A heart rate over 200 beats per minute (BPM) during exercise is generally considered too high for most people.
Generally, a target heart rate for moderate-intensity aerobic exercise is between 50 to 70 percent of your maximum heart rate, and for vigorous-intensity aerobic exercise, it's between 70 to 85 percent of your maximum heart rate.
It is recommended to aim for a heart rate within your target heart rate zone, which can be determined by your healthcare provider.
If you experience symptoms such as chest pain, shortness of breath, lightheadedness or dizziness while exercising, it's important to stop and seek medical attention.
Monitoring your heart rate can provide valuable information about your body's response to exercise and can help you to ensure that you are working out at the appropriate intensity level.
For example, monitoring your heart rate during endurance training can help you to ensure that you are working at the correct intensity to improve your fitness.
Additionally, people with certain medical conditions, such as heart disease, may benefit from monitoring their heart rate to ensure that they are not overexerting themselves during exercise.
