New year resolution...Getting back to shape

Hello all,
I am a working lady and in my early 30s. I used to be fit and healthy and in shape. But after my delivery I gained weight. I chose the easiest way of devulging in fast food and no exercise routine.
But now I am determined to get back to shape. People who are serious in losing weight and maintaining a healthy lifestyle please be a part of the group. Lets motivate each other and kick off the extra kilos.
