I agree with Joanne, if you haven’t done so, apply to present at a major fitness convention, such as IDEA. It will help you judge the response of other fitness professionals to your program and ideas.
The website that Karin cites is a great resource of info regarding how to develop and implement a certification.
Good luck, Daniel
Another route you might consider taking is presenting at one of the fitness conventions.
You can create a workshop and offer a certificate of completion. Perhaps it is something that fitness professionals can earn continuing education credits with.
I hope this gives you a bit of direction.
