Polar offers their RS100 Monitor as the next best thing to having your own personal trainer. Polar's "Keeps U Fit - Own Workout Program" offers personal guidance on how hard, how often, and how long you need to exercise to make your personal fitness goals work for you. This helpful feature is also found in the Polar F11 and F55 Fitness Heart Rate Monitors. The Keeps U Fit program is offered free of charge in Polar Fitness Trainer web service.

As with most Polar Heart Rate Monitors, the RS100 lets you monitor your exercise intensity level and use ECG accurate pulse readings to help you take each workout to the next level. The innovative RS100 Polar Heart Monitor may also be used as a stopwatch. OwnCode feature eliminates interference or "crosstalk" from nearby heart rate monitors. The OwnCal feature shows you how many calories burned during every exercise, and even total calorie expenditure with each completed exercise. Backlit digital display allows you to see your progress on the watch face -- even in the dark. Automatically find out your personal heart rate target zones based on your daily physical condition with the Polar OwnZone feature.
