Fitness trainer Massy Arias joins The Doctors to discuss the recent negative attention she's been getting online. Why? She's 5-months pregnant and rocking very impressive 6-pack abs.

Plastic surgeon Dr. Andrew Ordon wonders, "How can somebody say something negative about being in such great shape, and monitoring your weight and staying active while you're pregnant?" Massy believes a lack of education is behind the problem. She wishes everyone knew more about fit pregnancies. She also points out that she's always been this active...it's not like she got pregnant and out of nowhere decided to train for a marathon. 

"I'm actually putting my baby first. People think, 'oh she doesn't want to lose her body.' Actually no. I'm watching what I eat because whatever I eat, my baby eats," shares Massy. 

People assume that if you stay fit during your pregnancy that you're ignoring all of your doctors advice. Being active during your pregnancy can be very healthy, but please talk with your OB/GYN to make sure that you're being as safe as possible.
