If you wouldn’t mind, could you please clarify what your specific question is?
In the meantime, perhaps some of the article links I’ve provided below would be of interest to you:
I know INSANITY is part of the Beachbody package and it comes with a lot of information and supplements. I think if you are looking to start a class teaching the INSANITY program, my question to you is why would I pay money to come to your class instead of following the DVD option? This is just a curiosity question.
Maybe Beachbody can give you some tips of how to promote and sell this class.
