New Year's Resolution

I'm new to all of this. I'm 33 years old and a mom to a 2 and 1/2 year old boy. I never really had much of a problem with my weight until after having my son. I used to be much more active. I loved to dance and workout, now the only working out I really do is chasing after my lil guy. Apparently that's not enough working out. I joined a gym yesterday and am going to be starting on New Year's Day. I'm trying to stay realistic about my expectations. I think that this site is awesome. I love how you can track calories and excerise. I think that accountability more than anything else is what's going to keep me strong and motivated. Good Luck to everyone. I hope that 2009 is a healthy one for all of us!
