Waist trainers don't actually "train" your body. In fact, Business Insider reported that the garment isn't recommended for long-term use by both doctors and personal trainers.
"If I were to take a rubber band and wrap it around my finger tightly and leave it there for an hour, I'm going to have this indentation in my soft tissue, but it's not going to be permanent," spinal surgeon Dr. Paul Jeffords told USA Today. "An hour later, my finger is going to look normal again."
According to the Daily Mail, one brand even settled a class action lawsuit for over claims related to their advertised weight loss results.
Although the corset-like trainers can only morph your body temporarily, the long-term damage they can do is what doctors are worried about. According to USA Today, the waist trainers "strangle organs" and can cause permanent damage to the spine, bones, and nerves.
