Faster OwnZone® (basic)
Individual determination of your optimal target heart rate limits.
The Polar OwnZone® feature determines an individual and safe light to moderate intensity exercise zone (65-85% HRmax). Polar Heart Rate Monitors use multiple methods for determining your OwnZone®. The primary method is to measure your heart rate variability during the warm-up period before exercising. It 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.

Alternatively, the Polar Heart Rate Monitor will automatically calculate OwnZone® limits based on your age-predicted maximum heart rate (220 minus age).

The OwnZone® corresponds to 65-85 % of the maximum heart rate. Exercise at the lower end of this intensity level can be conducted for extended periods safely and often yields the best results for weight control, while exercise at the upper end of this intensity produces the best results for improving cardiovascular fitness. When you exercise, you can also use your heart rate monitor's latest saved OwnZone® limits. However, you should recalculate your OwnZone® at the beginning of your workout whenever you change exercise environment and/or exercise mode or if your psychological state changes when feeling stressed or depressed, for instance.

Polar Heart Rate Monitors are equipped with a faster OwnZone® feature that determines personal heart rate limits for an exercise session in 5 minutes.
