This is one of my friends, Amanda. She's super in shape and does Zumba like a billion times a week, and decided to start flexing her abs during her third trimester. Craziness ensues.
(P.S. Her doctor confirmed that this DOES NOT put the baby at risk or lessen its space...it's safe and sound in its water balloon womb!)
