I do free form dancing also known as ecstatic dancing at the gym.
I have never heard of that. What does it consist of?
Well it's based on Gabrielle Roth’s "5Rhythms" guide. Are you familiar with her as an author?
I am not! Can you tell me more?
Well she is the founder of an experimental theatre company, author of three books, and she is in a band called the mirrors.
Oh that sounds interesting! I may have to check out some of her work!
You definitely should, their are a lot of teachers who currently use her 5 rhythms approach in their work. 
I am very interested in this ecstatic dancing, and I've never even heard of it before today!
Well ecstatic dance events feature a DJ and EDM music. There is no guidelines from facilitators. You are free to dance as you please.
I absolutely love EDM music!
