its not a hard program to follow, to be honest. Follow the menu plan, fit in the exercise where you can. Are you a gym person, an outdoors workout person, or an at home workout type? I work out after the girls have gone to bed, thats when I have time. But it doesnt matter where you fit it in so long as you do it.
imo, if you really really want to lose the weight and get fit, then the program will work because you want it to work. I know heaps of people who have signed up and not one of them has regretted signing up.
