New at working out....( a lil scared)...lol

I had a baby last March and so he's almost a year old. I have never been someone to work out but I gained a lot of weight while I was pregnant and have barely lost any of it. DF and I have talked about having another baby but I want to loose a little weight and be in better shape for this next baby. Anyone in the Springfield, MO area know where a good place to work out is? Also my family and I just moved here so if you know anywhere that is hiring, I could go for a job right now too. Thanks!
