Your resting heart rate, or RHR, is how many times your heart beats in one minute while you are at rest. It’s both a gauge of your heart health and a biomarker of aging, it’s one of the simplest and best measures of your health.
A healthy resting heart rate is about 60 beats per minute, but this number varies with age. The normal range for a resting heart rate is between 60 bpm and 100 bpm. Well-conditioned athletes, however, could have a resting heart rate of around 40 bpm. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness.
