I actually glad that Itzy toned down their choreography now. It's just dangerous and I don't see the point of Jyp brag about how hard it is. The girls suffered so much because of it. Chaeryeong was suffering from a herniated disc bc of Wannabe choreos, Yuna's neck injury, Yeji's back injury, Ryujin got knee pain and many more injuries that happened because of their tough choreography. They're still young, it will not good for their body when they get older.
What actually upset me that this can be avoided if they know the right technique and perhaps get a right dancing teacher as I know a lot of dancers with more harder choreography yet they don't hurt themselves as much as these girls.
