The ProsourceFit Waist Trimmer Belt is a perfect addition to your fitness routine, offering both core support and muscle-warming coverage. A soft, textured neoprene interior helps the belt stay in place when you’re working out or in the sauna and is comfortable for all day wear and back support. A Velcro closure allows you to get a custom fit, creating a sauna-like atmosphere around your mid-section to maximize perspiration. The increased blood flow keeps muscles warm and helps you to shed excess water weight - perfect for wearing while you exercise. This basic body-shaping wrap comes in three sizes – M: 9"x46", L: 10"x51", XL: 10”x60” - for full coverage on a variety of users and an excellent option for post pregnancy recovery.
