If it is really inconvenient for you to go to the library and school, it is understandable to go to self-study. You can start with basic training, training strength, speed, flexibility and agility. You can do sit-ups, push-ups, leapfrog and weight-bearing running by hand, and cross-train with barbells, dumbbells, speed balls, sandbags and other equipment. For technical problems, you can watch online teaching videos, compare gestures, and try to correct them repeatedly until the "standard". Finally, I suggest you find a martial arts partner nearby, put on protective gear, and fight to adjust your offensive and defensive skills.
If you don't have patience and suitable martial friends, it's ok to play sandbags for an hour every morning. After a long time, the intensity and hardness of boxing teaching will also increase a lot, which is unbearable for ordinary people. In addition, I recommend you a teaching video of Sanda king, hoping it will be of great help to you. Including boxing, footwork, wrestling, skills and tactics and other training content. , the website is as follows: /programs/view/HyLshvcpHYk/
