Okay I don't know if someone knows about Jumpstyle.
Jumpstyle is a dance and a type of music, created in Belgium.
It's a part of the Hardstyle category. The dance is a combination of different movements, and each time you jump a little to make it. You use your arms juste to regain jour balance.

It's a dance which seems easy, but when you try it, it's much harder than you think it is!!!
You only dance with the beat.Some people are trying to dance with the music and not the beat, so it's not beautiful

Here's a video of two people dancing Jumpstyle
the music is a remix Of "Les Lacs du Connemara" by Michel Sardou.
Here it is:
