Lindsay Lohan is among the many celebrities of late to tout the merits of using a waist trainer. What is a waist trainer? A waist trainer is akin to the corsets of old. Women wear them and believe that doing so ‘trains’ the waist to take on a specific–very slim and trim–shape.

Lohan shared an Instagram photo of herself on Saturday. In it she wore white shorts, a pink top, and–of course–her waist trainer.

“Love my waist trainer from @nowaistclique,” she captioned the shot.

Lindsay Lohan shared a similar photo via Twitter the day before, but after followers complained that they believed the picture was Photoshopped, she deleted it and went with Saturday’s photo instead.

Even though the photo of Lindsay Lohan wearing her waist trainer shows off a tiny waistline, it’s rather hard to believe that a corset can actually ‘train’ one’s waist to look a certain way. Wouldn’t you imagine that once the garment is removed, the waistline will go back to what it was before wearing it? It seems only diet and exercise are effective at taking off pounds and inches.

Lindsay Lohan is by no means the only Hollywood star to swear by her waist trainer, however. It seems Kim Kardashian, along with sisters Kourtney and Khloe Kardashian, as well as Kim Zolciak all love their waist trainers.

Have you ever checked out a waist trainer like the one Lindsay Lohan wears? And did you find it resulted in the kind of waist reduction these celebrities claim?
