The Costa Rican model has a totally enviable body.
But you'd never know it because she's MIND-BLOWINGLY fit.
Here she is at seven months pregnant.
Rockin' a killer set of abs.

The lingerie model apparently treats herself with In-N-Out Burger and mint chip ice cream.
Burgers are kind of her ~thing~.
But she reportedly manages to keep trim with pilates and healthy meals like this one of chicken, spinach, and quinoa.
And growing a tiny human hasn't stopped Sarah from posting skin-baring snaps to her 1.1 million followers.
Who can blame her?
When this is her "baby bump."
One thing's certain: That kid's going to come out pumping iron.
BuzzFeed has reached out to Sarah for comment on her insane baby body.
