Strengthen, tone, and firm your ab muscles with the Slendertone Flex Go abdominal toning system. Portable and easy to use, the Flex Go includes a high-quality toning belt, a set of gel pads, three AAA batteries, and a detailed instruction manual that walks you through two different toning programs for maximum results. The Flex Go is easy to use: simply strap on the toning belt and adhere the gel pads to the skin. The system will then employ medical-grade muscle stimulation technology to simultaneously work all of your abdominal muscles while you walk to the store or sit in an office chair. Signals from the belt will travel to your nerves by way of the gel pads, causing the muscles to relax and contract for an effective yet comfortable abdominal workout. The system has been clinically proven to firm and tone the abdominal area, increase abdominal strength, and improve abdominal endurance, making it a handy all-in-one training tool.
