Zone 2 training is widely touted for longevity, but recent research suggests its benefits may be overstated for time-constrained individuals. While it offers a sustainable entry point for cardiovascular health, high-intensity training remains a more efficient alternative for those with limited time. Consistency and personal preference ultimately outweigh the pursuit of technically optimal exercise protocols.
Key insight: A 2025 review titled 'Much to do About Zone 2' argues that much of the hype is based on elite athletes who train 20+ hours a week, making their specific training adaptations potentially irrelevant for the average person with only two hours of weekly availability.
