Coaching rules?

So in one of my sources it states that when a coach is picking music and the dance style for the girls and boys on the team they need to keep in mind the audience that will be watching. It needs to have music that is easily recognized and enjoyed and is appropriate for family viewing. The song needs to have a strong beginning and a powerful ending. It also says that placement and synchronization are very important when doing the movements, it talks about cleaning up messy sections because they need to look together, for it to be a strong routine. It does not say anything about making the dance less skimpy! I would think if a first time coach was to read this book, he or she would believe any movement could be used because there are not any guidelines on which moves can be used. It is slightly disturbing thinking that if they wanted to, a coach could put a dance that resembles a strip tease into the performance, as long as they believed the audience were all overage.  This last part is just a thought it is not mentioned in the book, just letting everyone know! -the book is called Coaching Youth Cheerleading it is by the american sport education program.
