In her continuing efforts to slim down , Kim Kardashian West has discovered a new gym trick, and she shared a photo of it on Thursday afternoon (August 21). The reality superstar famed for her curves revealed shes now employing the waist shaping method, which typically involves wearing a body-restricting corset for several hours a day. Kim updated her Instagram rocking a white tank, matching leggings and an impossibly tiny blue corset, with the caption #hourglass #waisttraining #nophotoshopnecessary, and a shout-out to Whats A Waist creator and CEO Premadonna . Fans were quick to flock to Kims IG post, with many eager to buy the product and watch the inches melt away we need that waist trainer! and we were just talking about waist training! were common sentiments. This method is nothing new. Corsets have been used by women to shape and contour their bodies for centuries, but what may be overlooked are the possible health risks. In a June interview with the Power 105.1 Breakfast Club , Premadonna joined the New York City radio hosts to tout the magic of her miracle product. When asked how it works, the Miami rapper and entrepreneur explained that the wearer doesnt have to diet or work out and [the garment] actually reconstructs the body.
