You’ve heard the hype about waist training and the celebrities who swear by it. But what is it exactly? Waist training refers to the practice of wearing a constricting garment — such as a corset or shapewear — to reduce the size of your waistline. As with any product, there are both benefits and risks, and many in the medical community advise against the use of waist trainers because of common misconceptions about the results and how to properly use them. However, should you choose to add the practice to your daily routine (or adopt only certain principles from it), you must be aware of the proper usage for optimal results.
