What does the concept of target heart rate refer to in physical fitness?

Target heart rate is a critical concept in physical fitness, as it designates the heart rate range that individuals should aim to maintain during aerobic exercise to achieve maximum cardiovascular benefits. This range is typically calculated as a percentage of an individual's maximum heart rate, ensuring that the workout is not too easy or excessively intense. When exercising within this optimal heart rate zone, individuals can improve their cardiovascular endurance, enhance aerobic capacity, and promote better overall health.

The target heart rate is important for effective training because it helps individuals gauge their effort level, allowing them to monitor their intensity and adjust as necessary to meet fitness goals. By aiming for this specific range during workouts, individuals can maximize their performance and efficiency in cardiovascular training.
