During the initial stage of exercise, what intensity should aerobic activity begin?

Beginning aerobic activity at an intensity of 40-60% of heart rate reserve (HRR) during the initial stage of exercise is appropriate because this range is often considered a moderate level of effort. It allows individuals to gradually adapt to physical activity without overexertion, making it suitable for beginners or those returning after a break from exercise. Starting at this intensity helps minimize the risk of injury and burnout while promoting cardiovascular endurance and overall fitness improvement.

This range encourages individuals to develop a solid foundation, focusing on correct form, breathing, and stamina. It also aligns with guidelines set by health organizations for safe exercise initiation, ensuring participants can comfortably engage in aerobic activities while still reaping the benefits of improved cardiovascular health.
