While exercising, you generally want your heart rate to be elevated above your resting heart rate. This indicates that your body is working harder to supply oxygen to your muscles. The target heart rate zone can vary based on your age, fitness level, and exercise goals, but typically, it is recommended to aim for a heart rate that is 50-85% of your maximum heart rate during moderate to vigorous exercise.
Maintaining a heart rate below your resting level or at your resting level would typically indicate that the exercise intensity is too low to provide cardiovascular benefits. It's best to consult with a healthcare provider or a fitness professional to determine what heart rate zones are best suited for you based on your individual circumstances.
