Understanding Strain Metrics
Strain Scale (0-21)
WHOOP uses a proprietary logarithmic scale for strain:
| Range | Level | Description |
|---|---|---|
| 0-9 | Light | Low cardiovascular load |
| 10-13 | Moderate | Sustainable daily activity |
| 14-17 | High | Significant workout |
| 18-21 | Overreaching | Very high strain, recovery needed |
Heart Rate Zones
| Zone | Name | Description |
|---|---|---|
| Zone 0 | Rest | Resting heart rate |
| Zone 1 | Low | Light activity, warm-up |
| Zone 2 | Moderate | Fat-burning, endurance |
| Zone 3 | Vigorous | Cardio training |
| Zone 4 | Hard | Peak performance |
| Zone 5 | Max | Maximum effort |
Zone durations are returned in milliseconds.
Energy (Kilojoules)
Energy expenditure measured in kilojoules.
To convert to calories:
calories = kilojoules / 4.184
For example: 1800 kJ ≈ 430 calories
