If you’ve ever wondered whether you should stay in the “fat-burning zone,” push harder, or avoid high intensity altogether, you’re not alone. Fitness advice can feel confusing, especially when different sources seem to contradict each other. The truth is much simpler: your body benefits from a variety of intensities.
Training across different heart rate zones improves endurance, cardiovascular fitness, metabolism, and overall resilience, both physically and mentally. Each level of effort serves a purpose, and learning how to use them together is what creates lasting progress.
