i just bought this heart rate monitor a few days ago ive only used it once so far and would like to know more about the heart rate zone options it gives you...is it better to use the fat burning zone or aerobic zone? does it matter?..which one do you guys use?..also after a workout what do you press to see all the info like calories burned ect?
