First of all, don't worry about getting fat, as long as you don't overeat.

Self-defense ~ ~ Taekwondo has a "sparring" part in training, which is safe in training and effective in actual combat skills (unfortunately, many places that teach martial arts not only have no "sparring" part, but teachers are even worse than gangsters! ); But the technique of Taekwondo itself is not very practical, as you said, it is "fancy". But it doesn't matter, just ask the teacher a few more questions after class! I haven't seen a black belt that can't solve students' problems.

If you want to learn more "not fancy", you have to go to Hong Kong or Bangkok to learn Muay Thai! I strongly object to girls. Ha ha. In fact, there is no need to learn any "too practical and too capable" skills. If you practice too much, you will have mental problems. Just like me, people hug me from behind and throw me out directly!

In addition, if you are interested, you can take an exam in the future. The status of Taekwondo is recognized all over the world (no kungfu can extend from the urban area to Olympic events, martial arts, Sanda, boxing, Muay Thai, etc., only Taekwondo can).

Someone upstairs said something that should be said, but I only have one reminder: if you "give up" around the age of 20, your inner thigh and hip muscles will relax, and your clothes will look a little rough. If you like it, you'd better stick to it.
