Chest strap monitors provide the most accurate results when measuring heart rate. Other devices, such as smart watches, can also track and measure heart rate.
If a person does not have access to any devices, they can track their heart rate manually. According to the National Health Service in the United Kingdom, the best way to measure heart rate manually is to find the pulse in the wrist or neck.
To find the pulse at the wrist, people should place their index and middle finger at the base of the thumb on the inside of the wrist. To find the pulse in the neck, people should place their index and middle finger at the side of the throat, underneath the jaw and beside the windpipe.
Then, they can set a timer for 60 seconds and count the heartbeats. Alternatively, they can count the heartbeats for 30 seconds and multiply the number by two.
