We know what you guys are thinking because we're thinking it, too: How in the world does Kim Zolciak manage to stay in such great shape when she's carrying two babies in her belly and eating food like there's no tomorrow? The former Real Housewives of Atlanta star was recently asked the same question on Twitter and she has shed a little light on her secret.

Unfortunately, we have some bad news — according to Kimmie, half the reason why she looks so good is because she was born to look good. Well, that doesn't help us very much, does it?

The curious follower asked Kim, "You look FAB! What's your secret to staying fit and pregnant with twins?"

Kim responded, "Genetics honestly and I walk A LOT."

OK, so Kim does give us some hope by sharing her exercise regime, but somehow we think walking isn't going to cut it.

Even with twins, Kim is 100 percent all belly during this pregnancy, while the rest of her bod looks like it's in top shape. Maybe if Kim were in her 20s, we would understand the phenomenon that is her body a little bit better, but this woman is 35 now, people, and she's had two babies in the past two years, with two more due this month — it just doesn't make sense for her to look so incredible!

The good news is that Kim promised to take to her blog to share her tips for preventing stretch marks sometime soon. In the meantime, we'll be walking around the block. Again.

Are you amazed by Kim's bod as much as we are? Share your thoughts below!
