Basic exercises such as sit-ups, push-ups and running need to be done every day, but it is best to ask the teacher for technical actions. My child was trained in a training class at Yangjiaping Institute of Technology. The coach corrected his throwing posture and turn several times, and his score improved by nearly 10! It can be seen that physical education class, the usual teacher, can't take care of you. Maybe the teacher told you, but there is no time to urge you to practice alone. The training course is still valid. You can take the children to try it. The location is Yangjiaping Institute of Technology (next to Station 404). They are training at 3 pm on Saturday and Sunday.
