Hi I'm danny and this is my WAR story. In 1996 i hurt my lower back, I wasn't really doing anything, I was just picking something up off the floor and it seized up. I started going to the doctor and the chiropractor who then recommended i come tryout these machines. i've only tried them one time so far, but i can tell already that is working something out back there and that it's doing something that i've never felt in those muscles before. I think that it is pinpointing the muscles support my lower back. It isn't really sore it just feels like i've worked out those muscles. it feels good so we'll see, I think it's going to work!
