How to Use Corsets in Body Modification. Corsetry was a practice that originally appeared back in the middle ages. It disappeared but has recently made a dramatic reappearance. There are many studies that indicate how dangerous this practice is to a person's health. However, some people use it to raise their self-esteem.
Take the measurements of your waist before you start any type of body training. If you have a particular size as a goal, then you should be able to monitor the progress.
Use a corset that is 3 to 4 inches smaller than your current size. Wear this in 2- to 3-hour stretches until you are able to wear it for 10 to 12 hours at a time.
Take off the corset at bedtime but replace it with a waist trainer that is about the same size as the corset. Wearing the trainer at bedtime will help you to wear the corset all day long.
Put on the next smaller size corset, going down in size by about 2 to 3 inches. When you're not wearing the new corset, wear the old one so you don't undo the reduction you've accomplished.
Continue to work through each of the corsets as until you reach your desired waist size.
