CategoriesSports

RHR stands for Resting heart rate, a fitness and exercise abbreviation.

Heart rate measured at complete rest, ideally right after waking, in beats per minute. Most adults fall between 60 and 100, and well-trained endurance athletes often sit in the 40s.

Example: My watch showed my RHR creeping up all week, a sign I needed a rest day.

Usage notes

Wearables track RHR trends because an unusual rise can signal fatigue, illness or poor sleep. Fitness improvements tend to lower it over months. Anyone with symptoms such as dizziness should see a doctor rather than rely on a tracker.
