All about Heart Rate and Exercise
Your heart rate is the number of times your heart beats each minute. It goes up when you exercise because your muscles need more oxygen and energy. When you rest, your heart rate slows down again.
Measuring your pulse on your wrist or neck can show how hard your heart is working. Regular exercise helps the heart become stronger over time.
