Bikini body mommies? (Youtube challenge)

Today I started the "bikini body mommy 90 day challenge" (youtube) - I am not a mommy yet but I liked that the girl was kinda at my level, and she lost 100lbs before so why not! Anyways after completing my day one fit test I'm kind of wishing I had some buddies to check in with to keep me accountable. Is anyone else doing this, or interested in doing it? Maybe we could start a group?
