Enter Recovery Data
Use measured heart rates taken immediately after exercise and during the next minutes of recovery.
Formula Used
Recovery Drop at 1 Minute = Peak Heart Rate − Heart Rate at 1 Minute
Recovery Drop at 2 Minutes = Peak Heart Rate − Heart Rate at 2 Minutes
Heart Rate Reserve = Peak Heart Rate − Resting Heart Rate
Reserve Restored % = (Recovery Drop ÷ Heart Rate Reserve) × 100
Predicted Max Heart Rate = 220 − Age
Score = ((Drop1 × 0.45) + (Drop2 × 0.35) + (Drop3 or Drop2 × 0.20)) ÷ Reserve × 100
These formulas provide general fitness guidance. They do not diagnose disease, replace medical evaluation, or account for medication effects.

FAQs
1. What is recovery heart rate?
It is the speed at which your pulse falls after exercise stops. Faster recovery usually reflects better cardiovascular conditioning and efficient autonomic response, though results still depend on effort, heat, hydration, sleep, and medications.
2. Why are one-minute and two-minute drops important?
They show how quickly your body starts returning toward baseline. The first minute often reflects immediate recovery, while two-minute values help show whether the downward trend continues strongly after hard effort.
3. Is a larger pulse drop always better?
Usually, a larger drop is favorable after comparable effort. However, context matters. A light session may create smaller changes, and unusual symptoms should never be judged by a calculator alone.
4. Can I use smartwatch readings?
Yes, if the device records reliably during recovery. Chest straps often provide steadier data during intense sessions, while wrist sensors can lag during motion or sweat-heavy exercise.
5. Why does the calculator use age-based maximum heart rate?
The age estimate gives a simple reference point for training context. It is only an estimate, not your true measured maximum, because individual heart rate responses vary widely.
6. What can slow recovery heart rate?
Heat, dehydration, poor sleep, illness, overtraining, stress, medication effects, and very intense intervals can all delay pulse recovery. Compare results over time under similar conditions for better insight.
7. Should I enter the three-minute value?
It is optional, but useful. A third reading adds trend depth, improves the weighted score, and can show whether recovery continues steadily after the early post-exercise phase.
8. Is this calculator medical advice?
No. It is an educational fitness tool. Seek professional care for chest pain, fainting, unusual shortness of breath, palpitations, or concerns about abnormal heart rate behavior.
