how heart rate monitor worksThere is just a single difference between the wrist heart rate monitors and the chest bluetooth hrms  and that is the absence of chest straps in the wrist monitors.

They are much like regular watches with stop watch and calendar function that can be used for tracking the training days. This watch-like function as well as appearance of these monitors adds another dimension in using them.

The stop watch in these monitors is very useful to track the running intervals. For an instance, as the running session begins, the stop watch can be started. After warming up for 10 minutes, the user can go for a 30 second sprint and then for 60 second s of jogging.

The user, during all these activities can turn to the stop watch to have an idea about the current state of the workout.

Weight Training

The stop watch function is useful for weight training as well. The user can track the rest intervals very specifically by using the stop watch.

If the user, for example, wants the rest intervals in a circuit workout to be short, he has the scope of stopping it at the desired time after a set and then again going for the next set.

Heart Rate

There is a sensor on the top and bottom as well as above and below the screen of the wrist monitors. Getting the heart rate with these monitors is quite easy as the user just needs to put the index finger on the bottom and the middle one on the top sensor before keeping steady and waiting for the heart rate to flash on the screen.

These monitors also allow the user to check the heart rate even when he is lifting weights and doing so just needs him to check it in the resting periods.

Since running and carrying out other cardiovascular exercises involve frequent movements, it is not quite easy to check heart rate during such activities. The same goes for cycling and high intensity running also.

So, in such cases the users are suggested to resume the exercise for 30 seconds for checking the heart rate.

Advanced Features

Depending on the variations in grade and model wrist heart rate monitors may contain some advanced features. Caloric expenditure is such a feature.

The user just has to input some information like his weight, age and gender for using the feature. Using all this information the monitor will make an estimation of the amount of calorie the user burns in a workout.

This amount entirely depends not on the kind, but on the intensity of the activity the user is doing.
