Zone zero exercise involves very gentle physical activity performed at a heart rate below 50-60% of maximum, allowing comfortable conversation throughout. It contrasts with high-intensity workouts by emphasizing slow, effortless movement such as gentle walking, easy yoga, or light household tasks. This approach is accessible for older adults, those recovering from injury, or people managing stress, offering health benefits like improved circulation, blood sugar regulation, mental wellbeing, and reduced cardiovascular risk. It also supports recovery for athletes and helps sustain consistent exercise habits by lowering barriers to activity. While zone zero alone does not build high fitness levels needed for endurance events, it serves as a foundational or standalone health practice. The concept remains debated in sports science but has gained popularity for its simplicity and inclusivity, encouraging movement without pressure or specialized equipment. Zone zero exercise addresses risks associated with prolonged sedentary behavior and promotes gradual, sustainable physical activity for long-term health.
