I'm new here too. I'll eventually figure out the photo thing and whatnot, since the kids are running about I don't have the time at the moment.
For motivation... think about your wedding pictures. Those babys are going to be around for a LONG time. Think about your dream wedding dress. Think about your fiance's face when he comes home from deployment and to have his jaw drop at the new you would be...amazing.
Just concentrate on losing 1 pound. Just concentrate on working out for 10 minutes at a time. I'm chasing 3 kids under 3; and I can't fathom a block of an hour for myself when I'm alone with them. I just concentrate on 5-10 minutes of doing something... anything... even dancing around like a hooligan, just to get some exercise in there.
Hang in there! You can do this!
