What is the target heart rate zone for moderate-intensity exercise?

The target heart rate zone for moderate-intensity exercise is typically defined as 50-70% of an individual's maximum heart rate. This range is recognized as effective for improving cardiovascular fitness while still being achievable for most individuals. Moderate intensity means that the exercise should elevate the heart rate to a level where a person can still talk but not sing during the activity.

Exercising within this heart rate zone can help to build endurance and improve overall heart health without overexerting the individual. It provides a balance between exertion and sustainability, allowing for longer durations of exercise which is essential for maintaining good health and fitness levels. This zone is often recommended for those who are looking to engage in regular physical activity as part of a healthy lifestyle.

In contrast, lower percentages like those in the lowest option would generally indicate light intensity and are less effective for improving cardiovascular health. The higher percentages correspond to vigorous intensity exercise, which, while beneficial, may not be suitable for everyone, particularly beginners or those with certain health conditions. Therefore, aiming for the 50-70% range is generally the safest and most effective target for moderate-intensity exercise.
