Together with the beginning of warm-up activities and the end of finishing exercises, it is appropriate to practice for about 50 minutes. If time or physical health does not allow, you can arrange exercise 1 ~ 2 times a day, each time 15 ~ 30 minutes, and the times are 1 ~ 2 times. You can also take the whole set apart and choose the movements suitable for your own practice, which can also achieve good exercise results.
