Core workout for a post-partum bod

I never was a huge fan of core work. My core has always been sub-par, and I have always wanted it to be nice, but haven't wanted to put the work into it. I am not a flat belly girl, never have been. I am graced with the "no butt" figure instead of no gut. Even when I would go in spurts where I would do a lot of core, I never noticed any improvement, so I stopped. However, pregnancy has really done a number on the little core that I have. So a few weeks ago I joined a core class where I could bring my baby. Man am I glad I did. I didn't realize how weak I was until I started this class, but I can already feel myself getting stronger. Lots of planks and bridges will do this for you!
