This heart rate Monitor tracks the calories you burn by keeping track of your heart rate, age and weight.
You wear a monitor around your chest that measures your heart rate, constantly updating the figures and sending the information to your Polar watch.
Using this with the Calorie Journal is great for letting you know when you need to step up your workout at the end of the day to burn off those extra calories from lunch at the office. The best part is that its comfortable enough to wear all day and all night; and discrete enough that no one ever knows that you have it on.
I can even wear it with my little black dress when I go dancing!
