Newbie looking for some motivation

Options
Hi!
I'm a stay at home mom of 3 (twin 18 month old girls and a 4 year old boy) looking for some motivating friends. I took a year off from any kind of PT after getting out of the Marine Corps, and now I'm just trying to get my energy and muscle tone back. I just started my first round of Insanity a few days ago- so if you're further along in the cycle (or just starting) I'd appreciate any helpful tips- as well as any "how to work out around 3 kids schedules" pointers! Thanks, and be sure to add me as a friend!
