Hello ~ From my personal point of view, I still support swimming ~ Because I used to be a table tennis player myself ~ I started practicing from the age of five until I was over twelve ~ I don't know how far you want to practice table tennis ~ But I think ~ First of all, it is very complicated and difficult to play, although I have won some prizes ~ Many teammates who continue to play table tennis are now retired; Secondly, hehe, practicing table tennis is not very plastic, especially the legs, but very muscular. But it's much better to swim ~ it's not only quite plastic, but also there are venues everywhere when you want to swim, which is more convenient. Besides, I think swimming is easier to master in a short time, except that butterfly is less technical than table tennis. As for improvement, that's your own business, but table tennis doesn't have to be watched by a coach. But judging from your tone, it seems that you like table tennis ~ it doesn't matter ~ the choice is yours. Suggestions are for reference only.
