When I was 10, 11 and 12 years old I learned how to breakdance with some of my neighbourhood friends by watching a few movies. Check this guy out:
What B.yu is showing us is called toprock, which is the dance that a breakdancer (aka a bboy) does while being vertical and up off the floor.
I wish I could dance like this guy and have created this hub as a spot for me to go to so that I can come back easily to these videos to see if I can improve how I dance. B.yu goes through explaining his moves in subsequent videos:
He goes on to provide some more steps and their instructions in the next one:
He continues the tutorial with a third part that shows some variations:
B.yu never did a fourth part, but what he provided in the first three is certainly sufficient to teach anyone how to do toprock really well.
If you are interested in learning toprock, or improving the toprock you already know with some new moves, I definitely recommend these videos.
