Are tall and fat people more suitable for those martial arts?

First of all, it depends on your purpose of practicing martial arts. If you want to stay healthy, you should practice Tai Ji Chuan. If Tai Chi is too soft, you can practice the old-fashioned Tai Chi, which combines rigidity with softness, and is very strong in fitness and aggression. If you focus on martial arts, practice long boxing. It depends on your specific constitution. If you are tall and fat, and your movements are not flexible, you should practice less jumping styles, such as Xingyiquan and Wing Chun. If you are tall and strong, you'd better practice Hongquan in Nanquan, which is Hongjia Boxing practiced by Hong Xiguan Fang Shiyu. If your legs are long and flexible, practice poking your feet and flipping your fists. If you are well-proportioned and flexible, you can practice Chaquan, Huaquan, Yuejia Boxing and Shaolin Boxing. Personally, it is not recommended to practice Bagua Palm, because the theory of boxing is profound, and it is difficult to learn and practice. It is impossible to learn without ten or eight years of hard work. Also, to practice Xingyiquan, we must learn the boxing theory well, master breathing and read more theories, because the old people in the circle say that most Xingyiquan masters don't live long because they don't practice breathing well. In short, you must learn to breathe well when practicing internal boxing, otherwise it is likely to backfire. Foreign boxing is much simpler. Also, don't be greedy, don't try to learn all the martial arts in the world, but choose a persistent practice. If you are greedy, you will not be chewed, and it will be difficult to achieve anything. In fact, no matter what kind of martial arts you learn well, you can become a master. If you can't learn well, it's no use practicing nine-yin Zhen Jing.
