From a health perspective, why is measuring heart rate important during exercise?

Measuring heart rate during exercise is crucial for monitoring cardiovascular effort. When you track your heart rate, you gain valuable insights into how hard your heart is working to supply oxygen to your muscles during physical activity. It's an effective indicator of exercise intensity, allowing you to evaluate whether you are training in your desired heart rate zone—be it for improving endurance, losing weight, or enhancing overall cardiovascular fitness.

Maintaining the heart rate within a specific range can help individuals optimize their workouts for maximal benefit while minimizing the risk of overexertion or injury. This is particularly important for those engaging in high-intensity activities or for individuals with specific health conditions who may need to monitor their cardiovascular response closely.
