First of all, I tell you clearly that any sect in Tai Ji Chuan can achieve the goal of losing weight. If you teach yourself Tai Ji Chuan, no matter which school of Tai Ji Chuan and Tai Ji Chuan routines you teach, you will not only fail to lose weight, but will cause physical damage, because after self-study, your movements will be irregular and incorrect. Once the action is wrong and becomes a habit, it must be corrected many times, and deviation will occur. I know a person who practices Tai Ji Chuan because his movements are not standardized and correct. On the other hand, the authors of videos or books generally do not fully record the core of Taiji Chuan. Even if beginners don't understand the core things, without the timely guidance of teachers, it is easy to go astray and will definitely practice deviation. And Tai Ji Chuan's core can only be understood but not expressed. I went through this process from the beginning, and finally I had to find a master to practice, so you'd better find a master to teach, and it's most appropriate to read books and watch videos at the same time.

Generally speaking, it takes more than 10 years to learn Tai Ji Chuan (mainly introductory), so that you can defend yourself, because when Tai Ji Chuan first started practicing, the master taught by example, because the inner core things can only be understood but not expressed, depending on your understanding level. On the contrary, start late. After getting started, you can go out of the stage where the master corrects your movements and enter the stage where you can correct your movements yourself, if you encounter major problems. Combined with your own efforts, you can learn to do Taiji Chuan.
