ChongErfei Sport Girdle Waist Trainer Cincher Belt

Waist trainers have been around for centuries, but a 2016 Instagram post by Kim Kardashian reignited their modern popularity. She wore it regularly after giving birth to her daughter North, and her impressive results put waist trainers on everyone’s shopping list. 

Waist trainers come in two designs: wraparound and corset. Wraparound waist trainers are built with two soft, semi-flexible arms that wrap around your waist and compress it. Corset-style trainers use rows of hook-and-loop closures (similar to bra closures) and “bones” made of steel, plastic, or acrylic to temporarily trim your tummy. Some trainers add zippers to the mix.

The trainer’s fabric is one of the most important things to consider when you’re shopping. Many people wear them under clothes or while working out, so you’ll want a breathable, soft fabric with just the right amount of give. Neoprene trainers are popular for their ability to wick away sweat, while latex trainers are ultra-breathable for hot days. 

You’ll also want to consider whether or not you want a waist trainer with shoulder straps. Waist trainers with these straps can push up the chest area to emphasize the hourglass look, while a strapless trainer is easier to wear underneath your clothes.

Now that you’ve thought about waist trainer basics, check out our Tips & Advice for more detailed ideas.

• Make sure you carefully measure yourself with measuring tape before you buy a waist trainer. The sizing is different for each style, but if you closely follow the seller’s directions you should be just fine.
• Think about where you’ll be wearing your waist trainer. If you’re going to use it at the gym, opt for trainers with sweat-wicking fabrics like neoprene. If you’re going to wear your trainer under your clothes, you might want a low-profile strapless version.
• If you have health conditions like heartburn or an irritable stomach, consider going a size up or buying a corset made from very stretchy fabric. Wearing something too tight around your midsection can aggravate these conditions.
