Does Zone 2 training live up to all the hype?

Zone 2 training is gaining attention across Canada for its claimed benefits in fitness programs. As the fitness landscape continuously evolves, it's crucial to discern the practical benefits of such trends.

Zone 2, known for its moderate-intensity efforts keeping the heart rate at 60-70% of its maximum, is praised for enhancing endurance, metabolic health, and recovery. This blog will explore the science of Zone 2 training, discuss its benefits and potential drawbacks, and determine its true value in your fitness regimen.

The Benefits of Zone 2 Training

1. Enhanced Fat Utilisation and Endurance:

Common in Canadian endurance sports, Zone 2 training is effective in increasing the body's ability to burn fat over carbohydrates. This not only preserves glycogen stores for intense activities but also enhances overall endurance and performance.

2. Improved Mitochondrial Health:

Regular Zone 2 exercises boost mitochondrial density and efficiency, critical for energy production in our cells. This benefit is linked with better aerobic capacity and potentially longer life spans.

3. Optimised Recovery and Injury Prevention:

The moderate intensity of Zone 2 allows for longer sessions with reduced fatigue and injury risk, making it perfect for recovery days. It’s an excellent strategy to strengthen the aerobic foundation while reducing stress on the body, which is particularly important given the varied climate and conditions in Canada.

4. Enhanced Lactate Clearance:

Training in Zone 2 improves the body’s ability to clear lactate, helping Canadian athletes maintain performance during high-intensity bursts, crucial in sports like hockey and cross-country skiing.

5. Supports Longevity and Cardiovascular Health:

Beyond athletic performance, Zone 2 training contributes to cardiovascular health, evidenced by improved heart rate variability and a lower resting heart rate, which are essential for long-term health outcomes.



Considerations and Potential Drawbacks

1. Perceived Lack of Intensity:

Some may find Zone 2 training less challenging due to its lower intensity, which could impact motivation, especially among those who prefer high-energy workouts.

2. Time Commitment:

The lower intensity necessitates longer sessions to achieve significant results, which could be challenging for those with limited time— a common issue for busy Canadians balancing work and personal life.

3. Measurement Accuracy:

Maintaining accurate Zone 2 intensity can be difficult without proper equipment. Regular monitoring is essential to ensure training effectiveness.

4. Balanced Training Needs:

While Zone 2 training offers numerous benefits, incorporating a variety of training intensities is crucial for comprehensive fitness, including high-intensity sessions to promote overall fitness and strength.



Incorporating Zone 2 Training into Your Weekly Routine

1. Assess Your Fitness Level:

Begin by evaluating your current fitness status and training volume. This is especially important for those new to regular exercise.

2. Determine Zone 2 Intensity:

Calculate your Zone 2 heart rate by subtracting your age from 220 and multiplying by 0.6 and 0.7. Using a heart rate monitor can ensure accuracy during workouts.

3. Schedule Regular Sessions:

Include 3-4 Zone 2 sessions weekly, each lasting 45 to 60 minutes. Spreading these sessions out can aid recovery and maintain consistency.

4. Choose Suitable Activities:

Start with activities you enjoy such as brisk walking, cycling, or slow jogging—ideal for maintaining a Zone 2 heart rate.

5. Combine with Other Training Forms:

Maintain a balanced regimen by including strength, flexibility, and high-intensity cardio exercises on other days.

6. Monitor and Adjust:

Observe your body's response to Zone 2 training and adjust the intensity or duration as needed.

7. Gradual Progression:

As your fitness improves, gradually increase the duration or intensity of Zone 2 workouts to continue challenging your body and enhancing your fitness and endurance.


In conclusion, Zone 2 training is a versatile and beneficial element of a comprehensive fitness program, particularly for those looking to improve endurance, recovery, and metabolic health. By integrating this training style into your routine, you contribute to better overall health and fitness longevity, a vital aspect of staying active and healthy.
