Reach your body goals in no time The Ultimate Waist Trainer is engineered with our signature technology that traps heat and increases your sweat output. This full-coverage belly band shapewear is designed with a Velcro strap to provide medium-level compression and additional support. It helps you sweat more around your lower back and abdominal areas, reducing water weight. The compression strap and flexible rods work together for increased comfort as your waist shrinks. The design makes it perfect for all body types while offering full coverage, back support, & sweat-inducing tech for accelerated fat loss.
