Answer:
Two of the devices for measuring heart rate activity are the activity monitor or smart watch and chest straps.
Explanation:
Activity monitors are economical, do not take up too much space and their battery is long lasting. Using a Fitbit, an Apple Watch, a Garmin allows you to measure your heart rate at any time of the day.
The chest strap is economical and works by reading the electrical signal that the body produces when the heart contracts. They are more precise than smart watches, but they have some disadvantages, such as the discomfort they cause because they are fixed around the sternum, it is a bit difficult to adjust while moving, etc.
