FLEX is the easiest EMS system to use. Simply fasten the belt around your waist, press the button and the exercise begins. To help you get optimum results, Flex's in-built memory and intelligent control will automatically increase your exercise levels through 4 programmes. With the FLEX unit contracting your muscles once every other second, just 30 minutes of use is the equivalent of around 900 stomach crunches, and it also helps avoid joint erosion and, combined with a short aerobic warm-up, provides an excellent energy efficient warm up/down.
