Kim Zolciak is taking waist training to a whole new level!
The "Don't Be Tardy" star took to Instagram on Wednesday to reveal the secret behind her ridiculously tiny waist -- and it's all thanks to her new waist trainer.
"Soooo you guys finally talked me into trying a waist trainer! I can't believe how tiny it makes my waist I'm obsessed with @nowaistclique waist trainer and it doesn't show through my clothes," the former "Housewife" captioned the snap.
In the photo, the mom-of-six flaunts a whole lot of cleavage while her waist looks seriously unreal. The reality star got a tummy tuck last year and hasn't been shy about showing off her new body!
And Kim's just the latest celeb to get in on the waist training craze.
She joins stars like the Kardashians and Amber Rose, who have also snapped photos of themselves wearing the cincher.
Just last week, Khloe Kardashian showed off her tiny figure in the corset, while sisters Kim and Kourtney swear by the product.
