I started already in this group: http://www.myfitnesspal.com/forums/show/7662-ripped-in-30-start-date-8-13-12

I'm happy to check in with anyone else starting from this group too to help motivate each other, but I have to take a break end of the month/early Sept. for a medical procedure, so I'll probably finish a week late (so around the same time as you).
