Has anyone done the Bikini Body Mommy Challenge? How was it?

She's starting a new 90 day challenge on Monday 9/8. I need to get back in shape so I'm thinking about following along with it -- she posts workouts on YouTube and there's also a paid meal planning guide (I'll try the free trial first). I know I just need to eat healthy and exercise, but it's always nice to have some accountability/structure.
