It isn’t required to have both…but you may want both (we don’t blame you)! The benefits of having a membership and the full e-book programs are that the books are comprehensive, 12-week programs that are yours forever once you purchase them. The e-books are printable and you can flip through and see the entire program at once. Adding the Jessie’s Girls Daily membership to that means you have access to the automated macro calculator and daily workouts to follow when you’re not using the programs. They are PERFECT for when you need a few quick and awesome workouts while on vacation, between programs, or traveling but still want that detailed, Jessie’s Girls programming!
