Using an Ab Roller to get a flat stomach is just one of the reason to use it. An ab roller can also be used to improve your health, not just your looks. If your exercise with an ab roller, you stand to develop stronger abdominal muscles, and these are vital to your health. In the case of major back pain, for instance, a lack of strong abdominal muscles is oftentimes a significant, contributing factor. Simple exercise, like crunches on the floor, can sometimes cause pain for those trying to do them. An Ab roller becomes one of the remaining alternatives.
