You can measure your resting heart rate by counting your heartbeats per minute while you are calm and sitting still.
The rule
Resting heart rate is the number of times your heart beats in one minute when you are at rest.
Let's understand it simply
Imagine your heart is like a water pump. Even when you are sitting quietly, it keeps pumping blood to every part of your body. The number of times it pumps (beats) in one minute when you are calm is called your resting heart rate. It tells you how hard your heart is working when you are not doing any activity.
How it works
Sit quietly for at least 5 minutes. Do not talk or move much.
Find your pulse (heartbeat) on your wrist or neck using your index and middle fingers.
Press gently until you feel the regular beating.
Use a watch or phone timer. Count the number of beats you feel in 60 seconds (1 minute).
The number you get is your resting heart rate, in beats per minute (bpm).
How to measure your resting heart rate
Sit quietly for 5 minutes
Find your pulse on your wrist or neck
Count beats for 60 seconds
That number is your resting heart rate (bpm)
Where you see it in real life
At the doctor’s clinic → Nurse checks your pulse to see if your heart is healthy.
During sports practice → Coaches check players’ heart rates before and after exercise.
At home → People with heart problems check their resting heart rate daily.
In yoga or meditation → Teachers may ask you to check your pulse before and after relaxation.
Why it matters
A normal resting heart rate shows your heart is working well.
If your rate is too high or too low, it can signal a health problem.
Athletes often have a lower resting heart rate, showing a strong heart.
Doctors use this number to track your heart health over time.
Common mistakes
Using your thumb to feel the pulse (it has its own pulse, which can confuse you).
Counting for only 10 or 15 seconds and forgetting to multiply to get the full minute rate.
Measuring right after running or climbing stairs (not truly 'resting').
Remember it
Count your pulse for one full minute while sitting calm—this is your resting heart rate.
Check yourself
Why should you not use your thumb to check your pulse?
Because the thumb has its own pulse, which can confuse your count.
What should you do before measuring your resting heart rate?
Sit quietly for at least 5 minutes to let your heart settle.
If you count 18 beats in 15 seconds, what is your resting heart rate?
72 bpm (18 × 4 = 72), because there are four 15-second intervals in a minute.
Quick recap
Resting heart rate is your heartbeats per minute when calm.
Measure after sitting quietly for at least 5 minutes.
Use your fingers (not thumb) to feel the pulse.
Count for a full 60 seconds for accuracy.
A normal adult resting heart rate is usually 60–100 bpm.
