Let’s start with, why a waist trainer? A waist trainer is a high-compression shaping garment that you wear around your midsection to slim your waistline instantly and supplement your fitness goals. Most waist trainers stimulate thermal activity in your core, from the neoprene material, making you sweat more with less effort during exercise.

Our “Core Tight” waist trainer benefits include a more effective workout, improved posture, and dramatic hourglass curves—instantly. One of the unexpected benefits of wearing a waist trainer is better posture. It’s something that many of our customers have been pleasantly surprised to discover, and it’s one of their favorite benefits. Professional women who sit at a desk all day tend to slouch, which is a big no-no for your back. While wearing a waist trainer, the compression forces you to sit up straighter and thus provides more posture support.

The corrected posture is good news for your back, but that's not the only benefit. You’ll look and feel more confident simply by the way you carry your torso. It's a look of confidence. Nonverbally you can send a powerful message just by standing a little taller.

This set is by far one of my faves! I love the material and the way it makes my cellulite disappear! Also, the fact that I get to switch from pants to shorts is so bomb!!

I recommend this product.
