The heart rate alert notifies you if 

your heart rate exceeds or drops 

below a specific number of beats 

per minute (bpm).
Heart rate alerts can also notify 

you if your heart rate exceeds 

or drops below a certain heart 

rate zone—a range of beats 

per minute. The five commonly 

accepted heart rate zones can 

help you determine the intensity 

of your workout. For more

rate zones, see
