Please Join Me in Reliving the 5 Cringiest Fitness Products of the 2010's

Ugh, waist trainers. Popularized by celebrities like the Kardashians, these corset-like devices (this one costs $10-$14)are meant to be worn for hours at a time, a practice that's supposed to permanently shrink your waist if you do it for long enough. To be honest, though, there's not much evidence that they do anything except feel super uncomfortable. They might even cause breathing and digestive issues. Waist trainers are fine from time to time (for a costume or a special occasion), but they're not the secret to weight loss and an hourglass shape.
