You're so graceful and light-hearted in every move, but I'm so...ㅜㅜ I'm going to try it with the thought that I'll improve if I keep doing it!
I think the core will be very strong just with the muscular exercise you raised!
+ Here's the question! When you exercise your lower abs and muscles in your legs. I'm trying so hard on the side split, and I'm worried I might get hurt. ㅜㅜ Is it okay to lower it slowly?
