Oh God, when I saw this, I pretty much died. Who knew that workout videos on YouTube could have such enlightening comments? I’m sure abs might have some part in childbirth, but it’s all about those vaginal contractions, yo. And hips, I imagine. I don’t know, maybe you ladies out there can let me know whether or not you use your abs a lot for childbirth. It’s not like I’d ever have to know about that anyway.
