As a moderate or active exerciser, the Polar M61  lets you know  how effective your exercise program is.

The Polar OwnIndex  feature lets you know your current physical condition by running a 5 minute Polar fitness test while at rest. The result, OwnIndex  predicts your maximal oxygen uptake, otherwise known as your maximal aerobic power (VO2max), a common indicator of one's aerobic fitness, from heart rate variability at rest, age, height, weight, sex and physical activity level during the past six months.

By knowing your current physical condition, you'll know how hard or often you should exercise to stay fit. And as you exercise with your Polar M61 over the weeks, you'll be able to see the progress simply by taking the Polar OwnZone Advanced lets you train in both a lower intensity OwnZone Low for easy days or for weight management, and a higher intensity OwnZone High for deeper aerobic conditioning.

If weight management is your goal, the OwnIndex  feature of the Polar M61 shows you the calories burned during the workout. In these products even the percentage of the calories burned from fat rather than carbohydrates is calculated. While Exercise Reminders keep you motivated on your regular fitness program three days after your last exercise session. And if you still need justification to invest in a Polar M61, consider getting one to share with a friend. With the feature You and I, which stores the user profiles and exercise data for two people, both you and your friend can take advantage of the personalized features and measurements with a one single button press.
