Heart Rate Zones
Ranges of heart rate used to target different training adaptations.
Heart rate zones divide intensity into ranges based on percentage of max heart rate. Zone 2 (60-70%) builds aerobic base, Zone 3 (70-80%) improves endurance, Zone 4 (80-90%) increases threshold, and Zone 5 (90-100%) develops VO2 max. Training in different zones targets different physiological adaptations.
Examples
- Zone 2: 60-70% max HR (aerobic base)
- Zone 4: 80-90% max HR (threshold)
- Targeting specific adaptations
