If running is what you do to stay in shape, the RS100 will give you valuable feedback that can help improve your fitness or lose those last few pounds. It combines all the heart rate features you need with the stopwatch you're used to. Track your average heart rate and time for each lap, so you can integrate heart rate easily into your fitness running program.

In order to reach your fitness goals, you need to exercise at the right intensity. The Polar RS100 wrist heart rate monitor helps you to easily and accurately measure your heart rate to help you get to just the right intensity or your exertion level. This basic HRM features added stopwatch and time-of-day watch features as well as extra-large digits for easy readability. The Time in Target Zone feature calculates the amount of total exercise time spent in your personal target zone. You can use this feature together with the Total Exercise Time to determine the effectiveness of your exercise program.

The RS100 displays heart rate as beats per minute (beats per minute) and as a percentage of the maximum heart rate. The Target Zone feature can be set manually or automatically (for age/weight), and the RS100 provides visual and auditory alarms when you've moved away from the zone. Other features include dual time zone, alarm with snooze, and water resistance to 50 meters.

It's a great choice for using in large groups, where other exercisers might be using wireless training gear that could interfere with your own signal. The RS100's coded transmission prevents crosstalk with other monitors so you'll get a personalized workout--even in a class environment. It also includes the following exclusive Polar features:

• Polar OwnCal: This feature shows your energy expenditure during one exercise session as well as your accumulated kilocalories during several exercise sessions. You can set daily and weekly exercise goals in terms of calorie expenditure with the OwnCal feature. Because the OwnCal tracks both the energy expenditure during one exercise session and the accumulated kilocalories during a longer time e.g. one week, it helps in achieving both short term and long term goals.
• Polar OwnZone: This feature guides you through an appropriate warm-up routine and automatically determines a safe and effective exercise heart rate zone--your OwnZone--while taking into account your current physical condition.

About Polar
The first EKG accurate wireless heart rate monitor was invented by Polar back in 1977 as a training tool for the Finnish National Cross Country Ski Team. The concept of "intensity training" by heart rate swept the athletic world in the eighties. By the 1990s, individuals were looking to heart rate monitors not only for performance training needs, but also for achieving everyday fitness goals. Today, the same concept of heart rate training is being used by world-class athletes as well as everyday people trying to lose weight. Polar is the leading brand among consumers, coaches, and personal trainers worldwide and the company is committed to not only producing the best products, but also being the leading educator on the benefits of heart rate based exercise.
