Heart rate after exercise is different depending on the exercise. The more intense the exercise, the higher the heart rate. It is usually best to keep the exercise heart rate at 120 to 150 beats per minute. For low to moderate intensity exercise, the heart rate is around 110 to 140 beats a minute, and for more intense intensity, such as like weight loss exercise, the heart rate will be around 150 beats a minute with a maximum of no more than 210 beats a minute. There is a certain amount of variation in heart rate, i.e. heart rate variability, which can be individualized by age, gender or other physiological factors. The younger the person, the faster the heart rate, the older the person, the slower the heart rate, and the faster the heart rate of women compared to men. If there is chest tightness or palpitations that are not relieved after resting, it is recommended to consult a doctor as soon as possible to avoid delaying the condition.
