Waist trainers mold the waist, it does NOT burn fat. You choose how to wear it. Some prefer to wear it in the gym, at home, and some decide to use the waist trainer while sleeping. The more you use it, the faster results. And the tighter you keep it, the tighter waist you will get. We do not recommend to wear this waist trainer tight if you are new to the waist training. Wear it not so tight in the beginning, and then day by day you can tighten it slightly.
