Sarah is expecting?

OK, I don't know if I can bring myself to actually post pictures of it in my own blog...but somewhere, someone is looking at picture of me and must think I am pregnant!! So I know half of the time, it can be the clothes I'm wearing, but let's be honest, I have a major food baby and it needs to go bye-bye!
I have been slacking in Weight Watchers.  I have apparently decided I think I can get by without actually tracking the food I eat.  What was I thinking? I've gained like two pounds back in two weeks.  I feel like I'm back at square one today.  And though I am a little (or a lot) disheartened by this, I am convinced to look at it as a fresh start, ready to kick some major WW butt this week!
I have been working out a lot more this week, but I've been overcompensating for "points earned." However, I have enjoyed my early morning walks a couple times this week and should make that a habit.  I have also gone for walk/jogs after work a couple times and I just love being outside, so I just need to keep it going.
But back to this nasty "baby" bump! I think I am in need of some truly amazing core work-outs that you can feel in your abs.  Anyone have any good suggestions?  I would prefer something relatively short in time, something I could get up a do for twenty-minutes in the morning.  Something that has a bit of a routine, but also makes me WANT to do it.  Am I asking for an ideal workout here?! Have any of you had any success with workouts lately? Fill me in!!
