If the subject really wants to learn, first, find the nearest restaurant. No matter how bad the boxing gym is, the coach is worse than your own tricks (even if there is no so-called boxing class in the gym). Second, there is no library. If you really can only teach yourself, you can search online for teaching videos or buy them on a treasure. There are many complete tutorials. The problem is that if there is no sparring, you can only practice less than half. There is no way to say whether boxing can be taught by itself. If you learn boxing to fight, I tell you, you can learn by yourself, follow the video, and ponder the power chain more deeply. You don't have to do anything but exercise your muscles, do push-ups and leapfrog. Fighting is enough.
