Frequently Asked Questions
What are heart rate zones?
Heart rate zones are ranges of heart beats per minute that correspond to different exercise intensities. There are typically 5 zones, each with distinct training benefits.
How is maximum heart rate calculated?
The most common formula is 220 minus your age. For example, a 30-year-old has an estimated maximum heart rate of 190 bpm.
Which zone is best for fat burning?
Zone 2 (60-70% of max HR) is optimal for fat burning. However, higher-intensity zones burn more total calories per session.
