Hello! When exercising, according to the normal cardiovascular physiological response, the heart rate and blood pressure will increase. If your heart rate rises above 100 during exercise, it's normal, you don't have to worry if you don't dare to exercise. However, if you gain too much, you should be tired, you should see a cardiologist for a full diagnosis and advice.
