Sitting reading, as long as it doesn't itch, the only actions you can do are shaking your legs, shaking your hands and shaking your head. First, shaking your legs is not a sport, and it can even be called a bad habit, because when you shake your legs, your legs will actually feel numb. Although the frequency is not low, it is not good for exercise, and even after a long time, even the heart is gone. After all, most people who love to shake their legs.
The other is shaking hands, which seems to be operable, but please fill in the picture automatically and shake hands while reading. Those who are either dancing or practicing can have something to do with a cult, so it's better not to talk about such sports. Otherwise, even if the book can be read, the people next to you will arrest you as a psychopath in minutes, because the picture is too beautiful to look directly at.
Besides, shaking my head, although in some ancient films, I used to shake my head while studying and tried this method for a certain period of time, but I found that shaking my head like this is actually very easy to get dizzy, which means that although it has an effect on moving my neck, I can't keep moving like this. Therefore, when reading a book, read it after reading it, don't think about doing any exercise, just exercise after reading it.
