It doesn't matter without equipment. I have equipment at home now, but I don't use it much. There is a book called Prisoner's Fitness, which teaches people how to practice muscles by hand. The movement difficulty is divided into six grades, which are suitable for exercisers of different degrees. Because the link can be easily deleted, the landlord Baidu knows that it can be found by searching for prisoner fitness.

Prisoner fitness has low-difficulty movements, which can help the group practice pull-ups in the future. Moreover, before 17 or 8 years old, the difficulty of exercise is still low. Too strong movements can easily affect bone development. But you can't do difficult moves now.
