Explain how your target heart rate affects the levels of intensity of the exercise you perform to improve your cardio-respiratory endurance?

Your target heart rate is a specific range that indicates the optimal intensity for improving cardio-respiratory endurance during exercise. When you work out within this range, typically 50-85% of your maximum heart rate, your body efficiently utilizes oxygen, enhancing cardiovascular fitness and endurance. Exercising below this range may not provide sufficient stimulus for improvement, while exceeding it can lead to fatigue or injury. Monitoring your heart rate helps ensure you maintain the right intensity for effective training.
