What Is a Good Resting Heart Rate for a 40 or 50 Year Old?

US national reference values for resting heart rate in this age band, why they barely change with age, how wearable resting heart rate differs from a clinic count, and what a higher number is associated with.

For a man aged 40 to 59, the median resting pulse in US national survey data is 68 beats per minute, and half of men fall between 61 and 77. For a woman the median is 71, with half between 64 and 79. Unlike VO2 max or HRV, those figures barely change with age: the average for men was 71 at 20 to 39, 71 at 40 to 59 and 70 at 60 to 79. So there is no separate "normal for 45" or "normal for 55". What does change the meaning of the number is where it sits. In a cohort of middle-aged adults, a resting rate of 70 or above was linked to higher all-cause mortality than a rate under 70, and the same direction held across 46 studies. A wearable's resting figure is also usually a lowest-of-the-day or overnight value, which tends to sit below a seated pulse count like the one in this table.

Resting heart rate percentiles for ages 40 to 59

These come from the US National Health and Nutrition Examination Survey, whose reference sample was 35,302 people of all ages with no condition or medication affecting their pulse. The 40 to 59 band is one group in the source; it is not split by decade.

Why there is no chart by decade

The survey's adult means are almost flat: 71, 71, 70 and 71 beats per minute for men aged 20 to 39, 40 to 59, 60 to 79 and 80 and over, and 76, 73, 73 and 73 for women (National Health Statistics Reports, CDC, 2011). A table that prints a different "normal" for 45 and 55 is inventing a difference the measurements do not show. The resting heart rate by age page makes the same point across all ages.

A wearable dataset agrees on the shape and adds detail. In 92,457 US adults wearing a wrist tracker for a median of 320 days, average resting heart rate rose until about age 50 and then began to fall, women ran higher than men at every age, and 95 percent of men sat between 50 and 80 while 95 percent of women sat between 53 and 82 (PLOS One, 2020). The same study found women of childbearing age had more day-to-day variation in resting heart rate than men, peaking in the early 30s, and that the difference was gone by 50, which the authors connect to changes across the menstrual cycle.

What a higher resting heart rate is linked to in midlife

In 4,091 adults from the general population with an average age of 59 and no known coronary disease, followed for a median of 10.5 years, among the 3,348 not taking heart-rate-lowering medication, each 5 beats per minute higher was associated with 13 percent higher all-cause mortality after adjusting for conventional risk factors and coronary calcium. A rate of 70 or above, against under 70, carried a hazard ratio of 1.68 for death from any cause. It did not predict coronary events (Clinical Research in Cardiology, 2016).

In 2,798 healthy middle-aged employed men followed for 16 years, risk rose 16 percent per 10 beats per minute even after adjusting for measured fitness, and men above 90 had about three times the mortality of men at 50 or below (Heart, 2013). So a high resting rate is not only a stand-in for being unfit. Across 46 studies and 1,246,203 people, each 10 beats per minute went with a relative risk of 1.09 for all-cause mortality, and over 80 against the lowest group with 1.45 (Canadian Medical Association Journal, 2016).

Our resting heart rate desk rates the general link between higher resting heart rate and worse cardiovascular health as Emerging, rates the link with heart failure as Established at about 18 to 19 percent more risk per 10 beats per minute, and rates the type 2 diabetes link as Emerging (resting heart rate and diabetes). These are associations in populations; they do not show that lowering one person's number by a given amount changes their risk by the same amount.

Your watch measures a different resting heart rate

The survey figure is a 30-second count at the wrist after four minutes of sitting. Devices define resting heart rate differently. Garmin uses the lowest 30-minute average in a 24-hour period (Garmin support). Oura reports both an average and a lowest overnight figure from readings every 10 minutes (Oura support). Fitbit uses data from both awake and asleep periods (Google support). A lowest-of-the-day number will tend to sit below a seated count, so a watch reading of 58 and a doctor's count of 66 can both be right.

Against an overnight ECG, resting heart rate is one of the more accurate things a wearable reports: mean absolute percentage error was 1.67 percent for Oura Gen 3, 1.94 percent for Oura Gen 4, 2.71 percent for Polar and 3.00 percent for Whoop, in 13 adults over 536 nights (Physiological Reports, 2025). Our desk still rates consumer wearable resting heart rate accuracy as Uncertain across the full set of devices.
