What is Activity Detection and how does it work?

Activity Detection is a feature that identifies periods of elevated heart rate and higher-than-average movement, and logs them as Activities in the WHOOP app. Activity Detection can help identify times when you are active or working out, removing the requirement to start and stop an activity or add one after the fact.

Periods of elevated heart rate and movement will be logged as activities if they meet the following criteria:

  • They are at least 15 minutes in length, and
  • The Strain for the resulting Activity is above an 8.

Activities will be automatically logged once Activity Detection determines that your heart rate has returned to and maintained a normal level. This may take around 20 minutes after the end of a workout or activity.

If you are in the midst of (or immediately following) a period of detected activity, you may see an “Analyzing Elevated HR”item appear on the Overview screen in the WHOOP app. This is an indication that your heart rate has been elevated for long enough that an Activity may be detected.

WHOOP will even label the activity if we find that your motion matches one of our 39 supported activities. WHOOP currently supports labeling:
