Boxing mainly relies on fist attacks and body movements to dodge. The primary courses of Sanda are straight hook boxing, whipping and sweeping legs, and combination boxing. Relatively speaking, the latter technology is more comprehensive and practical.
If you have no foundation at all, it is generally recommended to go to a martial arts school to take elementary courses, and then consider exercising at home. If you don't want to go to the martial arts school, you should at least find professionals, find professional and systematic teaching videos and practice with them. Generally, you can find a lot on Youku or X Bao, which is also relatively systematic.
Finally, it is to make a reasonable training plan. This is the biggest challenge for self-learners, because you can't test the results of self-study, so it's best to find like-minded friends in social forums to learn from each other, learn from each other irregularly, and simulate confrontation, so as to know how your learning effect is.
I hope I can help you.
