Waist training involves wearing an undergarment similar to a corset, in order to cinch in and permanently reduce the size of your waist over time. The process involves wearing the corset for a short period of time at first, before increasing use. Some people even sleep in it. Kim Kardashian is using a sport waist trainer, which works by compressing your core and increasing perspiration. Join the Waist training movement and get yours today.
