One of my favourite classes from Brian is Intermediate footwork class for Heel Toe and Toe Touchs/Swirl. The class teaches me how to pivot my foot to change directions with those basics and improve my execution in them in term of speed and accuracy. Why I like this class is because of challenge in this class. Challenge for the class may look simple in theory but it is not easy to execute and really testing my understanding on those two basics.
Really recommend strongly for more dancers to take Brian online classes. All the classes really worth the price with information packed in them. They all can be rewatch multiple times as those dance techniques and truths about system, nature and life as HUMAN is really timeless.
Buy these class to support productive HUMAN businesses!
