Understanding Your Heart Rate Training Zones
The five heart rate training zones, plus what they are used for, according to Alex:
Zone 1: Very light intensity (50-60% of max heart rate): This zone is primarily for warm-up, cool-down, and recovery exercises. It helps increase blood flow, improve cardiovascular health, and promote active recovery.
Zone 2: Light intensity (60-70% of max heart rate): Training in this zone enhances endurance and aerobic capacity. It promotes fat burning and improves the efficiency of oxygen utilization in the body.
Zone 3: Moderate intensity (70-80% of max heart rate): This zone improves cardiovascular fitness, enhances endurance, and increases lactate threshold. Training here helps improve performance for longer-duration exercises.
Zone 4: Difficult intensity (80-90% of max heart rate): Training in this zone increases anaerobic fitness, improves speed, and builds muscle strength and power. It’s beneficial for interval training and improving your race pace.
Zone 5: Maximum intensity (90-100% of max heart rate): This zone is for maximum effort and high-intensity interval training (HIIT). Training here improves peak performance and develops speed and power.
