Check out Bringing Up Bates’ Whitney and Erin Bates’ post-baby bodies

I guess keeping up with two kids is definitely a good way to shed that baby weight.

On Season 4 of Bringing Up Bates, both Erin and Whitney Bates gave birth just weeks apart. Tonight’s Season 5 opens with the two of them rocking motherhood and clearly staying in shape while doing it.

They look so good! Whitney’s face was so thin, I almost didn’t recognize her at first.

“They sleep all night and then they have so much energy all day long,” Whitney said during the premiere about her busy schedule with the kids.

She added to the cameras, “Life with Kaci Lynn and Bradley is just so fast-paced, and especially with Zach having to work the hours he works. He works 12-hour shifts and there’s a lot of days he doesn’t get home until 11 or 12 at night.”

Whitney got such a response from people on social media wondering how she lost her baby weight, she wrote an Instagram post about it.

She said she doesn’t use “wacky diets or weight loss pills,” nor does she count calories. Instead, Whitney explains she drinks lots of water, tries to stop eating after 6 p.m., cuts down on carbs and sweets and allows herself cheat days. Whitney added that she also tries to do intense workouts like running at least three times a week.
