Hi Melanie, It's nice to see a fellow Kentuckian on these boards.
As ledom said, the EFL book was meant to be a supplement to BFL, but you can do EFL without BFL. Bill Phillips says this himself in the intro of the book.
Even if you're not doing BFL training, he highly recommends exercise of some sort. The EFL recipes taste good and are easy to make. I'm not 100% on program right now but I'm going to get started again soon.
