Hi Adam,
I wrote two health/fitness books last year.
I wrote the books for health/fitness pros who have some sort of platform, meaning their names or systems are well known (which is important for non-fiction book publishing).
One person is the founder of a major fitness franchise - Baby Boot Camp. The other is a yoga expert and recording artist with a sibling who's a celebrity. Platform.
I wrote about getting a fitness book published on my blog not too long ago.
