Exercise time: each exercise should last at least 40 minutes, usually 50 minutes, at least 3 times a week.
Exercise intensity: Only exercise that meets the intensity requirements can consume fat. Intensity is usually controlled by exercise heart rate. It is best to keep the exercise heart rate between 1 15- 130 and lower than 1 15. If the oxygen intake is insufficient, the fat burning effect is not good. If it is higher than 130, it is easy to feel tired and difficult to persist.
