Sia Cooper is the fitness guru inspiring moms across the nation with her site Diary of A Fit Mommy. Over the past few few months we've watched Sia's workout routines go viral and followed her journey to Baby No. 2. She recently opened up to VH1 to update all of her fans and supporters on her post-baby progress. Amazingly, her body snapped back in just two weeks! She also gave us the following shoutout:

'My absolute favorite prenatal workout gear is from Belabumbum’s Active Collection. They are also nursing-friendly and can be worn postpartum, which is a big bonus for us moms.'
