That number sounds reasonable to me. There are about 1 million physicians in the US. I would think that there would be at least that many more physicians to fitness professionals. In the area where I work, I am the only fitness instructor working in the complex of offices/spaces. There are about 30 or 40 physicians working in the complex. I know that isn’t the norm, but it does point out that there are a lot more physicians than fitness professionals. And it is said that there is a shortage of physicians here in Hawaii.
