Motivation

Once upon a time, I ran 1/2 marathons, I climbed mountains, I did sit-ups and work out videos. 2 babies later, I have excess flab, little time and very little motivation. However, spring is in the air and my BOB is a great walking buddy. I'm lacking a little motivation and am begging for encouragement. How did you get back into the fitness thing post-baby? Know a great Zumba class or Boot Camp in my neck of the woods you can lure me to? I'm off to strap on my beat up runners and slog/walk the lake. It's a start, right?
