Resting Heart Rate Guide
See what your resting heart rate says about your cardiovascular fitness. Compared live against age and sex norms, with the science behind every label.
A low resting rate is normal and healthy in trained athletes. This flags it so a sub-50 bpm reading is not read as a warning.
Bands are illustrative fitness categories, not a clinical diagnosis. The medical normal range is 60-100 bpm; lower is generally fitter, but a single reading can shift several beats with caffeine, stress, sleep, or hydration.
Why a lower resting rate tends to mean lower risk
In a large meta-analysis (Zhang 2016, CMAJ), every 10 bpm higher resting heart rate was associated with about a 9% higher all-cause mortality risk (relative risk 1.09, 95% CI 1.07-1.12) and an 8% higher cardiovascular mortality risk (RR 1.08, 95% CI 1.06-1.10). The relationship was linear, and risk rose even within the “normal” 60-100 bpm range. This is a population association, not a personal prediction, and the tool does not convert beats into years of life. Women average a few beats per minute higher than men (roughly 3-7 bpm in large cohorts), which this tool accounts for.
Frequently asked questions
What is a normal resting heart rate?
For adults, 60–100 bpm is considered normal by medical standards. However, a truly healthy RHR is typically 55–75 bpm. Fit individuals often have RHR of 45–60 bpm. Elite athletes can be as low as 35–45 bpm.
What causes a high resting heart rate?
Common causes: dehydration, poor sleep, stress, caffeine, alcohol, lack of exercise, illness/infection, medication, and overtraining. A sustained increase of 5+ bpm above your baseline warrants attention.
How can I lower my resting heart rate?
Regular aerobic exercise (3–5x/week, 30+ minutes) is the most effective method. Other factors: adequate sleep, stress management, proper hydration, limiting alcohol and caffeine, and maintaining healthy body weight. Improvements are typically visible within 4–8 weeks.
Does resting heart rate change with age?
RHR tends to stay relatively stable through adulthood but may increase slightly after 60. The bigger factor is fitness level: a fit 60-year-old can have lower RHR than a sedentary 25-year-old.
