Our women's Copper waist belt is cleverly engineered to contour and fit your waist comfortably! This sweat waist trainer for water weight loss brings Copper infused fabric and thermal technology together. Its copper infused ions stimulate collagen production around your tummy, reduce muscle pain, stiffness and swelling. Targeted compression to your stomach muscles helps remove lactic acids and reduces vibration and strain. While its thermal technology raises body temperature in the abdominal area. Wear these slim belt shaper bands when lifting to provide compression and support to your lower back. This light-weight girdle is the ultimate fitness product that will give you a second-skin layer sensation as you workout.
