We’re always impressed by people who have the willpower to work out more than a couple times a week — but Real Housewives of Atlanta alum Kim Zolciak might take things to a new level! The blond bombshell just gave birth to twins Kaia and Kane four months ago, and she’s already rocking a body that won’t quit!

Just today, Kim took to Instagram to share a photo of herself looking thin and toned in leggings and a thermal top.

“Working in my sweats today!! I love my job! See my BFF Jen in the background!!!!” Kim captions the shot.

We’ll get to that working thing in a minute, but can we talk about how amazing Mrs. Biermann looks? This is a woman who gave birth to four children in the last three years! She might even look better now than she did pre-babies!

Now as for that “job” reference… we’re not sure what new gig Kim has picked up, but we assumed she was hard at work on a new season of Don’t Be Tardy. However, we don’t know what sort of filming they’d be doing in her closet? Maybe it’s a new spokesperson role? Your guess is as good as ours!

Share your theories on what Kim might be up to down in the comments!
