Hi A.,
I also gained alot of weight with my last pregnancy and was on a tight buget. I went to the library and borrowed some of their exercise videos and went for long walks. You could also try to check out the listings from you cable company, I know that they have a few exercise shows on during the day.
I aslo had borrowed a few books from the library about home exercises. They have tons of stuff there and you could probably meet up with some other moms too that are in the same situation and maybe meet someone who you can buddy up with too.
Good Luck
