Which of the following best describes the concept of a "target heart rate"?

The concept of a "target heart rate" refers to the desired range of heart rates during exercise that an individual aims to reach to achieve optimal cardiovascular benefits. This range is typically based on a percentage of the person's maximum heart rate, which is influenced by age, fitness level, and specific exercise goals. The target heart rate helps individuals ensure that they are exercising at an intensity level that is both safe and effective for improving cardiovascular endurance and overall fitness.

Maintaining the heart rate within this range during aerobic activities allows for improved heart function, increased aerobic capacity, and enhanced calorie burning while minimizing the risk of overexertion. It's an important aspect of exercise programming, particularly in designing workouts that are tailored to an individual's fitness level and goals.
