I think this kind of thing will take a year or two to be effective. If you want to learn it quickly, it is impossible, because you have never been exposed before, and your physical fitness will be even worse. You need more time to improve your physical fitness. It took me two years to reach the black belt. It's not easy. I think if you want to learn, you must be not afraid of hardship and be prepared for a protracted war.
Besides, learning Taekwondo is just a one-legged method. We seldom use our legs when fighting, so it is not very practical. If you play by yourself or watch others play, you should not find that you are still wrestling, so Sanda will be more practical.
But both will be hurt more or less, so don't be afraid of being controlled.
If you are really afraid of hardship, I can also suggest that you learn Aikido. As the name implies, Aikido will be softer. It uses the human body's anti-joints to restrain opponents, so there is not much restriction on physical fitness, but because it is all skills, it will take a little longer to learn. If you are interested in that, you can look up more detailed information online, because I haven't learned that for a long time, so I don't know much about it.
In addition, I think karate is also very good, I think it will be more powerful, and in some ways karate is more scientific than Sanda.
Having said that, it's time to end. In a word, I can only introduce the advantages and disadvantages of these martial arts to you, but I can't choose them for you. I think it depends on which one I like and which one suits you. No matter what others say, as long as I make up my mind, I will be able to practice. This is my QQ number +00.
