I studied Sanda for half a year before, but now I don't practice it. Is it like ordinary people?

Can't say like ordinary people. It depends on time. But speed, strength and reaction are definitely not good, and the flexibility is poor. For example, before kicking the other person's head, if you don't practice for a long time, you can only kick your shoulder. Even if you kick, it is not as lethal as before, and the coordination is poor. If you don't believe me, you can play Sanda combination boxing and combine legs. Is it as coordinated and flexible as before? Therefore, if you don't practice, you will retreat. After a long time, you will be like ordinary people.
