The 4 colors align with the percentage of your maximum Heart Rate (max HR):
- Light blue zone: ≤70% of max HR
- Dark Blue: 71-80% of max HR
- Light Red: 81-90% of max HR
- Dark Red: 91-100% of max HR
During your session, they help you understand the effort you're putting in. It's up to you to if you aim to push harder or recover better.
Note: Your max HR is calculated initially based on your age and sex. If you already know yours, reach out to your coach to adjust it in the system.
