What is a good heart rate recovery?

How fast your heart rate drops after exercise, what’s a good number, and how to use it in your workouts

How to measure it

  1. Do a hard effort of a few minutes, such as an interval at 90% of your maximum.
  2. Note your heart rate the moment you stop.
  3. Walk slowly for one minute and note it again.
  4. The difference is your one-minute heart rate recovery.

Measure it the same way every time, with the same effort and the same cool down, so you can compare. A chest strap reacts faster than a watch.

What the study found

Key study

Slow recovery, higher risk

  • Cohort study
  • 2,428 adults
  • 6 years

Adults who had an exercise test and whose heart rate fell by 12 beats per minute or less in the first minute of recovery were about twice as likely to die in the next six years, after allowing for other risks.

Using recovery in your intervals

Instead of resting for a fixed time, you can rest until your heart rate comes down to a target, such as 60 to 70% of your maximum, so each round starts from a similar place. In Cero, Adaptive HR does this for you, extending the rest by up to the time you choose.
