Try a baby boot camp. At Joe Farmer Rec Ctr in Allen they have baby boot camp classes to register for...I did it last year when they had a hard trainer that was wonderful. I liked being around other moms and it helped me get over a plateau. Only did it for two weeks.
Or you can try www.babybootcamp.com; it would be cheaper at the rec center.
I spend the majority of my time working at getting my body completely back in shape since giving birth to our second child in January 2009. I breast feed for a year; plus had to do a lot to get over suffering nerve damage from an epidural amongst other things. but I fought through it and have gone from 289 to 162. I have only 17 pounds to lose. Do what you can to find motivation to workout and you will accomplish your goals. You can do it.
