First, if the heart rate during exercise is taken as the standard, it can be calculated by the following formula: the heart rate of people under 60 years old during exercise = 180- age (10); People over 60 years old: heart rate during exercise = 170- age (10). If you feel unwell or tired after exercise, or your heart rate has not returned to a quiet state after 15 minutes of exercise, it means that you have done too much exercise and should adjust it in time.

Second, body mass index (BMI): BMI can usually reflect whether your current weight is suitable for your height, so as to decide whether you need to increase exercise. For the average person, under normal circumstances, it is an ideal range for the body mass index to remain between 18.5~24.9. Calculation method of body mass index (BMI) = weight (kg)/height (m)/height (m).

3. Muscle endurance, muscle strength and flexibility: Muscle endurance refers to the endurance that muscles can effectively contract and relax, muscle strength refers to the maximum external force that muscles can overcome in a contraction process, and flexibility refers to the range of motion that a joint or a series of joints can produce. These three indicators should be able to reach the standard through moderate exercise.

Fourth, blood pressure: A healthy blood pressure index should be the result of proper exercise. Not too high and not too low.
