Self-publishing may be warranted if you write a manuscript on fitness.
If you have written a manuscript dealing with fitness and exercise, you may find yourself self-publishing the book in order to make it available to readers. Many publishing companies refuse to publish certain works. They believe that there are particular topics that just will not sell. Fitness and exercise may be one of the topics that publishing companies will shy away from. With the number of cardio workout instruction videos that are on the market today, many people choose to watch videos rather than reading instruction manuals or books on the subject. This is why many publishers will reject these books, and why you may find yourself self-publishing in order to get your book out to the readers who may be interested.
