Heart Rate Training Zones

Understanding different heart rate zones for optimal training

Zone 1: Recovery

50-60% Max HR

Purpose: Active recovery, warm-up, cool-down

Benefits: Promotes recovery, improves circulation, builds aerobic base

Feel: Very easy, can hold conversation easily

Duration: 20-90 minutes

Zone 2: Aerobic Base

60-70% Max HR

Purpose: Base building, fat burning, endurance

Benefits: Builds aerobic capacity, burns fat efficiently

Feel: Easy, comfortable conversation pace

Duration: 30-120+ minutes

Zone 3: Aerobic

70-80% Max HR

Purpose: Aerobic development, tempo training

Benefits: Improves aerobic power and efficiency

Feel: Moderate effort, short phrases possible

Duration: 20-60 minutes

Zone 4: Lactate Threshold

80-90% Max HR

Purpose: Lactate threshold, race pace training

Benefits: Increases lactate buffering, race performance

Feel: Hard effort, difficult to speak

Duration: 8-40 minutes

Zone 5: VO2 Max

90-100% Max HR

Purpose: Maximum oxygen uptake, power development

Benefits: Increases VO2 max, anaerobic power

Feel: Very hard, cannot speak

Duration: 3-8 minutes

Heart Rate Monitoring Tips

Timing

Measure resting HR first thing in the morning before getting out of bed

Factors

Heat, humidity, caffeine, stress, and illness can affect heart rate

Trends

Look for patterns and trends rather than single measurements

Consultation

Consult a healthcare provider for unusual heart rate patterns

Heart Health Insights

Understanding your cardiovascular health and training optimization

Resting Heart Rate

Excellent Athletes: 40-60 bpm
Good Fit: 61-70 bpm
Average Normal: 71-85 bpm
Poor High: 86+ bpm

Lower resting heart rate typically indicates better cardiovascular fitness

Heart Rate Variability

What is HRV? The variation in time between heartbeats

Higher HRV: Better recovery, less stress, good fitness

Lower HRV: Overtraining, stress, illness, fatigue

Monitoring: Use specialized HRV devices for accurate measurement

Training Adaptations

Improved Efficiency: Heart pumps more blood per beat
Lower Resting HR: Heart works less at rest
Faster Recovery: HR returns to baseline quicker
Higher Max HR: Can achieve higher intensities

Warning Signs

Chest pain or discomfort during exercise
Unusually high resting heart rate
Irregular heartbeat or palpitations
Dizziness or shortness of breath

Important: Consult a healthcare provider if you experience any warning signs
