you recover. Heat, poor sleep, illness, dehydration, or a hard workout may have changed it.

How Apple Watch measures Cardio Recovery

Apple Watch records how far your heart rate falls after exercise stops. The Fitness app shows the result with the workout. Apple Health stores it under heart metrics.

A steady walk, run, ride, or hike with a clear stop gives a cleaner comparison. Stop-start workouts, interrupted cooldowns, and poor watch contact can change the reading.

Why age changes the chart

Heart-rate recovery tends to slow with age. A 68-year-old and a 28-year-old should not use the same expected range.

Compare similar workouts from your own history. Three runs on the same route tell you more than one run compared with a population table.

What can make Cardio Recovery look worse

Cardio Recovery can look lower for reasons that have little to do with permanent fitness.

Poor sleep
Heat or dehydration
Illness or inflammation
Alcohol
Caffeine timing
A harder workout than usual
Stress
Certain medications
POTS, dysautonomia, or other autonomic conditions

Check the other readings from the same day. A low result means more when resting heart rate also rises. Lower HRV, worse sleep, or a symptom flare add more evidence.

How Body Insights uses this kind of signal

Body Insights is a recovery app that reads Apple Watch data through Apple Health. It shows Cardio Recovery beside sleep, HRV, and resting heart rate. Workouts and recent strain appear with them.

The app can show a Cardio Recovery drop beside a higher resting heart rate and worse sleep. It does not diagnose the cause.

When to worry

Compare Cardio Recovery across similar workouts. Do not use one reading to self-diagnose.

Seek medical care for chest pain, fainting, or severe shortness of breath. Do the same for new neurological symptoms or a sudden loss of exercise tolerance. If recovery stays low across many workouts, tell a clinician. Mention any symptoms that occur with it.

Sources and limitations

Apple Watch Cardio Recovery is a wearable estimate. It is best used as a repeated trend, not a single diagnostic threshold.
