This monitor is a fitness fanatic’s best friend. Not only will it tell you calories burned in a workout logging up to 99 training sessions but it will also tell you if the focus of your workout is burning fat or improving fitness. A visual display will show you if you’re veering toward fat burning or fitness improvement. Other features include: age-based target heart rate zone automatically calculated and displayed as either beats per minute or as a percentage of your maximum heart rate; the option to manually input your target heart rate zone; visual and audible alarms that alert you when you’ve left your target zone; water resistance up to 30 meters; a graphical target zone indicator; and weekly history of your training data. You can also upload your data to your computer with Polar’s FlowLink USB connector.
