Target Heart Rate Calculator
Understanding Heart Rate Zones
Heart rate zones help optimize training intensity. Training in different zones produces different cardiovascular adaptations and calorie burn.
Heart Rate Zones
- 50-60%: Very light, recovery
- 60-70%: Light, fat burning
- 70-80%: Moderate, aerobic
- 80-90%: Vigorous, anaerobic
- 90-100%: Maximum effort
💡 Tips
- Use Karvonen formula for personalized zones
- Train in multiple zones for best results
- Resting HR decreases with fitness
- Monitor HR during exercise for safety
