Training Zones

Understanding Training Zones

  • Training zones refer to different intensity levels at which you can exercise, measured in terms of heart rate.
  • These zones are usually expressed as a percentage of maximum heart rate, which varies by age.
  • The primary training zones are: the aerobic zone, the anaerobic threshold or lactate threshold, and the red line zone.
  • Each of these zones have unique characteristics and benefits, depending on your fitness goals.

The Aerobic Zone

  • The aerobic zone, also known as the ‘fat-burning zone’, typically encompasses 60-70% of your maximum heart rate.
  • Exercising in this zone primarily uses fat as a fuel source, promoting weight management and reducing body fat percentage.
  • This zone aids in improving cardiovascular health, enhancing stamina and endurance.
  • Training in this zone should be sustainable for long durations.

The Anaerobic Threshold

  • The anaerobic threshold, or lactate threshold, is often around 80-90% of your maximum heart rate.
  • In this zone, the body begins to accumulate lactic acid faster than it can be cleared, leading to discomfort or fatigue.
  • Training in this zone encourages the body to improve its ability to metabolise lactic acid and delay fatigue.
  • This zone is typically associated with high-intensity interval training (HIIT).

The Red Line Zone

  • The red line zone represents 90-100% of the maximum heart rate, and signifies extremely high-intensity efforts.
  • This zone should be entered sparingly, due to the intense demand it places on the body and the significant recovery time required.
  • Training in this zone can improve anaerobic power, necessary for short bursts of high-intensity activity.
  • This zone may be targeted by elite athletes preparing for specific competitive events.

Applying Training Zone Principles

  • Monitoring heart rate during exercise can help ensure intensity is kept within the desired training zone.
  • Exercise intensity and duration goals should be aligned with unique fitness or health goals.
  • Regularity and progression over time are crucial for any training regime. Achieving balance by varying between zones can optimise benefits and prevent overtraining.
