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. The exercise heart rate should be kept 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.

3. Emphasize the continuous rhythm, and the effect of stop-and-go will not be good.

It usually takes 6-8 weeks to meet the above three requirements.
