Spend 1.288 yuan to learn skipping. Children can do it without class. What other subjects are not to be taught?

One of Ms. Liu's sons in Hangzhou has a skipping task, which needs to reach more than 140 per minute, while Ms. Liu's son only has more than 40 per minute, so she spent 1288 to sign up for a skipping class in a Taekwondo gym in Hangzhou, but after signing up for the class, her son would jump before class, so Ms. Liu wanted a refund, which caused disagreement with the museum and caused dissatisfaction among netizens. No need to teach? What are the projects that can be studied?

Let's take a look at:

First, skipping rope is definitely one of them. If Ms. Liu hadn't been in Hangzhou this time, Spend 1288 yuan to sign up for class 9 truancy? I really never thought that the basic training of skipping can also be set up as a training class. I believe there are many people like me, because for us, skipping rope, like walking, will be a sport sooner or later. If you don't dance much at first, just dance for three or five days, so in my mind, this mother is too eager to achieve success.

Second, pull-ups, push-ups and so on. Let's talk about some common sports in physical education class: push-ups for men and women, pull-ups for men and sit-ups for women. These are basically courses that are not taught very much. When I was growing up, I only saw a special example. A girl couldn't sit up, but other waist exercises were good. So for the average person, these regular training courses don't need to be taught, at least they don't need to register.

Third, running. There is also running. In some gyms, there are running classes, and some people sign up for them. I can't understand this, because as far as sports are concerned, it's nothing to come to the gym to play the treadmill if you just choose to run, but it's incomprehensible to sign up for a class to learn to run, just as a large number of netizens can't understand why skipping rope also signs up for a class.

In a word, practice makes perfect in some sports, and few people sign up for these sports. However, as far as Ms. Liu is concerned, she missed the later courses. I support her refund, but I think she should pay 20% of the liquidated damages according to the contract.
