sit

the measurement to show your heart rate value on the display. Look at your wrist unit after 2 to 3 minutes. This is your HR
sit

To more precisely calculate your HR
sit
, wear your Polar heart rate monitor for one normal day. Occasionally when you sit
and do not engage in any physical activity for 2-3 minutes, write down your heart rate value. In the evening, calculate the
average value.
