I'm practicing now, but it's Sanshou, just like Sanda, hehe.
It's definitely not too late. Any martial arts has no physical requirements.
Because all kinds of Wushu Sanda are used for fitness, the weaker you are, the more you need to practice.
Look at how many people who practice martial arts are forced to practice martial arts by their fathers because they are weak when they are young, but the result is a generation of masters.
Martial arts or fitness clubs are generally available in universities, because the universities I want to attend have them, and I have checked them all.
Moreover, my local university (which often goes to play) knows that there is a Taekwondo hall in it, which is not small enough for college students to participate in practice.
I hope it helps you, hehe.
