What is resting heart rate?
Resting heart rate (RHR) is the number of times your heart beats per minute while your body is completely at rest — typically measured while sitting or lying down after several minutes of inactivity. It reflects how efficiently your heart pumps blood without the added demand of physical activity. See also our calculate Zone 2 Range, Zone 2 Lower Bound & Zone 2 Upper Bound — Zone 2 Heart Rate.
What is a normal resting heart rate?
For adults, a normal resting heart rate is generally between 60 and 100 beats per minute. However, well-trained athletes can have RHRs as low as 40 bpm, which is considered healthy for them. Values consistently above 100 bpm (tachycardia) or below 40 bpm (bradycardia) may warrant medical attention.
What is a good resting heart rate?
A lower resting heart rate generally indicates better cardiovascular fitness. An RHR between 50–60 bpm is considered good for most adults, and anything below 50 bpm suggests excellent or athlete-level fitness. The heart is a muscle — regular aerobic exercise strengthens it so it pumps more blood per beat, needing fewer beats per minute at rest.
How does resting heart rate vary by age and gender?
RHR tends to increase slightly with age as cardiovascular efficiency naturally declines. Women typically have slightly higher resting heart rates than men on average. Fitness level, stress, sleep quality, and medications can all influence where your RHR sits within normal ranges for your demographic.

What factors affect resting heart rate?
Key factors include fitness level, body size, age, stress and anxiety levels, medications (especially beta-blockers), caffeine intake, dehydration, illness, and sleep quality. Improving aerobic fitness through consistent cardio exercise is one of the most effective ways to lower your RHR over time.
What is considered a slow or fast resting heart rate?
A resting heart rate above 100 bpm is called tachycardia and may be caused by stress, dehydration, illness, or an underlying condition. A rate below 60 bpm is called bradycardia — in fit athletes this is normal, but in sedentary individuals it may require evaluation. Always consult a doctor if you're concerned about your heart rate.
How do I measure my resting heart rate accurately?
Measure your RHR first thing in the morning before getting out of bed, or after sitting quietly for at least 5 minutes. Place two fingers on your wrist or neck, count the beats for 60 seconds (or 30 seconds and multiply by 2), and record the number. Avoid caffeine, exercise, or stress before measuring for the most accurate result.
Can exercise lower my resting heart rate?
Yes — regular aerobic exercise such as running, cycling, or swimming is one of the most effective ways to lower your RHR. As your cardiovascular fitness improves, your heart becomes more efficient and requires fewer beats per minute to circulate blood at rest. Most people see noticeable reductions within 4–8 weeks of consistent training.
